Sony first out of the gate with QD-OLED display tech
Sony has introduced the first QD-OLED TV at CES 2022 in Las Vegas. The company’s current OLED sets use panels from LG tuned with Sony’s processing.

The technology is a combination of the Quantum Dot (QD) displays, endorsed by Samsung, and OLED technology, of which LG is the dominant player.

This description from What HiFi describes the technology behind it; A QLED uses an LED backlight, a layer of quantum dots, an LCD matrix, and a colour filter to create an image. The quantum dots in QLEDs are tiny semiconductor particles only a few nanometers in size. The dots convert white light into coloured light without loss of energy. The resulting colour depends on the size of the quantum dot itself – larger ones give off light at the red end of the spectrum, smaller ones at the blue end. The advantage of quantum dots is that they offer significantly improved colours over both traditional LCD and, arguably, even over OLED. At the same time, the backlight and energy efficiency of the dots creates brightness levels that OLED can’t get close to. However, it still can't achieve the deep blacks of an OLED as light can bleed from white areas to bordering dark pixels.

The flagship Bravia XR A95K TV will include a QD-OLED (quantum dot organic light emitting diode) panel manufactured by Samsung, and will come in 65-in and 55-in sizes, both with 4K resolution.
