The Article Gives You A Comprehensive Understanding Of OLED Screen Burning Problems
- May 23, 2018 -

Users may have heard that those OLED screens that look great are vulnerable to permanent damage and disrupt the viewing experience. This article will introduce this knowledge.

One of the biggest potential issues for OLED displays such as LG and Sony TVs, Galaxy S9 and iPhone X that can bring a pleasing visual experience to users is burning.

The following CNET will conduct a comprehensive analysis of the OLED screen burn-in phenomenon.

Image Residue PK Burn Screen

First, CNET clarifies two concepts. Although often used interchangeably, "image sticking" and "burning screen" are not the same thing.

· Image sticking is temporary: it will disappear in time.

Burning screen is permanent: it will not disappear.

When the screen disappears, the image is temporarily “sticky” on the display screen and image sticking will occur. For example, the user sees a still photo of a white puppy for 1 hour on the display screen. Then the user decides to watch a movie. For example, watch "Best in Show" on Amazon. However, while watching a movie, the user still sees the white puppy image as if it had a shadow on the screen - staring at your soul.

However, users do not need to be crazy about it. This is just an extreme example of image retention. As the user views a different picture from the white puppy's static image, the residual image of the white puppy may disappear on its own.

Now imagine that the user continuously turns on the TV for a few days or weeks instead of hours and displays the same picture all the time. At this point, the user may really be in trouble. With regard to image sticking, it is usual to look at other contents for a period of time and the afterimage may disappear. For burn screens, afterimages will remain on the display for a long period of time. Maybe it will not stay on the display permanently, but the remaining time is usually more than the user imagines.

This is an extreme situation and the main purpose is to demonstrate what may happen. In fact, the display screen burns much less. Who would like to watch the same television news channel as in the above example for a long time, such as CNN? CNET does not consider whether users can tolerate watching the same TV station for so long, but CNET assumes that users will do so. The same station logo is the image culprit, and even the main culprit of burning screen. The “flying broadcast” area at the bottom of the TV screen is also the main culprit for image retention and even burning.

If the user plays the same video game for hours or even days, the scoreboard or heads-up display area of the game may burn. Basically, images that are displayed on the monitor for a long time and that will not change will cause image retention and eventually burn.
