OLED Burn-In


What is OLED burn-in?


OLED TVs use organic LEDs to display an image. Each pixel in the image is an organic LED that emits light. While this technology has many advantages and produces fantastic images, it has one major drawback: Organic LEDs age relatively quickly, which means that their luminosity diminishes over time. The longer and brighter the LEDs shine the faster they age.

If constantly changing content is displayed on the TV, all LEDs age equally quickly. This would only mean that the OLED TV generally loses brightness over time. However, if static content is played on the TV, with some areas in the picture being brighter than others, then those LEDs in the bright areas will age faster. These LEDs no longer shine as brightly as the others, even if different content is being displayed. As a result, there are dark spots on the TV that are always visible. This is called OLED burn-in.

How can I avoid burn-in on my OLED TV?


Simply put, don’t play the same static video on an OLED TV 24/7 for weeks as it would lead to burn-in.

However, if you play a 2 hour long static video every now and then or even once a day, then you shouldn’t worry about burn-in. Playing different static videos around the clock is also no problem as long as they don’t all have the same logo. Otherwise, after a while, only the logo would be burned in.

The guys from rtings.com tested a LG B6 OLED TV for burn-in, and the results can be seen here:

They played a video loop with a static bright logo in the upper left corner for 20 hours a day, 7 days a week. Only in the 5th week did the first slight burn-in from the logo become visible.

Why don’t other TVs have burn-in?


Most of the other TVs on the market use LCD technology. With this technology, there is no aging of the individual pixels. Therefore there is no burn-in.
