QD-OLED

A display technology that combines a blue-emitting OLED layer with red and green quantum dots.

Samsung Display presents QD-OLED as the first display to combine printed quantum dots with self-emitting layers that produce blue light. Red and green quantum dot material is printed on each pixel, converting the blue light into red and green.

In colour-filter displays, colour comes from light passing through a filter, which lowers overall light efficiency. Samsung Display says QD-OLED's narrow spectrum gives high colour purity.

According to the maker, QD-OLED keeps more than 80% of its luminance at 60 degrees off-axis.
