Samsung Electronics pointed out a problem with OLED TVs on its official blog on October 23, mentioning that OLED displays are vulnerable to burn-in and are not suitable for use in TVs.
“A QLED TV got a perfect score in a recent burn-in test conducted by Rtings whereas an OLED TV was rated 5.5 on a scale of 1 to 10,” the company said. It mentioned that this is because a QLED TV is composed of inorganic materials and maintains its color reproduction performance over time whereas that of an OLED TV deteriorates over time as it is made up of organic materials.
“Given that TVs are used without replacement for a long period of time in most cases, OLED TVs are less suitable due to the lack of durability,” it went on to say.
Burn-in is caused by an image shown for a long time at the same position on a TV screen leaving an afterimage even after screen change or affecting the image quality at that position.
Earlier, the company also pointed out OLED displays’ afterimage problems via a YouTube video. The YouTube footage was posted late last month with the title of QLED vs OLED: The 12-Hour Image Retention Test.
