lcd display burn in for sale

“I use a 32-inch LCD TV for my home office display, connected to my PC using HDMI. I also use it for my PS3 and Wii to prevent a Shining ‘all work and no play’-type incident, so it gets quite a lot of use every day. I left town over the weekend and unthinkingly left a fixed image on the display. When I got back, I found that the image had burned in. I thought LCD displays wouldn’t do that, but I was clearly mistaken. The ocean image that was displayed left shadows of the waves across the display. Is there a way to get rid of this problem, or at least minimize it?”

It was a widespread myth for a while that transmissive displays like LCDs weren’t subject to image persistence (a.k.a. burn-in), but it is more accurate to say that they are less subject to burn-in than phosphor-based displays such as CRTs and color plasma. The good news is that on an LCD it can usually be reversed but on a CRT it is usually permanent.

To start, power-down your display for at least 48 hours. If the image is still persistent, try this tip from Lifehacker, which involves using an all-white screen to overwrite the first burn. You could also display static on your screen instead, or make a screensaver that alternates between black and white images.

The theory here is that the rapidly cycling white/black essentially resets the offending parts of the display with stuck pixels. It may take a long time—perhaps a few days—to fade the persistent image away, but it should improve. However, please note that this is not a guaranteed fix.

Another thing you could try: Edge of our Pants has a quick-fix DVD that aids in removing things like screen burn-in, image retention, and even dead pixels. You can either purchase a physical DVD for $10, or a download for $3. can download and burn to a DVD on your side so you don’t have to wait for it to arrive by mail.

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.

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.

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:

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.

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.

TFT LCD image retention we also call it "Burn-in". In CRT displays, this caused the phosphorus to be worn and the patterns to be burnt in to the display. But the term "burn in" is a bit misleading in LCD screen. There is no actual burning or heat involved. When you meet TFT LCD burn in problem, how do you solve it?

Burn in is a noticeable discoloration of ghosting of a previous image on a display. It is caused by the continuons drive of certain pixels more than other pixels. Do you know how does burn in happen?

When driving the TFT LCD display pixels Continously, the slightly unbalanced AC will attract free ions to the pixels internal surface. Those ions act like an addition DC with the AC driving voltage.

Those burn-in fixers, screen fixer software may help. Once the Image Retention happened on a TFT, it may easy to appear again. So we need to take preventive actions to avoid burn in reappearing.

For normal white TFT LCD, white area presenting minimal drive, black area presenting maximum drive. Free ions inside the TFT may are attracted towards the black area (maximum drive area)

When the display content changed to full screen of 128(50%) gray color, all the area are driving at the same level. Those ions are free again after a short time;

Today"s LCD and LED monitors do not suffer from image "burn-in" the way CRT monitors of the past did. Today"s monitors have what is called "image retention" or "image sticking."The best way to avoid image retention is to limit the amount of static content on the display. If possible, turn off the display periodically for a period of time between 24 to 48 hours.To reduce the possibility of image retention, we recommend:• Displaying alternating black/white images for 48 to 72 hours• Power down the unit for a period of time (minimum 24 to 48 hours)• Use a screen saver when the touchmonitor is not in useImage retention caused by static (non-moving) images displayed for lengthy periods is not covered under Elo warranty.

There are two things that make the AMOLED screen to burn-in1) high screen brightness2) static imageDoes the game have static images? Of course - it"s mostly HUD (bag icon in PUBG for example). The higher brightness, the faster the display will wear out. So the key is to play at moderate br...

THANK YOU....and sorry for misbehave wid u but every thing has its reason, i am very angry becoz i already change my screen twice from the date of purchase and ofcourse this really not expected from one plus..

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.

In the TV world, LG has a page that says "It is rare for an average TV consumer to create an environment that could result in burn-in." Nonetheless, stories of OLED burn-in don"t seem rare online, with owners on YouTube, forums and social media reporting the issue. Reviews site RTings has demonstrated burn-in on LG OLED TVs in long-term tests.

