What is OLED burn in?
First lets talk about what burn-in is in general. When a static element is displayed on-screen for an extended period of time, there is a chance of the residue of the image being retained permanently on the screen. This retention of the ghost of the static image is generically termed as burn-in or screen burn-in. The problem of burn-in dates back to CRT displays like televisons or older computer monitors. This problem however does not exist for modern LED TVs which use an LCD display.
OLED or Organic LED TVs are self emitters. This means that the screen is composed of OLEDs that emit their own light. In LED TV, the LCD screen is illumninated by a panel of LEDs behind it or to the side. Due to this self emissive nature, OLED pixels can retain the ghost of an image if it is displayed for too long and at a high brightness.
Examples of images which can cause OLED burn-in are – TV channel logos, Gaming logos (FIFA etc.), static photos or other logos like Dolby Digital or 4K HDR. In most cases, OLED burn-in is caused only in extreme cases where the TV is being watched with the same static image displayed on part of the screen for a very long (days or weeks). This is usually not the case with an average TV viewer. So unless you are someone who watches the same TV channel for days without switching it off or plays the same video game without turning the TV off, you should not be worried about OLED burn-in. At the same time, it is best to have all the information so you don’t regret making your expensive TV purhase later.
How long does it take for an image to burn-in?
There are no definitive answers to when an OLED TV screen starts to show image burn-in. Some tests have seen burn-in at an overall usage of 4000 hours while some have seen it at lower times. The reality of the matter is that OLED TVs will be susceptible to burn-in purely due to the nature of the technology. As a consumer, you can take some steps in preventing this. If you are watching TV on the same channel with a static logo for a very long duration of time, make sure you watch some other channel before you turn the TV off. Another would be to make sure you do turn your TV off when you are not using it to prevent the TV from displaying the same image while you don’t use.
These tips are applicable only if you use your TV for extended hours on a daily basis. An occasional movie or video game binge is hardly likely to hurt the performance of your TV. Look up your individual TV manufacturers website for more tips on how you can prevent OLED burn-in
What are the solutions for OLED image burn-in?
There are no quick solutions for getting rid of OLED TV burn-in once it sets in. It may take weeks or months for the ghost image to go away completely. In some cases, it might be permanent as well. In the case of burn-in then, prevention as we say is the best cure.
Should I be worried about burn-in when I purchase my next OLED TV?
Currently, Sony and LG – the two big TV manufacturers in the OLED TV space have both noted the burn-in issue on OLED TVs. Each of them have taken several preventative steps on their TVs to prevent burn-in which will be done automatically. Auto-dimming of bright static images, automatic shifting of static images to keep the pixels refreshed are just a couple of such measures.
So, in case you are looking to purchase an OLED TV as your next TV purchase, you should not be worried about burn-in and just enjoy the superlative picture quality that an OLED TV is capable of delivering.
Do OLED TVs have a lower lifespan as compared to LED TVs due to burn-in?
The lifespan of OLED TVs has been a major question mark on them ever since they launched. LG, which is the biggest manufacturer of OLED TVs worldwide says that LG OLED TVs are built to last 100,000 hours. This is well over 15 years even if you watch more than 12 hours of TV per day, every day. Some OLED TVs have a pixel refresh feature that refreshes all pixels. Manufacturers recommend using this feature after every 2,000 hours of usage. Running a pixel refresh can reduce the overall lifespan of your OLED TV but it helps in prevening screen burn-in. Overall, it is safe to say that screen burn-in is not a factor when it comes to the lifespan of OLED TVs.
What do TV manufacturers say about OLED burn-in?
Both Sony and LG, two of the biggest OLED TV manufacturers have acknowledged that due to the nature of the technology itself, screen burn-in is a possibility. Both have also maintained that burn-in will not be caused during the course of regular TV usage. Both have also pro-actively included many automatic measures for preventing screen burn-in.
What can I do to prevent burn-in on my OLED TV?
In the course of regular usage, you should avoid watching any programming on your TV that has a static image for more than 20 hours. To prevent burn-in, can also watch the TV at a brightness setting that feels comfortable without being dim. Higher brightness increases the chances of screen burn-in. If you do notice any signs of burn-in on your TV, you can change the channel to something which does not hvae a static image. Watching this for a couple of hours should help in clearing any burn-in that might have started to set in.
