Screen burn, also called screen burn-in, ghost image, or display burns are images or icons that are displayed on a screen when they should not be there. Screen burn comes on gradually and gets worse over time and is most common on OLED screens. The navigation bar, the top status bar, or home screen apps are frequent images that get  “burned” into the display.

1. You aren’t looking at your phone screen with a white display. Screen burn is easiest to notice on an all-white or blank screen with no icons on it. And it is rare that your phone will display an all-white screen. This is why SmartphonesPLUS uses industry-leading phone diagnosis software and other tools that allow us to see phone screens on an all-white screen, along with other tests, to examine each phone we receive thoroughly.

2. You do not change your home screen layout or background image. You look at the same phone, with the same background every day, and can’t notice the screen burn because the icons and apps on the phone are always in the same position. It is much easier to notice screen burn when you shift the layout of icons and apps on your home screen.

Here’s an example we think relates to screen burn to help explain why it’s not as noticeable: when you see a person every day that is losing weight you don’t notice how much weight they lost, but if you saw a person you haven’t seen in over a year that lost 50 pounds you would notice right away. In the same way, your eyes and mind adjust to the screen burn as it gradually burns into the display over months or years.

Screen burn is caused by pixels displaying the same image or icon for an extended period of time. Static images such as apps, navigation bars, and keyboards can deteriorate pixels in the display from overuse. This causes these over-used pixels to look darker in color than others around them. Certain areas of the screen like status bars are more susceptible to screen burn as they are constantly displaying the same image.

As you can tell from the photos, screen burn can make the display look discolored with darker pink or gray hues. Because of its gradual onset, many users don’t even realize their display has screen burn. If you would like to check for screen burn on your phone, put your phone on a white screen. A white screen will provide contrast making the discolored pixels more noticeable.

Lowering the brightness will lengthen the life of the pixels in your display. Keeping the brightness as low as possible will ensure that screen burn won’t happen as quickly.

Avoid screen savers when your screen times out as they are generally static images that are displayed for a long period of time. Screen savers will cause the pixels of your display to be overworked when you are not even using your device. If you have a phone that uses always on display, make sure to turn this off to prolong the life of your screen’s pixels.

There are some apps and videos out there that claim they can fix screen burn, however, the results tend to be insignificant as it is a hardware issue of the display. The only way to truly fix screen burn is to replace the entire display of the phone. If you’d like to speak with a technician to see the cost of replacing a screen you can make an appointment or contact us.

Image burn-in, also referenced as screen burn-in or ghost image, is a permanent discoloration of sections on an electronic display caused by increasing, non-uniform use of the screen.

The term burn-in dates back to when old monitors using phosphor compounds that emit light to produce images lost their luminance due to severe usage in specific display areas.

Chances are you"ve encountered image burn-in and image retention before, but you didn"t know which one you were seeing. They both have the same visual effects, so it"s easy to mistake them for each other, but there"s one key difference:

Most of the time, these guides explain how image retention works and how you can speed up its recovery process. We want to clear up any confusion you might have about image burn-in and image retention on LCD and OLED displays.

Image retention, also known as ghosting or image persistence, is the temporary effect of images remaining visible on LCDs or OLEDs for a short period, usually a few seconds.

If the images fade away after a short time, you are dealing with temporary image retention. If the images stay permanently, you are dealing with image burn-in.

Image retention doesn"t require any intervention from the user to make it go away – it"ll do that by itself. Retention will often occur before burn-in does on newer display technology like our

using a screen saver, cycling various graphics on the screen to exercise the pixels, and powering off the display whenever possible will help clear the image retention on your display.

These are the same tricks you"ll see advertised as a "cure" for image burn-in, but don"t be fooled. There"s no fix for burn-in, only ways to prolong it from happening.

Before you assume your screen has burn-in damage, try these tips and wait to see if it"s just image retention. Image retention is a harmless and common occurrence on many screens.

Image burn-in is caused by screen pixels that stay activated in a static position for long periods of time.Think of a TV in a lobby or waiting area that"s always playing the same news channel. The news channel footer and logo get burned into the screen permanently, even when you change the channel.

When LCD or OLED pixels stay activated in a static position, they"ll eventually become "stuck" in that position. When this happens, you"ll notice a faded, stubborn image that persists on the screen.

