lcd display burn in brands

Have you ever left your TV or monitor on for days, stuck on the same image? You return to your screen, only to find an image burned into the display. No matter what you do, it won"t go away. It is a permanent image burn.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

In some cases, you can minimize the image burn effect. In others, you can remove the image burn completely, so long as it hasn"t been burning too long.

Before flat-screens and crystal displays, most TVs and monitors featured CRT (Cathode Ray Tube) technology. In CRTs, individual pixels comprise a red, blue, and green phosphor component. Depending on the intensity of each phosphor component, the pixel appears to the human eye as a unique color.

When a particular still image remains for too long, the intensity of each phosphor component diminishes at an uneven rate. The result is a ghost image on the screen, which is known as image burning.

Plasma displays use plasma, a gaseous substance containing free-flowing ions. When the plasma is not in use, the particles in the plasma are uncharged and display nothing. With the introduction of an electric current, the ions become charged and begin colliding, releasing photons of light.

This is a very simplified version of how a plasma screen works. However, the main thing to understand is that plasma screens use phosphor material (like CRTs) to turn those photons into images.

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

First, let"s tackle plasma screen burn-in. Remember why CRTs experience image burn? When a still image remains on the screen for too long, the phosphor components in each pixel wear out at different rates. The uneven burn rates leave behind a ghost image, forever etched into the screen.

Plasma screens also suffer from phosphor deterioration. Plasma burning occurs when pixels on the screen are damaged through long exposure. The phosphor loses its intensity and only shows the light it was fed repeatedly. In this case, the still image, which causes the burn.

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

Image retention is a different issue from image burn (although it is a precursor to image burn). For example, you"re using an image of a steam train as a reference point for a drawing. You have the steam train image on your screen for a few hours before you decide to play a video game instead.

When you load up the video game on the screen, you can still see the faint outline of the steam train on the screen. The steam train image will remain for a short while, but the movement and color changes of the video game (or film, TV show, or other media type) should erase the retained image.

The other thing to consider is that LED and OLED image burn-in, when it happens, is irreversible. That"s because of how LED and OLED screens work. Individual pixels within an LED display decay when they emit light.

Under normal use, an LED, OLED, or QLED screen won"t suffer image burn. However, if you leave your screen on a single channel for hours every day, then burn-in can become an issue, as it would with almost any screen.

Issues arise when a screen shows a single news channel 24 hours a day, every day, causing channel logos to burn-in, along with the outline of the scrolling news ticker and so on. News channels are a well-known source of television burn-in, no matter the screen type.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

The best fix for screen burn is to prevent it in the first place. Okay, that isn"t super useful if your screen is already experiencing image burn. However, you should always try not to leave your screen on a still image for too long. The time it takes for an image to burn-in varies from screen to screen, between manufacturers, sizes, and panel type.

My personal rule of thumb is to turn off the display if I plan on being away for more than 15 minutes. That way, it is difficult to get caught out, plus you save yourself money on electricity costs and monitor or TV wear and tear.

Another prevention method is to reduce screen contrast as much as you can. Unfortunately, most screens aren"t calibrated correctly, often pushing the contrast and brightness settings too high.

Lower contrast means the lighting across your screen is more even. This means less strain on specific areas of the screen, which helps protect against image burning.

If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.

Unfortunately, this won"t work for extreme cases. Some TVs will have a built-in pattern swiping option that basically accomplishes the same thing (filling your screen with random patterns).

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

Other modern screens feature built-in screen refresh functions that the manufacturer will advise using to remove image retention and image burn issues.

The best tool for fixing ghost images is JScreenFix. The original program helps fix monitors with dead pixels, but the same company also released an "advanced" version of the tool, known as JScreenFix Deluxe.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

You can find the free version of the Deluxe app online, but it is limited to 20 minutes running at a time. Furthermore, we"re not going to link out to the versions you can find online as we cannot verify the security of these installations. If you do use the Deluxe version, you do so at your own risk.

Another option is to set a completely white desktop background and leaving to run for a few hours. The solid color might reset the image burn. A solid color background is more likely to help with image persistence than image burn, but it is still worth trying.

If you have television burn-in, you can attach a laptop to your TV using an HDMI cable, extend your desktop to the television, and share the white screensaver. Hopefully, that will shift your television burn-in.

The team over at ScreenBurnFixer offers a few different ways you can attempt to fix screen burn on your TV or monitor. As with any other screen burn-in fixes, their chance of working depends on the scale of the issue.

You can head to the ScreenBurnFixer Video page and find a video that matches your screen type, then let the video play for as long as possible (we"re talking multiple hours, not a quick half an hour blast). Alternatively, head to the Chart page and find your device or a device that matches your specifications.

There are several ways you can attempt to fix screen burn-in. The results will vary between the screen type and the level of burn-in. A screen with extensive image burn may not clear entirely, although you might see an improvement.

Some screen degradation over time is understandable. However, if you follow the steps in this guide, you"ll protect your screen from image burn before it becomes a permanent issue.

If you spend long enough debating the merits of LCD vs. OLED display technologies, eventually, someone will touch upon the subject of the dreaded OLED screen burn in. The point made is that OLED displays will inevitably suffer from horrible-looking artifacts over time, while LCD and new technologies like Mini-LED won’t. But like most of these debates, you’ll probably hear as many overblown anecdotes as you will actual facts about the issue.

You may never have experienced it for yourself, but many consumers are wary about the possibility of burn in when pondering their next smartphone purchase. Particularly as expensive flagship smartphones have universally adopted OLED display technology. Apple, Google, and other manufacturers acknowledge that burn in can be a problem in rare cases. OLED technology has made its way to much more affordable price points in recent years, putting the issue on the radar for even more consumers.