So if the fear of the mere possibility of burn-in is your primary concern, the decision is simple: Buy an LCD-based display instead. But know that you"re sacrificing the best picture quality that money can buy. Here are some points to keep in mind:

All things considered, burn-in shouldn"t be a problem for most people. That"s why we at CNET continue to recommend OLED-based TVs, phones and other devices in our reviews. From all of the evidence we"ve seen, burn-in is typically caused by leaving a single, static image element, like a channel logo, onscreen for a very long time, repeatedly.

If you, like most people, watch a variety of content on your TV, phone, or other device with an OLED screen, you"re not going to need to worry about burn-in.

What can you do to prevent burn-in on that new TV? As we mentioned, vary what you watch a bit. In particular, don"t watch something that has the same static areas displayed onscreen, nonstop for days on end.

The logos and news tickers on cable news channels are examples of those static areas -- they have elements that never move, and they remain on screen the entire time you"re watching. That means if you leave your TV running Fox News, CNN, MSNBC or ESPN all day long and don"t watch enough other programming, you"re more likely to get burn-in. Or at least, image retention, which we"ll discuss in a moment. If you play the same game for 8 hours a day, every day, the onscreen status display or HUD is also a likely culprit for burn-in.

To repeat, you can watch those channels, play games or whatever else to use your TV as a TV, your phone as a phone, etc. You just shouldn"t watch only those channels, all day every day. And if that sounds extreme, know that emails I"ve gotten from readers about burn-in always have some variation on "well I only watched that channel for 5 hours a day." If that sounds like you, get an LCD.

As long as you vary what"s displayed, chances are you"ll never experience burn-in. That varied content will age your screen evenly. So in a 24-hour period you watch a movie, play some games, binge some TV shows, they"re all varied enough that you should be fine.

The RTings torture test we mentioned above lasted the equivalent of 5 years of use and they still say "Our stance remains the same, we don"t expect most people who watch varied content without static areas to experience burn-in issues with an OLED TV."

We"ve designed the OLED screen to aim for longevity as much as possible, but OLED displays can experience image retention if subjected to static visuals over a long period of time. However, users can take preventative measures to preserve the screen [by] utilizing features included in the Nintendo Switch systems by default, such as auto-brightness function to prevent the screen from getting too bright, and the auto-sleep function to go into "auto sleep" mode after short periods of time.

Which is to say, Nintendo is fully aware of this potential and took steps to minimize the risk. Also, despite many games having static HUDs, you"d need to play just that one game, for hours upon hours, every day without ever using the screen for anything else, at the highest brightness settings.

Let"s get the descriptions right. Though often used interchangeably, "image retention" and "burn-in" are not the same thing.Image retention is temporary: It goes away in time.

Image retention occurs when parts of an image temporarily "stick" on the screen after that image is gone. Let"s say for an hour you"re looking at a still picture of a white puppy (hey, you do you, we won"t judge). Then you decide to watch a movie. Let"s say Best in Show because you"re keeping with your theme. But as you"re watching you can still see the white puppy image, as if it"s a ghost on the screen, staring at your soul.

You"re not crazy, probably. That"s just an extreme case of image retention. Chances are it will go away on its own as you watch stuff that isn"t the same still image of the puppy.Here"s a section of a 2018 LG C8 OLED TV screen displaying a gray test pattern after 5 hours watching CNN on the brightest (Vivid) mode. They"re the same image, but we"ve circled the section with the logo on the right to highlight it. To see it better, turn up the brightness. In person, it"s more visible in a dark room, but much less visible with moving images as opposed to a test pattern. Since it disappeared after running LG"s Pixel Refresher (see below), this is an example of image retention and not burn-in.Sarah Tew/CNET

Now imagine you leave your TV on for days or weeks instead of hours, showing the same image the whole time. Then you might be in trouble. With image retention, usually just watching something else for a while will make the ghost image disappear. With burn-in, it"s going to remain there for a while. Maybe not forever, but perhaps longer than you"d want.

