At a press conference, LG Display accuses its competitor Samsung that their new QD OLED panels are more prone to burn-in than LG’s own WOLED displays. The company relies on test results from Rtings. The white subpixels on WOLED panels are supposed to make the difference, while Samsung only uses RGB subpixels on QD-OLED.
The question of which technology is the gentlest for televisions has now become an issue again in LG’s display division, because the South Koreans took a dig at their domestic competitor Samsung at a recent press conference, as Forbes reports. In the past, Samsung is said to have encouraged people to buy its LCD TVs, arguing that LG’s OLED models are prone to burn-in. Last year, however, Samsung introduced its own OLED technology.
Samsung’s QD OLED TVs more prone to burn-in, according to LG Display
The moment of counterattack seems to have come for LG Display. Citing Forbes, LG threw back the accusation of burn-in on its OLED displays at a press conference earlier this week – at which the “third generation” of OLED panels with MLA technology was one of the topics. Measurements of a test series of televisions are decisive for this Website Rtings in November 2022 had determined.
LG Display is said to have shown screenshots of its own OLED TVs from 2022, G2 and C2. This was contrasted with images from two TVs using Samsung’s QD-OELD technology. One is the S95B from Samsung and the other is the A95K from Sony. The latter are said to have shown clear signs of burn-in on their screens. However, LG Display didn’t just leave it at the “proof photos” from Rtings, but also provided a technical explanation afterwards.
As Forbes writes, LG uses WOLED technology, which is said to be less prone to burn-in than Samsung’s QD-OLED technology. The main reason for this are the white sub-pixels in WOLED, which contribute to the generation of static images and are intended to ensure better brightness on larger screens. Interestingly, Samsung is said to have criticized the competitor for years because it means that no pure RGB image can be delivered. Samsung, on the other hand, achieves the necessary brightness with its QD-OLED technology via a blue OLED layer behind a quantum dot layer. In terms of brightness, QD-OLED should even surpass LG displays WOLED. Thanks to the white subpixels, however, according to LG Display, the RGB subpixels are less stressed when generating static images.

Thus, the solution with pure RGB subpixels is more susceptible to burn-in than with additional white subpixels. It remains to be seen whether and when Samsung will react to this return carriage. According to Forbes, however, the manufacturer could point to improved thermal management and a new OLED “HyperEfficient Electroluminescence” material in its second generation of QD OLED televisions, which should reduce the susceptibility to burn-in as a result.