The word “burn in” is a little misleading, as no actual burning or heat problems are involved. Instead, this term describes a display suffering from permanent discoloration across any part of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches and patterns on display. The display still works as expected, but a somewhat noticeable ghost image or discoloration persists when the screen is on. To be considered screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side. Rather than a graphical glitch that may be caused by software, temporary image retention, or a problem with the display driver circuitry.

The term dates back to old CRT monitors, where phosphor compounds that emit light to produce images lost their luminance with time. LCD panels can exhibit similar problems, but these are much rarer due to the nature of LCD’s backlight and color matrix design.

Although not as bad or noticeable as old CRT issues, today’s OLED smartphone displays can eventually suffer from a similar problem. That being said, it’s pretty difficult and rare to notice unless you know what you’re looking for, and it takes hundreds, if not thousands, of hours of screen-on time before any such errors appear. In smartphones, pattern burn in is typically associated with always-on displays, navigation buttons, and the notification bar. The example below demonstrates a textbook case:

Although most smartphones now support gesture navigation controls in the place of the old button design. So this type of burn-in is much less of a problem than it used to be.

The cause of all screen burn in is the varying lifecycle of a display’s light-producing components. As these parts age, their brightness changes, and therefore the panel’s color reproduction gradually shifts with time. Although this can be mitigated somewhat with clever software, all displays experience some color shift as they age. But with burn in, some parts of the screen age faster than others. This can gradually shift the perceivable colors of the screen in one area more than in another, leaving what looks like a ghost image behind.

With modern smartphone and smartwatch technology, screen burn in can manifest due to the different life spans between the red, green, and blue LED subpixels used in OLED panels. As we mentioned before, areas of the display that seldom change, are bright white, or are often black and switched off, such as navigation buttons or the notification bar, are the most likely areas to notice this issue. You may also notice the effect in darkened status bars designed to hide display notches.

This is because these areas are more likely to consistently display one color, a set icon, or text. In contrast, the rest of the display produces a more random selection of colors from various websites, videos, apps, etc., over a long period of use. Therefore the subpixels in these areas see different amounts of use and thus age differently, eventually resulting in a slight variation in color reproduction. Switching to transparent and color-changing bars has the added bonus of evening out the color aging process.

Speaking more technically, the issue is that blue LEDs have significantly lower luminous efficiency than red or green pixels. This means that a blue LED needs to be driven at a higher current for a set sized pixel to achieve the same brightness as red or green. Higher current causes the pixel to degrade faster, shortening its lifespan and eventually tinting the display towards the red and green colors. Therefore an OLED display’s color doesn’t degrade evenly; it will ultimately lean towards a red/green tint.

So, if one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas. That’s essentially what burn in is. However, display manufacturers do account for this in their panel designs.

If OLED screens have a problem with burn in, why do we continue using them? Burn in is a true downside to OLED displays, but there are plenty of reasons consumers and manufacturers like them. For starters, image quality is much better than in LCDs. OLED panels can reproduce more vibrant colors, more contrast, wider viewing angles, and faster refresh rates. Colors tend to be much more saturated, and blacks are much darker.

OLED displays have a simpler design, allowing thinner, lighter smartphone designs. You can also thank OLED technology for foldable phones and curved displays. If those improvements weren’t enough, you’ll also enjoy lower power consumption with OLED.

Additionally, burn in problems are only common after prolonged periods of use. As you may already know, smartphone manufacturers don’t expect you to keep a smartphone for more than 2-3 years. Recent statistics show that consumers currently keep their phones for an average of 2.75 years.

At this stage, manufacturers are very aware of the potential issues and have already taken some intelligent steps to help avoid burn in. For starters, Samsung has been using its pentile subpixel arrangement in its AMOLED displays since the Galaxy S3. By making the blue subpixel larger, it requires less current to drive in order to provide the necessary light. Driving the LED with less current increases its lifespan, so it takes longer for any noticeable color shift to occur.

This doesn’t directly address the issue of different parts of the screen aging at different rates, but it does mean that it will take significantly longer to notice than with older or cheaper OLED panels. More expensive and modern OLED panels are built with longer-lasting LEDs and well-designed layouts, meaning flagship smartphone displays age slower. These days, it’s cheaper phones packing cheaper displays that are marginally more likely to see issues after heavy use.

There are software solutions too. Android Wear product manufacturers can enable the OS’s “burn protection” option. This mode periodically shifts the screen’s contents by a few pixels, so they spend equal time displaying different colors. Smartphones equipped with Always-On display technology employ a similar tactic. Google also suggests a selection of design guidelines tailored to avoid screen burn-in problems when designing OLED watches. The move towards gesture rather than on-screen navigation controls is also helping to alleviate one of the more noticeable burn in areas.

If your screen is already burnt in, there’s not much that can be done to undo the damage. Some apps on the Play Store claim to reverse the problem. These will end up “burning” the rest of the screen to match the colors, which isn’t a real solution.

Keep your display brightness as low as reasonable. Increased brightness requires more current and therefore shortens LED lifespans. Don’t crank up the brightness unless you have to.

Try to make it so that the screen isn’t displaying the same thing all the time, in the same areas of the screen. For example, if you have a widget that almost always looks the same, chances are it will eventually burn into the image. Move things around now and then, and try to keep the view of your phone dynamic.

All that said, screen burn in isn’t something that should concern many users if they’re looking to buy a new OLED smartphone. Modern panels have much longer lifespans than early OLED smartphones, and even then, burn in was rare. Just don’t leave a static image on the screen 24/7 with the brightness set at max.

The bottom line is that you should be looking at several years’ worth of use out of a modern smartphone display before any screen burn in will be noticeable. But it doesn’t hurt to be aware of what can happen to aging handsets and how to maximize their lifespan.