This is an extreme case, largely just to illustrate what happens. In reality, it"s going to be far more subtle. Watch a lot of the same TV news station, like CNN in the example above? Not sure how your heart can handle that, but let"s say you do. That station"s identifying logo is a prime candidate for image retention and eventually burn-in. Ditto the horizontal borders of the "crawl" on the bottom of the screen.

If you play the same video game for hours and days on end, that game"s persistent scoreboard or heads-up display might burn in. Basically, anything that stays on screen for a long time and doesn"t change can cause image retention and perhaps, eventually, burn-in.

Apple, for one, flags users of OLED-screened iPhones, like the X, 11 and 12, that burn-in is a possibility. Here"s the quote from its support page for the products:With extended long-term use, OLED displays can also show slight visual changes. This is also expected behavior and can include "image persistence" or "burn-in," where the display shows a faint remnant of an image even after a new image appears on the screen. This can occur in more extreme cases such as when the same high contrast image is continuously displayed for prolonged periods of time. We"ve engineered the Super Retina and Super Retina XDR displays to be the best in the industry in reducing the effects of OLED "burn-in."

What"s colloquially called "burn-in" is actually, with OLED, uneven aging. They don"t "burn in" as much as they "burn down." The candle that burns twice as bright burns half as long, right? OLED pixels very, very slowly get dimmer as they"re used. In most cases this isn"t an issue since you"re watching varied content and all the pixels, on average, get used the same amount. But if you"re only watching one thing, that one thing could cause uneven wear. Visually, and in the vernacular, this wear is called "burn-in." Uneven wear is more accurate, but also a lot more syllables.

Also, OLED technology has gotten better. Billions of dollars have been spent on OLED manufacturing and R&D, and that"s ongoing. So stories you may have heard about "burn-in" likely entered the zeitgeist years ago about older OLED displays. You just don"t hear about newer OLEDs having these issues except in extreme situations like those discussed above. You"d likely hear a LOT more stories about OLED now that the two largest phone manufacturers, and many smaller ones, use OLEDs in millions of phones and have for years.

In their warranties, LG and Sony explicitly state that image retention and burn-in are not covered on their OLED TVs. When CNET reached out to LG a couple to ask why, a representative replied:

"There is generally no warranty coverage for image retention by TV companies and display manufacturers. Image retention may result when consumers are out of normal viewing conditions, and most manufacturers do not support warranty for such usage regardless of the type of display," said Tim Alessi, director of new products at LG.

Sony"s reply was similar: "Our warranty covers product and manufacturing defects. Burn-in is not covered as it is caused by consumer usage and is not a product defect."

Neither the iPhone warranty nor AppleCare explicitly mention burn-in, but neither apply to "normal wear and tear," and Apple"s support page above makes clear that it considers burn-in "expected."

When CNET reached out to Samsung for details, the representative defined "normal consumer use" as "use of the product by consumers in a home environment for viewing content and/or gaming in a typical manner. It doesn"t cover business use." In other words, those ESPN logos you see burned into the screens at your local sports bar would not be covered.

Extended warranties don"t typically cover burn-in either. One of the most common, SquareTrade, is available from Amazon, Walmart, and others. They explicitly don"t cover burn-in. However, Best Buy"s Geek Squad Protection Plan might, depending on when you bought it. The latest version only explicitly covers burn-in on phones.

"To avoid the possibility of burn-in, consumers should avoid leaving static images on an OLED screen for long periods of time. For example, leaving a video game paused onscreen for several hours or days," a Sony spokesperson said.

If you notice image retention, don"t panic. Chances are if you watch something different, it will go away on its own after a while. If you"re repeatedly getting image retention of the same thing, then that could be cause for concern.

Pretty much all OLED TVs also have user settings to minimize the chance of uneven wear or burn-in. One is called something like "Screen Shift" (on LGs) or "Pixel Shift" (on Sonys), which moves the image slightly around the screen. They also have built-in screensavers that pop up after extended idle time. You should also enable screen savers on connected devices like game consoles and streamers.

