The South Korean manufacturer Samsung plans to start production of QD OLED panels for PC monitors later this year. The result will be displays in 34-inch format, according to Joo-Sun Choi, head of Samsung’s display division. “Heise.de ” operated. Production will start in parallel with the 55- and 65-inch QD OLED panels for smart TVs. The first models are expected to go on sale next year.
With QD-OLED, the name says it all, because the new screen technology is a combination of quantum dot displays (QD) and OLED panels. Since the two technologies have different strengths and weaknesses, their combination could achieve what “Whathifi.com titled “holy Trinity of TV production”: vivid colors, high peak brightness without bleeding out and dark, rich blacks. You can read how the two combined technologies work in the article “The subtle difference between LCD, LED, OLED and Co.”.
Subpixels produce real white light
How “Whathifi.com ” according to reports, QD-OLEDs uses layered, blue OLED material to illuminate pixels containing red and green quantum dots. Each OLED pixel is divided into three subpixels: one blue, one red and one green. These can then be combined to create real white light. Practically no light energy is lost in the color transformations performed by the quantum dots. With this method of OLED lighting, the new QD OLEDs should appear brighter than current OLED TVs and at the same time be able to be completely dimmed.
According to the online portal, Samsung’s QD OLED displays will have 4k resolution and will have about 8.3 million light sources that can be controlled separately. Thus, a contrast ratio of 1’000’000: 1 is possible. In addition, the new displays should deliver 0.0005 nits black and 1000 nits top white.
Since the new panels do not require an LCD display, they should offer a faster response time and a larger viewing angle than LCD displays. The screen reflection should also be lower. Samsung also states that the screens reduce harmful blue light by 40-50 percent, since the blue OLED material mainly produces light with a wavelength of more than 455 nanometers.