Expressly designed and tested for security and surveillance environments, AG Neovo’s patented Anti-Burn-in™ technology tackles the LCD monitor burn-in effect, otherwise known as a ghost image on the screen. Burn-in images result in the polarisation of the liquid crystal material contained within the TFT LCD panel. The Anti-Burn-in technology prolongs the lifetime of all AG Neovo monitors and displays featuring this technology to secure users’ investment.

LCD Burn-In, known as image sticking, image retention, image persistence, or ghost images, is the phenomenon where fixed images displayed on the monitor screen for extended periods cause the polarisation of the liquid crystal material contained within the LCD panel, making the image to be “burnt” on screen.

Burn-in on an LCD screen occurs because pixels permanently cannot return to their relaxed state after a static image is displayed on the screen over a long period of time. When a screen keeps displaying a single image, the crystals at those pixels will get a permanent memory, and thus the image on the screen will be imprinted onto them permanently. Once it causes screen burn-in, there is no recovery in most cases. Because of this, choosing a display or monitor allowing for pixel shift, like AG Neovo’s monitors with Anti-Burn-in, can help prevent LCD computer monitor burn-in.

“Image retention” and “Burn-in” are sometimes used interchangeably, but they are not precisely the same thing. Image retention, in most cases, is temporary and fixable. It appears when an image is temporarily “stuck” on the screen even if the content changes, but reversible by taking particular measures. Burn-in on the LCD screen is a form of image retention but is permanent and virtually impossible to fix. The prolonged use of static images would cause screen burn-in.

AG Neovo’s patented Anti-Burn-in™ technology tackles the LCD monitor burn-in effect, otherwise known as a ghost image on the screen. Burn-in images result in the polarization of the liquid crystal material contained within the TFT LCD panel. This technology prolongs the life of all AG Neovo monitors and displays to secure the user’s investment.

Anti-Burn-in technology is to activate the pixels to move by the designed time interval and protect panels from being seen the vaguely visible “residual image” under the static charge conditions so as to help prolong the lifetime of TFT LCD panels.

The patent on the Anti-Burn-in technology shows that AG Neovo places importance on its display quality to prevent image burn-in. To best fit the requirement of the security environment, Anti-Burn-in Technology is invented with high-level flexibility and effectiveness. There are three types of mode:

Execute faster than the Line and Dot Intervals. Frame Movement is to move the entire video frame horizontally and vertically (right/left/up/down) for a preset time interval.

Slower but more precise than the Frame Movement. Line Movement is to scan the screen starting from top to bottom and left to right with horizontal and vertical moving lines for a preset time interval.

The slowest but the most precise Anti-Burn-in mode. Dot Movement is to scan the screen with a set of “black & white” dots or pixels in left-to-right and top-to-bottom directions.

Unlike conventional displays, AG Neovo’s security and surveillance displays are built-in with Anti-Burn-in function to reduce the possibility of LCD burn-in for continuous security monitoring applications. It is not needed to create any screen saver, playback youtube video, or install additional tools to prevent burn-in effect.

Compared to the traditional LCD screen burn-in reduction tools which may cause evident interruption to the displayed images, AG Neovo’s patented Anti-Burn-in function is almost unnoticeable when applied. The specially designed three modes of Anti-Burn-in selection provide users with flexibility in choosing the optimal approach that best fits with their non-stop security monitoring.

Video surveillance is commonly used for monitoring of selected images to determine if an improper activity is occurring, such as theft, vandalism, and abnormal situations in daily operation, and any intervention is not allowed during the process. To ensure there are not any interruptions to the video monitoring, turning on a screen saver, reducing contrast/brightness or playing white static image for a particular while is not an option. Instead, selecting a security monitor with built-in Anti-Burn-in function is an efficient solution.

Burn-in on the screen is technically hard to fix. Instead, here are some tips on how to remove image persistence on LCD screens and prevent permanent effects:

Enable the “Pixel Shifting” function on your monitor or display. Most of AG Neovo monitors have a built-in Anti-Burn-in, which allows varying pixel usage by activating the pixel to move at regular intervals. If not enabled automatically, you can manually turn it on and try to alleviate any image retention problems.

Reduce screen contrast and brightness. Lower contrast allows even lighting levels across the LCD screen and thus has less strain on a specific area of the screen. Then, try to watch some different contents, and the effect of Image retention might go away on its own.

Turn on white static image for approximately as long as the persistent image was displayed; this is to use a completely white screen to overwrite the burn-in image. Or, create a screen saver that alternates between black and white images. The continuous changing of white/black across your screen can help alleviate the ghost image from the screen. The solid colour background might reset the image burn but is more likely to deal with image retention than image burn-in.

Ever notice a partial discoloration of text or image across the screen of your monitor? This can be annoying, especially when the monitor is an industrial display used to help your business.

These unpleasant discolorations are known as screen burn-in. In this blog post, we will discuss how to prevent and recover from LCD monitor screen burn-in.

LCD display burn-in, also known as ghost image or image sticking, is the retention of the previous image on the screen even after you’ve swiped the screen. LCD burn-in happens on an LCD screen when pixels cannot return to their relaxed condition after a static image shows on the screen for an extended period.

Technically, these are two different things. Image retention occurs when your display swiftly shifts from one image to another. For example, image retention occurs when you briefly notice the “shadow” of the first image in the second.

LCD monitor screen burn-in is the permanent version of image retention. Screen burn-in occurs when an image is shown on a screen for so long that it may still be seen after the screen is off. LCD burn-in happens when some sub-pixels have remained so brilliant for a very long time that they are unable to go back to their initial state. They always produce a “ghost” image because they are inherently “stuck” in a non-neutral state.