To remove image retention, the TVs can also perform "refreshers" on a daily or longer-term basis. On Sony TVs the feature is called "Panel Refresh," and LG calls it "Pixel Refresher." It can be run manually if you notice image retention or, in the case of LG, you"ll get a reminder to run it after 2,000 hours.

LG also has a Daily Pixel Refresher, which it says "automatically operates when users turn off the TV after watching it for more than four hours in total. For example, if a user watched TV for two hours yesterday and three hours today (more than four hours in total), when powered off the Daily Pixel Refresher will automatically run, deal with potential image retention issues, and reset the operation time. This process will occur when the TV is powered off after every four hours of cumulative use, even if it"s in one sitting."

When it comes to phones I wouldn"t be too concerned, since it"s likely you"ll replace the phone far sooner than any image retention/burn-in issues become bothersome. Regarding my aforementioned S6 Edge, even though I noticed it, I wouldn"t say the burn-in reduced my enjoyment of the phone. I was never watching a video and thinking, "Wow, I can"t enjoy this video because of the burn-in." Since the phone was in use by its second owner twice as long as I had it, and was only let down by its battery, burn-in clearly wasn"t a dealbreaker. My friend replaced it with a Pixel 4a, which also has an OLED screen. So even after 4 years with that screen he still preferred to get a phone with OLED.

With TVs, beyond the methods outlined above, there"s not much you can do to reverse burn-in. In theory, I suppose, you could create an inverse image using Photoshop and run that on your screen for a while. This could age the rest of the panel to more evenly match the "burned in" area. Figuring out how to do this is well beyond the scope of this article, and you"d need to be pretty well versed in Photoshop to even attempt it.

CNET has not conducted any long-term real-world tests of OLED burn-in. In our experience reviewing TVs, we have seen image retention on OLEDs that disappeared quickly, for example after running a series of static test patterns, but nothing permanent.

The most comprehensive independent tests for burn-in on TVs was run by the aforementioned review site RTings. In August 2017 they began a burn-in torture test with LCD and OLED TVs, followed by a "real life" torture test in 2018. They stopped regularly updating the test in 2020, but that was after the equivalent of 5 years of normal use on multiple TVs, and still they felt that most people will never have an issue with burn-in.

Before you check it out, keep in mind what they"re doing is not normal use. You"d have to be trying to wreck a TV to make it look that bad, which is literally what they"re trying to do. That said, the information is still valuable, and the main takeaway is that OLED is indeed more susceptible to burn-in than LCD.

You"ve noticed a ghostly image on your TV or phone screen. If it goes away after a few minutes of watching something else, it"s image retention and it"s probably nothing to worry about. If it "sticks" longer, or you"re repeatedly seeing that same residual image, it"s burn-in. With phones, you"ll likely replace it before the screen becomes an issue.

With OLED TVs, it"s something to keep in mind if you"re a TV news junkie, or only ever play one video game. Keep an eye out for image retention or uneven wear. If you spot it, perhaps switch up your viewing habits, adjust the TV"s settings, or run the pixel refresher a few times. And if you watch content with hours of the same static image each day, or just keep CNN, Fox or CNBC on in the background all day, you should probably get an LCD TV.

If you vary your TV viewing habits like most people, however, it won"t be an issue. Even so, caveat emptor. Or as Caesar himself once said, "Conscientiam autem ardeat sed non anxius" (be aware of burn-in, but not concerned). He was, we hear, a big iPhone fan.

You can follow his exploits on Instagram and his travel video series on YouTube. He also wrote a bestselling sci-fi novel about city-size submarines, along with a sequel.

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.

Alternatively, if you’re trying to get your second monitor working, check out our resource article about how to fix a second monitor not detected error.

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.

One of the biggest things that can affect the value of your phone, besides its cosmetic condition is the battery. Nobody wants to buy a phone that does not last more than a few hours between charges and find themselves frequently tied to a wall socket. As a result, companies that buy phones to refurbish and resell will always test the health of your battery and will likely offer you less if your battery is found to be in poor condition.

