The terms OLED and QLED regarding display technologies are likely familiar to you by now. Now you can memorize another new abbreviation, namely QD-OLED. This technology from Samsung promises change! Under the name QD display, Samsung Display developed new flat screens in which quantum dots (i.e. semiconductor crystals) generate colored light in individual pixels. Hence the name QD-OLED. This is an absolute novelty, i.e. a new type of OLED display.
How does the new technology differ from QLED and OLED?
On OLED models, on the other hand, we’ve had to do without Quantum Dot technology up until now. Samsung Display is now changing that with the new devices, and the question naturally arises whether the new screens are better than previous OLEDs thanks to QD. Until now, OLED displays for TVs were designed to light up independently and work without a backlight. The structure of QD OLEDs is quite similar to that of its predecessors, except that the quantum dots in each individual pixel generate colored light. This is very deep red and green, while the blue tone comes from an OLED light source. The red and green pixels of the QDs absorb the blue light and convert it into their own color. Or to put it another way: The panels of the QD OLEDs emit blue light, which in turn is converted into red and green by a QD filter – you can see this on the graphic accompanying the article.
So the picture quality advantages of Quantum Dot OLED technology are multi-layered. On the one hand, we are looking forward to real black levels without blooming effect and absolute peak brightness at the same time. Presumably, a wide viewing angle and of course a huge HDR color space with rich colors go hand in hand with that. However, protective measures against afterimages (so-called burn-in) might be necessary. This is already known from current OLED TVs.
It will still be a while before we can expect the first QD OLED TVs. Until then, however, it is of course very exciting for us to adjust to the new screen technology. According to the current status, it will be models in the sizes 55 and 65 inches. We remain curious and will, of course, inform you when there is news.
