There has long been talk of QD-OLED panels that combine the benefits of OLED and quantum dots. At this year’s CES, they were first seen at Samsung Display. However, Sony will sell them, Samsung prefers to squeeze the QLED to the maximum.
Samsung TVs are manufactured by Samsung Electronics, which has preferred LCD panels enhanced by quantum dots for many years. It uses the marketing name QLED for them. On the contrary, it has been rejecting OLED technology for a long time. OLED panels for televisions are manufactured exclusively by LG and supplied to other brands. Samsung Display is in charge of the panels at Samsung Display, and although it is one conglomerate with Samsung Electronics, they obviously did not agree on a cooperation.
The QD-OLED panel from CESU is not yet a finished TV, Samsung presented it without a Smart TV or tuner. But fitting into a TV chassis is the easiest. Surprisingly, the first TVs with a QD-OLED panel will not be those from Samsung.
There may be several reasons, but most likely Samsung Electronics does not want to cannibalize its current cutting-edge technologies, and Samsung Display would not be able to supply them with enough panels anyway. It is still very difficult to produce a QD-OLED and the price of the panel will be relatively high. It may be different in a year.
Samsung Display has thus agreed with Sony, which produces orders of magnitude fewer TVs (Samsung is the largest manufacturer in the world). In addition, Sony likes to experiment with new and expensive technologies.
QLED vs. YOU ARE
QLED is a classic LCD panel supplemented with a layer of quantum dots. These are nanoparticles of crystalline material capable of absorbing and emitting photons. They have different sizes (2 to 10 nm), which determines the radiated wavelength and thus the color of the light. For physical reasons, a blue light is used, which changes to green or red as required. The same principle works, for example, with LG LCD panels marked as NanoCell.

OLED is another type of panel and consists of electroluminescent diodes using organic material (hydrocarbons). It uses WRGB subpixels including white (which is mainly used to increase the maximum brightness) and each pixel lights up on its own. No backlight is required. This means virtually perfect contrast, which the LCD tries to catch up with more backlight zones (such as MiniLED technology). OLED will have lower brightness or color saturation than QLED, but much better latency.
Sony will try it first
Probably a top-notch TV that overshadows everyone else for a while (even with the price), it will Sony Bravia A95K Master Series with QD-OLED panel. There will be more OLED models in Sony’s top line of TVs this year, but only the highest will have no OLEDs from LG, but QD-OLEDs from Samsung. Sony refers to this TV as an OLED and only in parentheses inconspicuous states that it is a QD-OLED. Sell it will be in sizes 55 and 65 ″ and in both cases it will be 4K.

The camera is intended for multiple purposes. For example, it recognizes when no one is watching TV and dims the brightness

Sony will further enhance its top-of-the-line TVs with its own Cognitive Processor XR image system, and of course support for HDR or HDMI 2.1 ports. However, MediaTek is likely to remain slower for Smart TV. Sony also stays with its own Acoustic Surface technology, where the sound from the speakers passes through the screen.
It will be interesting to see how many panels Samsung manages to produce (probably relatively few) and how many of these expensive Sony TVs will sell (there will not be many either). And maybe it will be even more interesting when Samsung Electronics itself starts selling QD-OLED TVs, which has to prepare the marketing ground for them. For example, they might have a completely different name, with the emphasis on the word “quantum” and the backward word “OLED”.
LG will also improve the OLEDs for this year, it has nothing else to do. The novelty is called OLED EX and uses deuterium in diodes instead of hydrogen. This is to ensure a third higher brightness.
QD-OLED in monitors
QD-OLED also appears in the world of computer monitors. At CES, he was shown by Alienware in the body of a 34 řiv curved game monitor as the AW3423DW. It will have a resolution of 3440 × 1440 px and a refresh rate of 175 Hz via DisplayPort (or 100 Hz via HDMI).

Samsung has shown a combination of OLED and QLED panels. But you will buy QD-OLED TVs of the future from Sony first