It is much more difficult to swap the battery in your phone than it is to handle it properly in the first place. To use an old adage, prevention is better than cure. Most modern devices do not allow users to easily access their batteries as they are sealed units. This also means if you want to replace a battery you would need to use a professional service.

Before we go into details about how to keep your battery at its best, we will look at a few common myths and misconceptions about batteries. Some of these you may have heard or believe yourself, and it is important to separate fact from fiction.

This belief stems from a time when the most common type of rechargeable batteries in mobile devices were Nickel Metal Hydride (NiHM) batteries. Early versions of these batteries had a ?memory effect?. What this meant was that if you did not fully drain the battery before recharging it, and did not then charge it fully, the battery would ?remember? this smaller capacity and not charge properly beyond it. A trick people used to use was to put the battery in the fridge to reset its memory.

These days the battery technology found in mobile phones is Lithium Ion or Li-Ion, and more recently Lithium Polymer. These technologies do not suffer from the memory effect and in fact the opposite advice is best for these batteries. Li-Ion batteries experience the most strain when they are either at 0% or 100%, meaning that it is best to keep the charge as far away from these extremes as possible. While it is not practical to keep your phone at 50% all the time, trying to keep the charge between 20% and 80% is a good way to help maintain your battery?s health.

Modern devices have smart battery management software as standard. When your battery gets to 100% the device will simply stop charging at full power and only trickle charge as and when the phone requires it, keeping the device at 100%. This does not mean however it is a good idea to leave your phone charging overnight as this is indeed bad for your phone, but not for the reasons just stated. We will explain more later.

The reason behind this is a simple case of money. Manufacturers want you to buy their official products as the additional sales lead to additional revenue. You should beware of cheap, poorly made chargers on Amazon or Ebay, however any charger made by a reputable company is perfectly fine to use with your device. You may find that it may not charge as fast for devices that use fast charge technologies, but as we will explain that is not necessarily a bad thing.

One important measurement you can use to determine your battery health is to check the cycle count. A ?cycle? is a discharge and charge of the battery from 0-100%. What do we mean by this? It means that any individual or combination of charges that amounts to 100% of your battery capacity counts as a cycle. Fully charged the device from 0 to 100%? That?s one cycle. Charged it from 20% to 70% (a charge increase of 50%) twice? That?s a cycle too.

Every cycle your battery goes through slightly degrades its health due to chemical and physical breakdown. Apple state for example that after 500 cycles on an iPhone that its battery is rated to have lost approximately 20% of its original capacity. This means 20% less lifespan and more frequent trips to the charger, adding more cycles more often and degrading the battery even quicker.

It is very easy to check your cycle count on an Apple device. Simply go to Settings > Battery > Battery Health and you will see the number of cycles as well as the current capacity as a percentage of its original capacity.

It goes without saying then that reducing the number of cycles your battery goes through should be your aim when trying to extend the life of your battery.

One method to keep your battery in top condition is to limit the stresses on the battery as much as possible. There are many ways to do this, but we will list what are the most practical and easy to achieve. Incorporating these tips in your daily routine will give your battery the best chance at living a long, healthy life.

This might seem like a silly one but turning off your device when it is not being used is a great way to maintain the health of your battery. These days there seems to be few times when we are not glued to our phones, but one time you can guarantee several hours where your phone is not being used is when you are asleep. Turning your phone off at night will significantly reduce the drain on your battery during these hours and reduce how often you must charge it.

If turning off your phone overnight isn?t your cup of tea, consider putting it in to airplane mode instead. Turning off your data connection, Wi-Fi or other connectivity options will save on battery life while your phone is not in use. If you must put your phone away at work this is another good time to put it in airplane mode too. Your phone will simply download any sent messages when you turn airplane mode off and restore your connection, so you don?t have to worry about missing anything.

Just like people, your battery doesn?t like it if the temperatures get too low or high. Whilst they have more tolerance for cold temperatures, the heat can be a real killer. Trying to keep your phone as close to room temperature as possible will help keep your battery in peak condition. That means keeping it out of the blazing sun during summer as much as possible.

This piece of advice relates to the last. Your phone case, dependin