When pixels fail to activate or deactivate entirely, it results in faded images that won"t clear from the screen. This is common in applications using character LCDs where the alphanumeric characters are updated less frequently.

Remember: There"s no way to remove or reduce burn-in after it occurs. If a stubborn image persists for extended periods or after restarting your display, you"re likely dealing with image burn-in.

Even the most advanced displays will experience burn-in at some point, but there are some simple actions you can take to extend your screen"s lifespan before burn-in occurs. With the proper practices, you can get years of outstanding performance from your display without any burn-in effects.

A screensaver is a good alternative if you can"t turn your display off. For displays that don"t need to be ON at all times, it"s helpful to let the screen rest when not in use.

Get those pixels moving! The longer a pixel stays activated in a static position, the closer it gets to being burned in. You can exercise your screen"s pixels with scrolling text, moving images, or changing colors.

For an OLED display, decreasing the contrast will lower the brightness and reduce the rate of image burn. More illumination (brightness) requires more current, which reduces OLED pixel lifespans.

For a LCD display, lowering the contrast will put less stress on the liquid crystals and will help to reduce the rate of pixels becoming weak, or sticking.

Remember that image burn-in is not reversible and can not be fixed once it happens. Whether it is a scrolling effect, rotating pixels, using a screensaver, or turning off the screen when not in use, it"s essential to establish image burn-in preventive measures to help extend the lifespan of your display.

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.

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.

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.

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.

Whether you’re using a laptop, netbook, tower, or tablet, if you’re connected to separate peripherals (such as a docking station, monitor, or printer) you’re probably costing your employer more money than you have to. It is very important to know how to avoid screen burn.

Many office users fail to power down their peripherals at the end of the working day, and this causes undue power usage throughout the evening. Consider powering down all of your peripherals at the end of the day to conserve energy costs.

Separate monitors, for example, have no impact on the computer systems they’re attached to. No IT department in the world would ever ask you not to turn off a separate monitor, and you really should for two reasons: one, to conserve power, and two, to avoid screen burn.

“Screensaver” application were designed for computer users that couldn’t turn off their computers. They display a changing set of images so that phosphorus dots on older monitors did not become over- or under-energized by having the same ‘dots’ active for long periods of time.

Once the ‘screensaver’ was firmly entrenched in the user-space, it became a matter of habit to activate and use it as a justification for not powering down, but with the invention of LCD and other non-phosphorous based imaging devices, the need for a screensaver has completely vanished.

While older, phosphorous based CRT monitors could experience ‘screen burn’ from as little as 3-5 days of constant exposure to the same output, more modern LCD screens can experience several weeks’ worth of continuous stimulation without experiencing ‘screen burn’. But, they still draw power when they’re on. And many draw power, even in the ‘standby’ mode that may be programmed into them by either the computer they’re attached to, or by the manufacturer. This allows them to return to a working state very quickly, but with a constant, low power draw. Turning them off delays return to a fully functional state by a mere few seconds, at most, and requires less power than leaving them in standby mode overnight.

It’s more than worth it to turn off your peripheral monitor at the end of the day, and simple to do so. From our experience, we’ve learned that’s how to avoid screen burn. Just press that little circle with the dash in it on the front of the monitor and walk away. Your screen will appreciate you, and your boss will appreciate you trying to save him some money, and the environment.

Manufacturers are well aware of the issue and are implementing software solutions to avoid screen burn-ins. Luckily there are tricks to increase the lifespan of your OLED:

Navigate to your Settings menu and tap "Display". We"d recommend turning the auto-brightness mode on, so when you"re indoors or outdoors the phone will automatically adjust the screen brightness for optimal use and won"t have your screen brightness maxed out at all times.

The less your screen stays on inactive, the longer the lifetime of your display. So while you"re in the Display Settings menu, shorten your screen timeout to a convenient minimum. Most phones allow you to decrease to 15 seconds of inactivity.

The Immersive Mode hides static icons of the notification bar providing a burn-in preventive treatment. We"d recommend using this mode where available.

Our advice is to go with solid colours and change your wallpaper occasionally. For example, a solid black wallpaper. OLED screens consume energy and when displays are black the OLEDs do not burn in. Additionally, solid coloured wallpapers will contribute to longer battery life overall, so it"s a win-win.