When pixels stay in the same place for an excessively long time before switching to another position for a brief period, this can lead to LCD monitor burn-in. In addition, when an image is displayed on a screen excessively, the liquid crystal material in the LCD panel becomes polarized. As a result, it develops into a permanent discoloration known as LCD display burn-in.

Image persistence on LCD screens is avoidable and can be corrected. There are several ways to prevent or repair screen burn-in in LCD monitors, which include the following:

Screen burn-in isn’t as common on modern display technologies as it was in the past, but few screens are immune to its ability to ruin a perfectly good display. If you run into this irritating problem, here are some tips and tricks that might help fix it.

Screen burn-in is a noticeable discoloration or ghosting of a previous image on a digital display. It’s caused by the regular use of certain pixels more than others, leaving them to display colors slightly differently. The end result is a noticeable and often permanent impression on the display.

Time, screen brightness, and other factors can cause burn-in, but the circumstances are different for each display technology, as different screens and their pixels operate differently at the hardware level. For LCD panels, like those used in many TVs and computer monitors, burn-in can develop because pixels eventually become unable to return to their unlit state and retain a colored profile.

As for OLED and AMOLED technology, which is now used in some modern smartphones and TVs, the light-emitting pixels in the displays can dim faster than others if used more regularly, leaving a darkened ghost of an image in their place.

Colloquially “burn-in” is used as a catchall term for any kind of ghosted image on a screen. The most common form of such “burn-in” though, is technically known as image retention. While that might seem like a case of pedantic semantics, it’s an important distinction to make. Screen burn-in refers to permanent degradation of a display which is almost impossible to fix; image retention is typically fixable.

As described above, screen burn-in on a technical level is hard to fix. However, the much more common image retention is not. Here’s how to sort out your image retention problems on whatever device you have.

Enable Pixel-Shift. Many modern TVs have a built-in pixel-shift, or screen shift, which constantly moves the image slightly to vary pixel usage. If not enabled automatically, you should be able to turn it on in the settings menu. Other settings offer “Refresh” functions that can be manually run to try and clean out any image retention problems.

Play a colorful video. Running a fast-moving video with lots of color changes for a few minutes to half an hour may help if the above options don"t work.

Use a White Screensaver. Try setting your screensaver to a pure white image and leaving it to run for a few hours. That may not remove image retention entirely, but it should dampen how noticeable it is.

Try JScreenFix. Some have also found success using JScreenFix. Although designed to fix stuck pixels rather than burn-in, it may help clear up any issues you’re experiencing.

Try a burn-in fixer. There are a number of great burn-in fixer apps on the Google Play Store and Apple App Store. Some, like OLED tools, will try to fix image retention and check for more permanent burn-in.

Replace the screen. If none of the above works, your best bet is to either replace the screen yourself or talk to your mobile carrier about a replacement device. Manufacturers like Apple have extended the warranties on certain devices that are prone to image retention and burn-in, so if your device is fairly new, you should still be covered by the warranty.

To prevent screen burn-in on a TV, reduce the brightness to the 45-50 range, use the sleep timer and screen savers, and turn the TV off when not in use. If you have an OLED TV, turn on pixel shift and play a color-changing video that"s designed to help lower the risk of burn-in.

On Androids and iPhones, reduce the brightness to 50 percent or lower, use a screen-timeout length of about 30 seconds, and turn off your phone when not in use. You can also operate in dark mode, use swipes and taps instead of button navigation, and download a screen-burn fixer app.

On a smartphone, screen burn presents as a discolored display with pink or gray tones. On monitors and TVs, it looks like a "ghosting" of previous images remaining on the screen. Screen burn happens so gradually that you may not notice it until using a white background.

One of the problems with old CRT monitors, over time, was a condition called burn-in. This phenomenon resulted in an imprint of an image onto the display that was permanent, caused by the continuous display of a particular picture on the screen for extended periods. A breakdown in phosphors on the CRT results in the image being burned into the screen, hence the term. Is there such a thing as LCD screen burn-in?

LCD monitors use a different method for producing the image on the screen and are immune to this burn-in effect. Rather than phosphors generating light and color, an LCD uses a white light behind the screen with polarizers and crystals to filter the light to specific colors. While LCDs are not susceptible to burn-in the same way CRT monitors are, LCDs suffer from what manufacturers call image persistence.

Like the burn-in on CRTs, image persistence on LCD monitors is caused by the continuous display of static graphics on the screen for extended periods. Long-term-static images prompt the LCD crystals to develop a memory for their location to generate the colors of that graphic. When a different color appears in that location, the color will be off and will display a faint image of what was previously displayed.

The persistence is the result of how the crystals in the display work. The crystals move from a position allowing all light through to one that doesn"t allow any. It"s almost like a shutter on a window. When the screen displays an image for an extremely long time, the crystals can switch to a particular position. It may shift a bit to alter the color, but not completely, resulting in a display other than the one intended.

This problem is most common for elements of the display that do not change. Items that are likely to generate a persistent image are the taskbar, desktop icons, and background images. These tend to be static in their location and displayed on the screen for an extended period. Once other graphics load over these locations, it might be possible to see a faint outline or image of the previous graphic.

In most cases, no. The crystals have a natural state and could shift depending on the amount of current used to generate the desired color. As long as these colors change periodically, the crystals at that pixel should fluctuate enough, so the image doesn"t imprint into the crystals permanently. However, if the screen is always on the image that doesn"t change, the crystals could obtain a permanent memory.

Set the screen to turn off after a few minutes of idle time. Turning off the monitor display prevents images from appearing for extended periods. Setting the monitor to do this when the computer is idle for 15 to 30 minutes can make a difference. These values appear in the Mac Energy Saver settings or Windows Power Management.

