Samsung’s new TV rumored to be its first with OLED panel from rival LG Display

QD-OLED screens differ from the traditional OLED panels that’ve long been manufactured by LG Display in the way they produce an image. LG’s displays are considered WRGB OLED because they use blue and yellow OLED compound to generate white-ish light pixels that are passed through color filters to produce red, green, and blue sub-pixels. More recent OLED TVs also have a fourth unfiltered / white sub-pixel meant to enhance brightness — especially for HDR content.

QD-OLED changes this up by emitting blue light through quantum dots to convert some of that blue into red and green without any need for the color filter. (Blue is used because it has the strongest light energy.) This leads to greater light energy efficiency; since you’re not losing any light to the color filters, QD-OLED TVs should offer brightness gains compared to past-generation OLEDs.

They should also be able to maintain vivid quantum dot color reproduction even at peak brightness levels, whereas WRGB OLED can sometimes exhibit some desaturation when pushed that far. In Sony’s case, the company is claiming that QD-OLED “boosts color brightness by up to 200 percent compared to conventional TVs.” The already superb viewing angles of OLED are claimed to be even better on QD-OLED since there’s more diffusion happening without the color filter in the way.

The possibility of burn-in isn’t eliminated by QD-OLED, but the hope is that these panels could exhibit a longer overall life span than existing OLED TVs since the pixels aren’t working as hard. Samsung Display is using three layers of blue OLED material for each pixel, and that could preserve their longevity.
