LG said Samsung’s QD OLED displays are far more susceptible to screen burn

Recently, the competition over OLED panels seems to be escalating, with manufacturers continuously advancing their technology research and development and panel production, creating pressure on Samsung and LG. On the other hand, there is competition and cooperation between Samsung and LG, accompanied by conflicts of interest.

According to TechPowerup, LG recently stated that Samsung’s QD-OLED is more prone to damage than W-OLED. To some extent, this is LG’s retaliation, as Samsung has been criticizing LG’s OLED displays for “burn-in” for some time. LG’s statement is mostly based on Rtings’ tests, which have not been made public yet. However, there is a technical explanation supporting this claim.

QD-OLED uses a traditional RGB pixel arrangement, using the blue element, which has the strongest light energy among red, green, and blue elements, to produce the picture. This feature is the key to the problem, as the aging rate of blue elements is faster, and the aging phenomenon occurs earlier. W-OLED is different because, in addition to the traditional RGB, it also adds white elements, which bear much less pressure per element.

Currently, Samsung is purchasing W-OLED panels from LG for its products, and the two sides have been discussing purchasing prices for quite some time. There has also been a dispute within Samsung over the pricing of QD-OLED panels, rumored to be because W-OLED panels are cheaper than QD-OLED panels, and Samsung Electronics does not want to pay such a high price to Samsung Display to purchase QD-OLED panels, believing that the pricing should be in line with that of W-OLED panels.

LG has not revealed much specific information for now, and perhaps we will have to wait for the next update from Rtings. The new test will be conducted this month.