Rotate any background images on the desktop. Background images are a common cause of image persistence. By switching backgrounds every day or every few days, you"ll reduce the risk of persistence.

Using these items can prevent the image persistence problem from cropping up on a monitor. If the monitor displays image persistence problems, here are a few steps that can be used to correct it:

Use a screen saver with a rotating image and run it for an extended period. The rotating color palette should remove the persistent image. Still, it could take a while to remove it.

On August 31, 2017, we started a long-term 20/7 burn-in test on 3 TVs (OLED vs VA vs IPS). Our goal was to see how their performance changed over time, especially with static images like network logos, black bars in movies, or video games with a fixed interface.

We already test for temporary image retention, which generally subsides over a few minutes. It"s a temporary annoyance and results in some faint artifacts usually visible in high contrast areas.

Permanent image retention is a more serious issue, but it requires looking at the TV"s performance over months or years. We tested three TVs side-by-side, the OLED LG B6, the VA Samsung KU6300, and the IPS LG UJ6300 in a two-year-long test.

This test ended in 2019, as we feel that we now have a good understanding of what types of content are likely to cause burn-in. However, we still haven"t addressed the issue of longevity in general, and we don"t know if newer OLED panels are still as likely to experience burn-in. To that end, we"ve decided to start a new accelerated longevity test to better understand how long new TVs should last and what are the most common points of failure. Although burn-in isn"t the main goal of this test, we"re hoping to better understand how newer OLED panels compare to the older generation of OLEDs. It"s generally accepted that burn-in isn"t as much of an issue as it used to be, but it"s unclear just how much better the newer OLED TVs are. With new panels, new heatsinks, and even brand-new panel types like QD-OLED, there are a lot of unknowns.

The 20/7 burn-in test ran for about two years, from August 31, 2017, until November 15, 2019. The goal of this test was to see whether burn-in could happen for the three most popular TV types (VA LCD, IPS LCD, and OLED). These are the results of our experiment:

Long periods of static content will cause burn-in on OLED TVs. The red sub-pixel appears to degrade the fastest, followed by green and blue. The effect is cumulative, as even cycled logos do burn-in (but over a longer period). We investigated this further in our Real Life OLED Burn-in Test.

The "Pixel Shift" option on the OLED LG B6 can help spread static content over more pixels (so each pixel displays the same content for less time), but it"s not as effective for our large logo. It may be helpful for very small static areas.

Black letterbox bars were displayed for almost 5,000 hours (equivalent to 208 days of continuous letterboxing). Some letterboxing is starting to become noticeable on full-screen slides, but not in normal content. As a result, we don"t expect letterbox bars to cause any issues for people. It"s due to the uneven aging of the screen. The black portions of the screen haven"t aged as much as the rest, so those dark areas appear brighter in regular content.

Some of the LED backlights of the UJ6300 died, so the image is unwatchable. To keep a constant brightness of 175 nits across these TVs, the UJ6300"s backlight was turned up to maximum, while the other TVs achieved this brightness at a lower backlight/OLED Light setting. It may mean that it has been operating at a higher temperature, contributing to the failure.

The TVs were placed side-by-side in one of our testing rooms, as shown to the right. The TVs stayed on for 20 hours a day, seven days per week, running our test pattern in a loop. They were turned off for 4 hours each day using USB infrared transmitters connected to each TV and controlled by a PC to better represent normal (but still very heavy) usage. On the B6, the "Pixel Shift" option is enabled. A single Android TV Box was used as a source, with an HDMI splitter used to provide the same material to each display.

We used our calibration settings, as shown on the review page below, but with the backlight adjusted to reach 175 nits on our checkerboard pattern and no white balance settings applied.

A 5.5-hour video loop was used as the test pattern. It was designed to mix static content with moving images to represent typical content. The base material is a recording of over-the-air antenna TV with an overlay of RTINGS logos of different opacities and durations and added letterbox black bars. These additional elements are:

Screen burn-in, image burn-in, or ghost image, is a permanent discoloration of areas on an electronic display such as a cathode ray tube (CRT) in an old computer monitor or television set. It is caused by cumulative non-uniform use of the screen.

One way to combat screen burn-in was the use of screensavers, which would move an image around to ensure that no one area of the screen remained illuminated for too long.

With phosphor-based electronic displays (for example CRT-type computer monitors, oscilloscope screens or plasma displays), non-uniform use of specific areas, such as prolonged display of non-moving images (text or graphics), repetitive contents in gaming graphics, or certain broadcasts with tickers and flags, can create a permanent ghost-like image of these objects or otherwise degrade image quality. This is because the phosphor compounds which emit light to produce images lose their luminance with use. This wear results in uneven light output over time, and in severe cases can create a ghost image of previous content. Even if ghost images are not recognizable, the effects of screen burn are an immediate and continual degradation of image quality.

The length of time required for noticeable screen burn to develop varies due to many factors, ranging from the quality of the phosphors employed, to the degree of non-uniformity of sub-pixel use. It can take as little as a few weeks for noticeable ghosting to set in, especially if the screen displays a certain image (example: a menu bar at the top or bottom of the screen) constantly and displays it continually over time. In the rare case when horizontal or vertical deflection circuits fail, all output energy is concentrated to a vertical or horizontal line on the display which causes almost instant screen burn.

Screen burn on an amber CRT computer monitor. Note that there are two separate burned-in images: one of a spreadsheet program, and another of an ASCII-art welcome screen.

