Also worth noting here is that LG introduced a new feature for its 2018 OLED TVs that can dim the brightness of static picture elements without impacting the rest of the picture.

After a drop, vertical lines may indicate internal damage. Try softly pressing on the display or restarting the phone. If lines persist, a professional repair may be necessary.

This Sony warning is followed by a strikingly extensive list of examples of the sort of material that can cause image retention, and an even longer list of steps you should take to reduce the risk of it.

Set the picture settings based on the ambient conditions. The Standard Picture is recommended for home use and when viewing content that often displays the station logos, etc.”

Next, LG also upset buyers of its 2018 OLED TVs recently by releasing a new firmware update to its most recent generation of OLED TVs that increased the extent and speed with which bright images were dimmed down (as covered here). LG has confirmed to me that this ‘intended to reduce consumer discomfort in situations where temporary image retention can occur in certain viewing conditions’.

(i) Increased brightness can affect the likelihood of long-term image retention, and LG is working on improving its algorithm to reduce the correlation between brightness and image retention. This includes reducing the image retention risk, while keeping the optimal brightness as intended. Toward this end, there are already a number of technologies built into LG OLED TVs including:

This is an article I’ve considered writing numerous times over the past few years, but have always eventually shied away from. Mostly on the grounds that I just haven’t been persuaded that there was enough cold, hard proof out there that consumer OLED TV screen burn - where persistent exposure to bright, static image elements can ‘wear out’ areas of an OLED screen’s organic materials faster than the rest of the screen, leaving permanent ghostly traces of static image elements behind - was truly that widespread a problem.

Determining if the issue is software or hardware related is a crucial step. Restart your phone to see if the lines disappear, indicating a possible software glitch. If the issue persists, especially on the startup screen, it’s more likely a hardware failure. In the case of hardware issues, professional repair is often necessary.

The main point is that every pixel in an OLED screen makes its own light, whereas LCD TVs have to share external lights across whole sections of pixels. This means a shot’s brightest pixel right can sit right alongside its darkest one on an OLED screen with no compromise to either the intensity of the bright pixel or the blackness of the dark pixel. As a result, OLED screens can deliver deeper blacks and peerless local contrast, especially in scenes that contain a mix of dark and light content.

What’s more, all of this user responsibility applies in the context of OLED TV warranties not covering potential damage due to screen burn, since if it occurs, it is considered to have been the TV users’ fault…

First, Sony upset owners of its OLED TVs earlier in the year (as reported here) by introducing via firmware a new picture dimming algorithm that kicked in distractingly aggressively if a static image component - such as a gaming HUD - was onscreen for around a minute. Sony confirmed that this was a deliberate move. And while the brand has since tweaked the update to make it less distracting, the point behind it was surely an attempt to minimize the risk of screen burn affecting its OLED TVs.

It should be said that a further section in Sony’s OLED Manual discussing the Panel Refresh and Pixel Shift features the TVs provide to combat burn in defuses things a bit. But the burden of responsibility on the user to minimize potential OLED screen burn nonetheless feels pretty high.

LG have noted Rtings’ new testing process which is a step closer to typical real-life viewing patterns. LG is aware of the concerns regarding after image in stress usage and continues to work on developing technologies to prevent image retention in more diverse viewing conditions.

I guess this situation could change given that OLED’s popularity is a relatively recent phenomenon, as this places a limit on the time where screen burn has chance to establish itself. But right now it doesn’t seem to be affecting too many people. Despite how many OLED TVs have been sold over the past two-three years.

The Sony A8F recently received a firmware update that introduced extra dimming when static objects... [+] were detected. Much to the annoyance of some of the TV's owners.

Rtings has acknowledged that its 2017 OLED TV tests were conducted using extreme conditions, not at all representative of typical OLED TV viewing or usage habits.

The cause of these lines can vary from software issues (rare) to potentially hardware failure (more common). Before seeking professional help, you can try a few fixes yourself like restarting your phone, updating your operating system, and checking to see if there’s any physical damage along the screen on side of the phone. Sometimes you can simply wait out the issue as well to see if it goes away; but if it doesn’t, you’ll have to make the decision to either have it repaired or change your phone.

Another relatively recent development that’s made raised screen burn’s profile of late is the most recent test for the problem by online tech testing site, Rtings.

(ii) There are two ways to increase the brightness of OLED pixel: Increase the amount of current to OLED pixel (increase the brightness of the light source), or improve the aperture ratio (increase the size of the 'window' that passes through the light source).

