You should know that OLED TVs have their own peculiarities, OLED displays age over time, and the more you watch TV, the faster the process. Unlike conventional LED/LCD displays, OLED TVs create an image by emitting light from each pixel (self-luminous pixels), resulting in perfect blacks and crisp images with no blurring (pixel response time of about 0.1 millisecond).
Due to the nature of the organic materials used to achieve high image resolution, OLED displays are prone to screen lag, which can be a permanent phenomenon. This phenomenon occurs on all OLED panels, and although recommended picture modes can minimize image lag. Unfortunately, current technology cannot completely prevent image lag, or screen burn-in, as it is also called.

Recommendations to protect your OLED TV screen

Displaying the same image for a long period of time or repeatedly displaying the same image can cause image lag, which is a common phenomenon characteristic of OLED panels due to their nature.

Avoid displaying images that may cause image delay and follow these simple guidelines.
Minimize the display of images that could cause
image delay

  • Images with black areas at the top and bottom and/or left and right of the screen.
  • Images that have a 4:3 or 21:9 aspect ratio.
  • Images that remain still for long periods of time, such as a program number, station logo, game console icon, console menu, etc.
  • Other images with a still screen or repeatedly displayed images.

Because this is a common problem, TV manufacturers are developing various features to protect OLED screens. The most common is to automatically turn off the TV when watching a still image for 10 minutes, first the TV automatically reduces the brightness to the minimum, if there is no user response, the TV goes into standby mode. Automatically adjusts the brightness of the picture depending on the ambient light. Also pixels in OLED TVs can accumulate residual glow, to eliminate this problem there are special programs built into the operating system to clean the OLED screen.
