What is QD-OLED? Samsung QD-OLED TV


At CES 2022, Samsung unveiled its latest QD-OLED TV, taking home the Best of Innovations 2022 award with the world's first true RGB self-emitting quantum dot OLED display. You may already be familiar with QLED and OLED, but what is QD-OLED? This article will introduce you to its advantages.​

QD-OLED as the name implies is the use of Quantum Dot (QD) and OLED technology, the structure of the blue OLED light-emitting panel as the "backlight", while the red and green is similar to QLED TV, the light source to excite the way the quantum dots emitted. Each OLED pixel on a QD-OLED is divided into 3 sub-pixels, the blue sub-pixel native to the blue OLED, and the red and green sub-pixels generated by the excitation of different quantum dots by the blue OLED, which can be combined to form white light.​


Since the process of excitation of color light by quantum dots is very efficient and there is almost no loss of light energy, it is possible to obtain a stronger brightness than the current OLED.​

The structure of a QD-OLED panel consists mainly of a blue OLED backlight (individual OLED pixels) plus a quantum dot light-emitting layer that excites both red and green colors.​

QD-OLEDs also have the benefits of QLEDs, with rich, pure colors inspired by quantum dots that can cover up to 80% of the BT.2020 color gamut.

QD-OLED panel brightness range from 0.0005 - 1,000nits, although the maximum brightness is still not as high as QLED, but the contrast is higher, can present a more complete HDR effect​
