OLED with the brilliance of church windows
At the CES, Sony is presenting the premium televisions in its “MASTER series” with new screen technology.
The displays referred to as “quantum dot OLED” (QD-OLED for short) essentially consist of a blue OLED panel with layers of red and green nanocrystals, the so-called quantum dots, superimposed on top of it. The blue light of the OLEDs stimulates the quantum dots to shine, which in turn emit intense red and green light. An effect which, by the way, was already used in medieval church windows and which is already proven technology in LCDs. As a result, QD OLEDs should clearly surpass conventional OLEDs in terms of color intensity and brightness.
Since, according to Sony, the displays do not require additional color filter layers, they scatter the light evenly on all sides. In contrast to liquid crystal screens with quantum dots, there is no weakening of color and contrast when viewed from the side. A heat-conducting layer on the back counteracts the so-called “burn-in effect”.
Sony is silent about the manufacturer of the QD OLED panels. But they probably come from Samsung Displays’ factories. Since last autumn at the latest, reports have been circulating that quantum dot displays have been made ready for the market there. It is noteworthy, however, that Samsung has not yet introduced any televisions with this new display technology.
Sony will use the QD OLEDs in its 4K premium models Sony XR-55A95K (55 inches) and Sony XR-65A95K (65 inches). Information on prices and the European market launch will only be announced later.
