QD-OLED (Quantum Dot Oraganic Light Emitting Diode)

Quantum Dot meets OLED

QD-OLEDs use a screen that works on the basis of blue light spectrum. This is ensured by a respective layer inside the panel in combination with tiny crystals. These so-called quantum dots are attached to the surface and convert the incoming light waves into red and green only in a second step.

This way – in contrast to the existing approach with red, green and blue light-emitting diodes – a better contrast ratio is achieved in addition to a wider color space and higher color accuracy. This allows QD models to make a leap forward in terms of brightness performance as well. 

Interest in QD-OLEDs still low

The concept was first introduced in 2021 by Samsung Display, a subsidiary of Samsung Electronics that specialises in display manufacturing. The first TV based on this approach is the Samsung S95B QD-OLED, launched in 2022. 

Although the technology has not yet found widespread acceptance on the market, Samsung is continuing the development of the idea in 2023 and has added two additional models based on this standard to its QD range: the S90C and S95C.
