Precautions for Protecting the OLED TV Screen

Unlike regular LED/LCDs, OLED TVs produce images that emit light for each pixel, achieving a perfect black colour and delivering clear images without blurring.
Due to the nature of the organic materials used to achieve high-resolution image quality, OLED displays generally experience image retention on the screen, which can be a persistent phenomenon. This phenomenon is observed in all OLED panels, and although recommended picture modes can minimise image retention, current technology cannot completely prevent this from occurring.
Displaying the same image for a long time or repeatedly displaying the same image can cause image retention on the screen, which is a common phenomenon in OLED panel products due to the nature of the product. This product has a built-in screen protection feature. Avoid displaying images that are likely to cause image retention, and follow the recommendations.

Images that are likely to cause image retention

  • Images with black areas on the top and bottom and/or the left and right sides of the screen.
  • Images whose aspect ratio is 4:3 or 21:9.
  • Images that are fixed for a long time, such as program number, station logo, game console icon, set-top box menu, etc.
  • Other fixed screen images or repeatedly displayed images.

Running [Pixel Cleaning] to Protect the OLED TV Screen
The OLED TV is equipped with a pixel cleaning feature to check the status of the screen by itself and prevent image retention that leaves an image on a screen. This feature automatically calculates the optimal execution time based on the accumulated viewing time and is automatically executed when the TV is turned off. While this feature is running, horizontal lines may appear at the top and bottom of the screen. The pixel cleaning feature works when the product is connected to the power cord and main power.

Recommendations for Minimising Image Retention
When watching the TV for a long time, press the button on the remote control, go to → [Picture] → [Select Mode] and set the mode to [Eco] / [APS] (Depending on country), go to [Advanced Settings] → [Brightness] and set [OLED Pixel Brightness] to a lower level. In addition, press the button on the remote control, go to → [General] → [OLED Care] → [OLED Panel Care] and set the [Adjust Logo Brightness] value to [High].
When showing images with black bars at the top/bottom/left/right side of the screen, press the button on the remote control, press , and go to [Picture] → [Aspect Ratio] → [User Selection] → [Vertical Zoom] or [4-Way Zoom] to remove the black bars. Turn off the menus for setting up devices such as set-top boxes so that they are not displayed on the screen for a long time.

NOTE: When the screen is showing one fixed image for a long time, the screen brightness will be automatically reduced and then restored once the screen content changes. This is a normal function to minimise image retention.


A television set may fall, causing serious personal injury or death. Many injuries, particularly to children, can be avoided by taking simple precautions such as

  • ALWAYS use cabinets or stands or mounting methods recommended by the manufacturer of the television set.
  • ALWAYS use furniture that can safely support the television set.
  • ALWAYS ensure the television set is not overhanging the edge of the supporting furniture.
  • ALWAYS educate children about the dangers of dimbing on furniture to reach the television set or its controls.
  • ALWAYS route cords and cables connected to your television so they cannot be tripped over, pulled or grabbed.
  • NEVER place a television set in an unstable location.
  • NEVER place the television set on tall furniture (for example, cupboards or bookcases) without anchoring both the furniture and the television set to a suitable support.
  • NEVER place the television set on doth or other materials that may be located between the television set and supporting furniture.
  • NEVER place items that might tempt children to dimb, such as toys and remote controls, on the top of the television or furniture on which the television is placed.

If the existing television set is going to be retained and relocated, the same considerations as above should be applied.