This made me think that either Sony was reacting to actual cases of screen burn in their own test environments or actual consumer reports, or else they were acting on advice from LG Display, the manufacturer responsible for pretty much all the world’s TV-sized OLED panels.

So after this experience I couldn’t help but wonder a) how much longer the TV would have had to be exposed to the Mad Max imagery before the image retention became permanent burn in, and b) what damage I might have been doing to the screen (permanent aging of all the organic material, perhaps?) if I’d subsequently had to run the Pixel Refresher feature repeatedly in much less than a year.

* How the Pixel Refresher works, in LG’s own words: “There are two anti-image retention systems incorporated into LG OLED TVs, the short-term Pixel Refresher and the long-term Pixel Refresher.

Lines on your phone screen can manifest as horizontal, vertical, or even as black, white, or green streaks. These are indicators that something isn’t working correctly. A single green or white line might be a pixel row that’s stuck on, while multiple lines suggest a more serious problem.

The good news is that I managed to remove this ghosting using the TV’s Pixel Refresh feature (explained below the main article). The bad news is that Sony’s advice on its own similar Panel Refresh feature states that ‘The Panel refresh function may affect the panel. As a reference… do not perform it more than once a year, as it may affect the usable life of the panel.”

So what can we make of all this wealth of evidence for both sides of the argument? Well, first I don’t think there can be any doubt that OLED TVs are still susceptible to permanent screen burn. It is not just a ‘historical’ problem that has been completely ‘solved’. In fact, LG itself admits in some of its comments that burn-in has at least the potential to be more of a problem now, as the arrival of HDR sees a push towards higher brightness.

Remember, if you’re not comfortable with these steps or if the problem persists, seeking help from a qualified service center or repair professional is recommended.

OLED TV‘s are susceptible to image retention (burn-in) due to the characteristics of the materials used. Image retention may occur if images are displayed in the same location on the screen repeatedly or over extended periods of time. This is not a malfunction of the TV. Avoid displaying images that may cause image retention.”

There is also an upside to this firmware update situation, of course, in that screen burn-related TV features can always be refined and improved over time. And I feel confident given the pedigree of the brands involved that there will indeed be steady, generally upward progress.

On the manufacturers’ side, this means deploying anti-screen burn picture measures that can affect picture quality. Measures which consumers should remember are regularly added to OLED TVs via firmware updates after the sets have been launched and initial reviews have been written.

The long-term Pixel Refresher operates when the TV reaches an accumulated viewing time of more than 2,000 hours. At this point, when the user switches the TV off, a notification appears informing them that the Pixel Refresher will start. This operation runs for an hour while the TV is off. A white horizontal line displays onscreen when the process is almost finished. If users turn on the TV before the 1-hour operation has concluded, the TV will show a message that the Pixel Refresher has not been completed. This notification will display each time the TV is turned off, until the Pixel Refresher has run its full course. Additionally, users can manually activate the Pixel Refresher via the TV’s menu whenever they choose. However, it is not necessary for them to do so as LG OLED TV automatically runs the long-term Pixel Refresher each time 2,000 hours of viewing is reached.”

Perhaps the single most important point the defense side of this debate needs to consider is why OLED TVs are so sought after by many discerning AV fans.

All of these measures suggest that screen burn is indeed still considered to be an issue by OLED TV makers. In fact, with such new anti-retention/anti-screen burn measures seeming to appear increasingly often in recent times when OLED TVs have been around for years, it’s hard not to think that the flurry of activity has something to do with the growing influence of high dynamic range video (which delivers a much wider brightness range) and the resulting need to make OLED TVs run more brightly.

Personally I think OLED and LCD TVs have pros and cons that give each of them specific advantages in different environments and with different sorts of content. There is absolutely no doubt, though, that OLED TVs can and do deliver pictures so glorious that many serious AV fans may well consider the risks of screen burn - and the efforts required to avoid it - a relatively small price to pay.

I used the OLED77C8 in many head to head tests against other TVs over the course of a few months, using many of the same high dynamic range movie sequences. Especially the extremely bright Mad Max: Fury Road 4K Blu-ray. And just before the set was finally due to go back to LG, I noticed a number of areas on the screen that showed ghostly shadows of the 4K Blu-ray’s header image. These ghosts remained visible following a number of power off/on recycles.

There are inevitable qualifications to this number, based around how much you watch TV content with static image areas, how brightly you run the TV, and even the colors of the static picture elements (with OLED red seeming to degrade faster than other tones). OLED screens which Rtings is running at a low brightness or without showing content for any extended amount of time that has static image elements are running beyond 5,000 hours without evidence of permanent burn-in issues.