Phosphor burn-in is particularly prevalent with monochromatic CRT screens, such as the amber or green monochrome monitors common on older computer systems and dumb terminal stations. This is partly because those screens displayed mostly non-moving images, and at one intensity: fully on. Yellow screens are more susceptible than either green or white screens because the yellow phosphor is less efficient and thus requires a higher beam current. Color screens, by contrast, use three separate phosphors (red, green, and blue), mixed in varying intensities to achieve specific colors, and in typical usage patterns such as "traditional" TV viewing (non-gaming, non-converged TV usage, non-Internet browsing, broadcasts without tickers or flags, no prolonged or permanent letterboxing) are used for operations where colors and on-screen object placement approach uniformity.

Modern CRT displays are less susceptible than older CRTs prior to the 1960s because they have a layer of aluminum behind the phosphor which offers some protection. The aluminum layer was provided to reflect more light from the phosphor towards the viewer. As a bonus, the aluminum layer also prevented ion burn of the phosphor and the ion trap, common to older monochrome televisions, was no longer required.

In the case of LCDs, the physics of burn-in are different than plasma and OLED, which develop burn-in from luminance degradation of the light-emitting pixels. For LCDs, burn-in develops in some cases because pixels permanently lose their ability to return to their relaxed state after a continued static use profile. In most typical usage profiles, this image persistence in LCD is only transient.

Both plasma-type and LCD-type displays exhibit a similar phenomenon called transient image persistence, which is similar to screen burn but is not permanent. In the case of plasma-type displays, transient image persistence is caused by charge build-up in the pixel cells (not cumulative luminance degradation as with burn-in), which can be seen sometimes when a bright image that was set against a dark background is replaced by a dark background only; this image retention is usually released once a typical-brightness image is displayed and does not inhibit the display"s typical viewing image quality.

Screensavers derive their name from their original purpose, which was an active method of attempting to stave off screen burn. By ensuring that no pixel or group of pixels was left displaying a static image for extended periods of time, phosphor luminosity was preserved. Modern screensavers can turn off the screen when not in use.

In many cases, the use of a screensaver is impractical. Most plasma-type display manufacturers include methods for reducing the rate of burn-in by moving the image slightly,Android Wear watches with OLED displays can request that Android Wear enable "burn protection techniques" that periodically shift the contents of the screen by a few pixels.

Other examples: Apple"s iPhone X and Samsung"s Galaxy series both mitigate or delay the onset of burn-in by shifting the pixels every minute or so for the battery, Wi-Fi, location, and service bars. Also, parallax scrolling may be enabled for the home screen to give icons a 3D-like effect, a setting Apple refers to as "perspective zoom". AG Neovo patented Anti-burn-in technology is also using pixel shifting to activate the pixels to move by the designed time interval to prevent burn in effect on LCD monitors.

Google requests that when these techniques are enabled, watch face developers do not use large blocks of pixels so that different pixels are burned in with each shift, reducing the overall wear of the pixels.

Some screensavers move around, such as those on DVD players or those on some television sets that move around paused video after a long period of inactivity.

Depending on the type of screen, it is sometimes possible to remedy screen burn-in through the use of remedial software and remedial devices. In the case of OLED screens on Android phones, burn-in reduction apps can display an inverted image of the navigation and status bars (which are constantly displayed and therefore the most likely elements to be burned in) to burn in opposite pattern, resulting in a screen whose sub-pixels have more even luminosity and therefore less visible burn-in artifacts.

The most prevalent burn-in image on early televisions was said to be that of the RCA Indian-head test pattern, which would often follow the formal television station sign-off. This was due to the viewer leaving the television set on at the end of the day, which was not recommended by the television manufacturers.

If you"ve ever left your LCD monitor on a single static screen for an extended period, say 24 hours or more, and then changed the on-screen image and seen a "ghost" of the previous screen, you"ve experienced Image Persistence. You can also sometimes see this phenomenon while traveling through an airport and seeing the flight status monitors. The good news is that the persistence is not permanent, unlike previous technologies such as plasma displays or CRTs.

The previous technologies of plasma displays and CRTs are phosphor-based, and extended static images create a "burn-in" that affects the properties of the phosphor material and create permanent damage. The damage is called burn-in, whereas static image "ghosts" on an LCD are Image Persistence. Image Persistence is not permanent damage and is reversible. Modern LCDs include design, driver ICs and chemical improvements that minimize these effects.

Image persistence can happen with any LCD panel, and almost all specifications will have some reference to image persistence. Many will have a specific criterion of acceptable levels of it.

To understand why image persistence happens, we must first understand the basic structure of an LCD TFT. Within the TFT, a voltage is applied to the liquid crystal material to align or twist the crystals in each pixel to allow light to pass through or block light, thus creating the on-screen image. By allowing a static image to remain on screen for an extended duration, the polarity of that voltage on the crystals remains. During this time, ions within the liquid crystal fluid will migrate to either the + or – electrode of the transistor (source or drain). As these ions accumulate on the electrodes, the voltage applied to the crystals to align or twist is no longer sufficient to completely change the image on-screen, resulting in a "ghost effect" from the previous image.

The best method for preventing Image Persistence is to avoid having any static images on the screen for an extended time. If the image changes periodically, the ion flow will never have an opportunity to accumulate on any internal electrode. However, depending upon the use of the display, it is not always possible to avoid static images on the screen. In cases such as these, there are steps that you can do to reduce the chance of persistence.

Switching off the displayduring periods of inactivity (sleeping mode) and arousing at necessary image changes would also be reflected as a positive side effect providing lower power consumption.

Panel manufacturers specifically test for the phenomenon and have designed the TFT cell and improved the purity of the liquid crystal fluid to minimize any effect of image persistence.

Screen burn, a term derived from old CRT (cathode-ray tube) technology — and the reason for a vast industry of decorative screen savers — describes the phenomenon of image retention, otherwise known as persistence, ghost images, blurred images, artifacts, or after-images that linger on your smartphone screen after the original image is long gone. These can mar screen readability and coloration over time and can diminish your smartphone experience.