If your phone has suffered from burn-in you"re wondering if you can fix it, unfortunately you can"t. However, thanks to some very talented developers, there are apps to solve this issue. The science behind these apps is that your pixels can "exercise" and make your burn-in disappear (but you won"t get rid of the burn-in completely).

These burn-in fixer apps are pretty clever. Devices running Android Lollipop or later have something called "Inverted Colours", and the fixer app takes advantage of this software trick.

When installing the app, it will run diagnostics to identify if your screen has burn-in and parts of user interface will be hidden to stop burn-in progressing. Colours will be inverted underneath the burn-in to clear the visibility of the damage. Most of these apps are on Google Play and some of them have a star rating above 4.0.

HUGE MASSIVE DISCLAIMER... Some users report permanent screen damage after using these tools, so use with caution only if you"re on to the last resort of buying a new screen anyway.

All OLED screens can and will burn-in and they"re more exposed to burn-ins than standard LCD, however LCDs are not completely free of this bug. However, OLED screens produce better image quality than LCD screens. So when you choose a phone, that"s a price you pay- a shorter display lifespan for better image quality.

Unfortunately, it"s quite tricky to spot a burn-in with an untrained eye or professional equipment, therefore when recycling your phone, you might quite easily be unaware your phone has this issue. When your device has been sent off and a recycler performs their inspections, burn-in specific tests will take place and you will be notified of the results. If your device has suffered from burn-in, your quote will be most likely be downgraded to the "Broken" price category. So, before it"s too late, start following the tips we"ve discussed above to enjoy your displays for longer.

I am developing a user interface on a cheap Kinco color LCD HMI unit. After leaving a test UI on the screen for about 3 days, there was a very decided "ghosting" effect.

I was able to eliminate the ghost outlines by alternating a solid black and white screen over the course of about 2 days. Now the screen is back to normal and the ghosted image does not appear.

Since this HMI will be in service for several years with basically the same screens always in use, I want to build a screen-saver which will prevent ghosting. Note that users will view/interact with the HMI very little, as it"s in a remote location and may be visited a couple times per week.

In building a screen saver, should the display constantly alternate between solid black and white screens, or is there a specific color which places the least "strain" on an LCD pixel, which would avoid ghosting and ensure pixels remain as bright and color-accurate as possible? For example, is Black considered "full on" or "full off" by the LCD circuitry and pixels? Would a black or white pixel create more prominent ghost image, or is the issue going to appear for any pixel that does not change over a period of time?

At this point I don"t know whether alternating between colors is better or worse than filling the screen with a single, unchanging color. I"m looking to implement whichever scheme preserves the pixel brightness/dynamic response and eliminates ghosting.

Ever had your TV showing nothing but a black screen even if the audio was working? Unfortunately, that’s a common issue with low/middle-end LCD/LED TVs these days… Even more frustrating, this issue often comes from a rather tiny and cheap component that can be easily replaced. Most common issues are:

The first step into repair is to find the root cause of the issue. As backlight failure is a very common issue, this is the first thing to test. To do so, the easiest way is to power on your screen, put a flashlight very close to it and check if you can see the image through. The image would be very dark, like turning the brightness of the screen very very low.

That implies disassembling the TV to access the backlight which is between the LCD screen in the front and the boards in the rear. In my case, with a Samsung F5000, I had to process as follows:

First we have to remove the back housing to reveal the boards (from left to right: main board, T-CON, power supply) and disconnect the LCD panel from the T-CON board.

Note: Older TVs have neon tubes for backlight, which is thicker and less exposed to this kind of failure. LED backlight is the most common thing these days, but do not mistake an LED TV with an OLED TV. The first one is a classic LCD panel with a LED backlight, whereas the second is an OLED panel that doesn’t need any backlight as it is integrated in each pixels (making the spare parts much more expensive by the way).

As we can see, the backlight system is made of 5 LED strips. First thing to do is look for burnt LEDs. Most LED backlight systems have strips set in series, meaning that if one of the them fails, all the system goes dark…

Using a multimeter, we can confirm that the strips are indeed set in series, so now we have to test each strip individually. Professionals use LED testers such as this one (about 40$ on amazon) but as I didn’t had one at the time, I decided to make one, McGyver style!