DIY fixes for an iPhone include resetting the phone, tapping the screen gently if it’s a loose connection issue, or trying a hard reboot.

Also, of course, while the OLED TV makers’ efforts to avoid screen burn by manipulating the picture might not always go down well with OLED TV owners, they’re well intentioned, and show that the OLED TV brands can hardly be accused of ignoring the problem. They’re seemingly constantly engaged in trying to find/improve ways of reducing the risk of OLED TVs falling prey to permanent burn in.

Yes, minor lines caused by software issues can sometimes be fixed at home. Start with a simple restart or factory reset. If the problem is hardware-related, more advanced repair steps may require professional assistance.

A number of recent developments, though, have made me think the time is right to explore this controversial issue. I present all of these recent developments here as, I guess, the evidence for the prosecution.

Also recent improvements in the aperture ratio have enabled OLED TVs to increase the brightness without increasing the current passing through the light sources (so again with no compromise in panel life span).”

Screen issues on phones can be frustrating. Here we address common queries to help resolve these unwelcome glitches quickly.

OLED’s self emissive nature also means that its pictures hold up from wider viewing angles than those of LCD sets. These advantages have made OLED TVs firm favorites with many movie fans and TV reviewers.

The instruction manuals you get with every OLED TV include statements explaining first that image retention is an issue for OLED TVs, and second, what precautions you should take as the TV owner to avoid image retention happening. For instance, there’s this in the manual for Sony’s A1 OLED TV:

Also important to stress is that the sort of varied TV usage associated with most typical household viewing patterns naturally works against permanent screen burn occurring. Most evidence so far suggests that only people who spend a higher than usual amount of time watching channels or playing games with static image elements really need to worry about it.

The final recent incident that prompted me to put this article together was that I actually experienced myself extended image retention (where ghosts of prominent image elements remained even after I’d powered down the TV) on a 2018 LG OLED77C8 OLED TV.

When the current is driven through the OLED material, which is equivalent to each subpixel, it generates light. In this process, the brightness increases in accordance with the amount of current applied per unit area - which does add to the stress that OLED pixels get. However, thanks to improvements in OLED material technology, the current that OLED pixel can bear has been increased, which means no compromise in life span.

Dropping a Samsung phone can jar internal connections or harm the screen. This physical damage can lead to lines on the display.

These qualifications, though, really just tie in with the screen burn avoidance advice provided by the OLED TV brands (more on this presently). So what really catches your eye about the Rtings research is how quickly burn-in could occur if you don’t follow that screen burn advice.

It also seems to me, though, that between the ever-increasing efforts of the OLED TV brands to find ways of reducing the chance of screen burn occurring, and the willingness of devoted OLED TV fans to take care with how they use their TV, occurrences of permanent screen burn in the real consumer world are now and will continue to be rare. Despite how many OLED TVs are being sold these days.

Starting in 2018, Rtings introduced a new criteria for evaluation, which comes closer to actual consumer usage patterns and includes several test programming such as NBC, FIFA Football, CNN, NFL Sports and the Call of Duty video game, with tests for each channel performed repeatedly every day for 20 hours.

• Turn off the OSD (On Screen Display) by pressing the / button, and turn off the menus from connected equipment. For details, refer to the instruction manuals for the connected equipment.

What you do need to at least be aware of, though, is the impact on your viewing of the processes involved with ensuring that screen burn doesn’t happen.

This paragraph from Sony actually conflates image retention with burn-in, backing up my sense that while they’re not exactly the same, they’re not entirely unconnected either, at least to the extent that much of the sort of image content that causes image retention has the potential to lead to screen burn. Though I should stress that LG makes a counter argument in the second half of this article.

-    Logo Extraction Algorithm which can detect a fixed logo, such as a network logo on a screen and reduce the brightness of the logo.

I seem to remember similar guidelines being rolled out back in plasma TV days, though. Yet here we are today, still faced with all manner of obtrusive channel logos.

OLED is a self-emissive technology which brings many significant benefits to image quality and performance. As with any self-emitting display, OLED TVs may experience temporary image retention under certain conditions, but permanent image retention, or burn-in, is rare under normal viewing conditions.

Perhaps tellingly, there seems much more chatter about the occasionally invasive procedures TV makers introduce to counter screen burn than there is about actual screen burn occurring.