On mobile devices, screen burn is identified most often on AMOLED or OLED screens, and even then, it’s pretty rare on newer smartphones. It happens when users leave an image on their screen for too long, causing the pixels to struggle when switching to a different color. This may happen more easily with blue colors, but can occur with any image that’s left on screen too long, especially in the brightest setting. Screen burn also may be permanent and considered a display hardware defect as opposed to a software graphics or display driver issue. For screen burn on your mobile devices, there are a few things you can do to fix the issue and, even better, prevent it from happening. Here are a few simple steps you can take.

This is the simplest solution and is frequently effective, especially when you catch image retention early on and want to fix it fast. Turn your phone off entirely, powering it down fully, and let it rest for a couple of hours. If the screen burn issue is minor, this gives the pixels enough time to recover, diminishing after-images, so your phone screen will look fresh when you power back on. This is one advantage of the versatile organic pixel layer used in OLED-based screens, which can correct itself more easily than pixels of the past.

If turning your mobile device off for a while doesn’t fully resolve your issue, a good next option to try is re-training the pixels on your screen to get them back into balance. The good news is, there are apps for that. For Android devices, the Google Play Store has a robustcollection of screen correctors and testersincludingOLED Saver. If you have an iOS device, then you can use an app likeDoctor OLED X instead. This app cycles your pixels through multiple colors and brightness levels, working towards resetting them.

If you don’t want to download an app, you can try checking out theScreenBurnFixerwebsite. It features a collection of videos with color slides and checkered patterns designed to help get your pixels back on track. Run a few of these and see if they fix your pixel problem.

You can be proactive about avoiding or mitigating screen burns on your mobile hardware by modifying various settings you might not have realized could help you. Make sure you are following guidelines like these:

Lower brightness settings:The higher the brightness setting, the harder your OLED pixels have to work, which can cause screen burn. If your mobile device is permanently set on a higher brightness, switch it to auto-brightness or a lower brightness level to prevent problems. For iOS 14, go toSettings > Display & Brightnessand toggle on theAutomaticsetting. TheOptions, True Tone,andNight Shiftsettings also help to modulate excessive brightness and prevent burn-in. On Android, go toSettings > Display > Brightness slideror toggle onAutoto automatically adjust brightness.

Set lock screen and sleep timers:Smartphones come equipped with automatic timers for locking and going into sleep mode, both of which turn off the screen after it hasn’t been used in a while. Make sure these settings are turned on and set to a minute or so. If you haven’t looked at your phone in one minute, it’s probably fine for it to shut off the screen and lock. This essentially prevents image retention because the screen won’t stay on long enough for it to happen. For iOS 14, go toSettings > Display & Brightness >Auto-Lockand choose which time interval you want. On Android 10, go toSettings > Display > Screen timeoutand choose the interval you want.

Get rid of menu, status, and navigation bars:Image retention can happen when you are actively using an app that has a permanent bar for tools or notifications, like when you’re playing a game or watching a movie, for example. When these bars don’t disappear, they cause screen burn after long sessions. Look for options to hide these icons and tools after a moment so they aren’t always present. Immersive modes for your mobile OS will also do this.

Enable dark mode:While it’s not a guarantee against image retention, using dark mode on your mobile device can help reduce the risk, particularly when it comes to overusing brightness levels. You can also try choosing dark keyboard skins. Enable Dark mode in iOS 14 withSettings > Display & Brightness > Darkor use theOptionsfeature to set a timer. On Android, go toSettings > Display > Night modeorComfort viewor set a schedule for either feature.

Screen burn can also become a problem on LCD mobile screens. While this may be a rare occurrence, it’s not impossible either. When it does, fixing it is a lot more of a challenge, since LCD pixels work differently from OLED screens. Therefore, you might have to accept that screen burns on your LCD screen are most likely there to stay. But before you give upall hope, you should still tryusing LCD Burn-In Wiper, whichcycles colors similar to its OLED counterpart to try to repair pixels.

Your last resort after failing to rectify screen burns with the previously mentioned methods would be to see if your device is under warranty so that you can switch out your screen or have it repaired by a professional.

LCD and OLED monitors are most vulnerable to screen burn when new, so you may want to avoid leaving the same image up for too long during the first 100 hours of use

Image retention on a phone display or computer monitor is mostly an issue for devices that display static content or are used for video gameplay with a heads-up display. Unlike with old CRT devices where the phosphor compounds would degrade over time, the “permanent” stationary object or remnant of a picture on an LCD monitor is usually a form of transient image persistence. Here’s how you can fix it and get your high-performing computer monitor back up and running.

While screen burn and image retention are often used interchangeably they’re not quite the same thing. Image retention is a temporary “ghost image” that you can usually get rid of, while “screen burn” means some of the screen’s pixels are “burned out” and it is more difficult to fix, typically requiring hardware repairs, as it’s a more complicated monitor display problem to repair. Obviously it’s not the most convenient problem to have, especially if it’s happening on your best 32-inch gaming monitor, but there are ways to test it, mitigate it, and potentially resolve it

OLED screens are the favored choice for new smartphones and high-resolution TVs, but this type of screen is more susceptible to image retention than LCD screens. Irregular pixel usage can cause noticeable discoloration over a long period of time, typically of static elements like navigation buttons or news station logos. That said, screen burn-in is preventable and for most users should not deter the purchase of a new OLED monitor.

The reason for OLED screens’ being more vulnerable to screen burn-in has to do with the different lifespans and energy demands of different colored pixels. Blue pixels use more energy and tend to wear out faster, which contributes to the ghosting effect of burned-in images. Still, ghost images are generally only an issue for use cases involving static image elements displayed at full brightness for a long time. Also, double-check your warranty and/or computer insurance if you can get professional help for fixing image retention. You might even have coverage through your property insurance, and we have guides on explaining if, for example, your homeowners insurance can cover a computer.

If you’re not sure whether you have screen burn on your device, you can run a screen burn test. Several apps for Android and iOS devices help test for screen burn. Typically this involves displaying one primary color at a time at varying brightness on the device’s LCD screen.

These tips should help get rid of ghost images caused by image retention on modern LCD screens and OLED devices like smartphones, tablets, TVs, and laptops. Image persistence on LCD displays is generally more fixable than “burn-in” on a CRT monitor or AMOLED screen.

Sometimes you can fix a seemingly permanent ghost-like image on an LCD by turning the device off and then turning it back on again after several hours. Try colorful video content or fast-paced videos, or any varied content.

Setting the display brightness to a lower level or enabling auto-brightness if so equipped may reduce the appearance of screen burn or image retention.

Depending on the display technology, you can sometimes fix stuck pixels on a monitor by changing display & brightness settings, choosing dynamic screensavers or adjusting preset picture displays, and turning on auto-brightness. Some software fixes are also available. These typically involve displaying one solid color at a time, which may help get rid of image retention. You may also want to check for “dirty screen effect” and make appropriate adjustments.

On some devices, you can download apps that aim to fix image retention and help reduce the risk of burn-in. To address image persistence on an Android Phone, you can find apps on the Google Play Store that adjust display timeout, play dynamic, all black or moving screensaver images, and even test for burn-in using a white image.

Likewise, for an iPhone, you can visit the App Store for apps that help check your phone for burn-in problems and protect your phone from developing annoying image burn.

On most smart TVs there are some settings you can utilize to reduce the appearance of image retention. LG offers an option called Screen Shift for its OLED TV models, similar to Sony’s Pixel Shift technology, which shifts the image very slightly so as to minimize wear on individual pixels.

In extreme cases where you have dead blocks of pixels or significant degradation of image quality, you may want to opt for display device replacement to remedy screen burn.

There are some easy techniques you can use to help prevent screen burn-in from happening in the first place. The following tips should work on most OLED and LCD screen devices including Android smartphones and tablets, iOS devices, and laptop computers.

Manufacturers recommend keeping brightness at 50% or lower on screens that will be used to display a non-moving picture for more than a few hours at a time.

But these devices do have one drawback: OLED burn-in, sometimes called OLED screen burn. That"s what happens when the outline of an image stays on the screen, leading to discoloration. Fortunately, there are some quick and easy ways to fix it, or at least reduce its effects.

At Asurion, our experts help millions of customers get the most out of their tech, diagnose device problems, and resolve them every day. Here they"ll break down what screen burn is and tell you how to prevent or correct it.

Burn-in is the appearance of a “ghost image" on your TV or phone that won"t go away. It"s caused by the display"s technology. Each individual pixel produces its own light, which gradually dims over time. If an image remains on the screen for many hours, certain pixels get overused and degrade faster, creating discoloration in particular areas. Your screen will still function, but the dark spots can be distracting or annoying.

Some common causes of TV screen burn-in include:Keeping your TV on news or sports network channels that display a static logo or a ticker for a long time - parts of the logo or ticker may burn in

While screen burn-in and image retention appear similar at first, they"re actually very different. Screen burn-in is permanent and will remain whether you change the channel, scroll to a different menu, or turn off your device. With image retention, the discoloration is temporary and will eventually disappear once you switch to a different image or power off.

QLED® TVs use a different technology than OLED TVs and are unlikely to experience burn-in. Samsung® will repair or replace its QLED models if they experience this issue within the first 10 years.

Think your television or smartphone may have burn-in? You can easily check by running a burn-in test, which will play a video that helps you spot discoloration in your screen.

Samsung has a TV burn-in test video on YouTube™ that will work with any brand of TV or phone. It displays a solid red screen; if you notice any other colors, you may have burn-in. There are also videos that cycle through a range of colors to help diagnose the problem.

Tips to prevent OLED screen burn on TV:Reduce the brightness. Keeping your brightness level in the 45–50 range will lower the stress on your TV"s pixels and help prolong their life.

Use the sleep timer. If you doze off in front of the TV, a channel logo or streaming menu could be on your screen for hours, creating a risk for burn-in. This feature will turn off your TV after a set amount of time.

Change the channel periodically. If you"re an avid sports watcher or news viewer, the ticker at the bottom of the screen may cause burn-in without you realizing it. Switching the channel will give those pixels a rest.

Don"t leave your TV paused. This goes for both TV and video games. Pausing a show or game for a long time will cause certain pixels to get overused and eventually become discolored.

Enable screen savers for gaming and streaming devices. If pausing is something you can"t avoid, turning on screen savers will keep the colors on your TV changing and help prevent burn-in.

Burn-in is permanent on your television, but there are a few ways you can try to improve it.Adjust the brightness. Lowering your brightness setting to below 50 could reduce any burn-in. This should also cause any image retention to disappear.

Enable pixel shift. OLED TVs from brands like LG® and Sony® include pixel-shift technology that automatically moves images on the screen to protect pixels from overuse. You can manually turn this on in your settings.

Replace your TV. Unlike phones, you can"t just swap in a new screen on your television. But before buying a new one, check your manufacturer"s warranty to see if it covers burn-in.

If your smartphone has an OLED screen—like the iPhone® 12, Samsung Galaxy® S21, or Google Pixel™ 5—it"s at risk of developing burn-in. However, there are simple steps you can take to protect your device.

Tips to prevent Android and iPhone screen burn-in:Lower the brightness. The brighter your display, the faster the pixels will