Ah yes. Usage advice. This is another key aspect of the any discussion of OLED screen burn, with implications for both sides of the ‘how much should you worry about it’ argument.

Although it’s a long read, I think it’s worth reproducing this information in full here, as this is public domain information written by an OLED TV brand that arguably shows how concerned OLED manufacturers are about the risks of screen burn. So here goes:

LG continues to lead the market in large screen OLED products, which undergo rigorous quality control measures to ensure that they offer durability, reliability and extremely high consumer satisfaction. In addition to strict quality control measures, LG continues to develop technologies to prevent image retention such as the Pixel Refresher*.

In putting together a case for the defense, the first point to raise is that even though OLED TVs have become vastly more popular over the past three years, it doesn’t seem as if technology forums across the globe are awash with complaints of permanent screen burn.

Important Note: If your phone is under warranty, contact the manufacturer or retailer for repair options before attempting fixes yourself.

Having sorted that out, let’s get to why I think OLED’s potential susceptibility to screen burn warrants looking at now more than it has before.

The rest of the defense case comes from LG. LG is pretty much single-handedly responsible for making OLED TVs mainstream, so I sent a series of questions to it on the subject of burn in. The Korean brand’s laudably extensive replies are published in full below:

There is it seems to me a connection between image retention and screen burn, to the extent that image elements that cause image retention can lead eventually to screen burn. You could even see image retention as a warning that something you’re watching a lot could eventually lead to screen burn, and so needs to be handled with extra care (more on this later). But the two are not the same in either their cause or the permanency of their effect.

LG OLED TVs were always designed to meet the same lifespan standard level as other TV categories. In actuality, the topic of OLED TV lifespan and image retention are unrelated because one does not result in the other. Cases of image retention are affected by viewing patterns, not the age of the TV, so it is inaccurate to connect the two.

Seeing unexpected lines on your phone screen is a common issue for people who dropped their smartphones or have an otherwise damaged screen. The lines can technically run in any direction (vertically or horizontally) but usually you’ll see the damage occur in one direction. In some cases the line will be faint and unnoticeable, but in other cases it can make your phone unclear and difficult to use. And in severe cases your phone can be made completely unusable.

Before I get into any of that, though, there’s one bit of important ‘housekeeping’ to cover: The difference between image retention and screen burn.

There’s always the hope, too, that those pesky TV channels that use the sort of bold logos that can cause image retention and ultimately burn in will eventually start to be more considerate to OLED TV owners by toning down their logos or removing them altogether. In fact, just a week ago the European Broadcast Union issued new guidelines specifically designed to help broadcasters make their logos more organic display friendly.

• Content with black bars either on the top and bottom and/or the left and right sides of the screen. (for example, Letterboxed,4:3 screen, Standard definition)

Image retention is the temporary appearance of a ghostly residue of bold static image elements on the screen. This disappears over time when you’re not watching the same content that caused the retention, or when an OLED TV recycles itself when you power it down. Screen burn is permanent (or extremely long term) image retention that never disappears (or that takes weeks or months to disappear).

It is, however, important that consumers are aware of specific situations that can cause image retention, and the owner’s manual includes recommended measures for preventing this. LG is committed to proactively informing customers so they can enjoy the best image quality and performance from their LG OLED TVs.

The short-term Pixel Refresher automatically starts operating when the user turns off the TV, after viewing for more than four hours in total (in one session or across several). For example, if a user watched TV for two hours yesterday and three hours today (total of five hours), the Pixel Refresher would automatically run for 10 minutes when the TV is next switched off. The user won’t even be aware it’s in operation. If the TV is switched on before the 10-minute operation is complete, the short-term Pixel Refresher will attempt to run the next time the TV is turned off.

After all, when the retention became clear, I hadn’t actually put that many hours onto the TV compared with someone who might be using one as their main living room set. Though at the same time, it’s certainly absolutely true that I’d spent an unusual percentage of my time with the set showing the same footage, counter to LG’s usage advice.

This is actually Rtings’ second stab at measuring how much of a problem screen burn on OLED TVs is, but I kind of dismissed the first one, as its methodology didn’t feel ‘real world’ enough. The latest test, though, seems more sensible in its approach - and suggests that the latest OLED TVs can suffer with screen burn after as little as 4,000-5,000 hours of use.

Maybe the best way to sum everything up is this: while OLED TVs absolutely deserve the love they get for their picture quality potential, for now, at least, we have to accept that OLED TV love comes with a few trials and tribulations in tow.
