Definition: QD-OLED

An OLED display technology that uses quantum dots as the color creators. When the blue backlight hits the red and green quantum dot subpixels, red and green are generated. Because blue is the backlight, it serves as the blue subpixel. See quantum dot.

In a QD-OLED screen, the number of layers is significantly less than in an OLED screen. For details about the OLED technology, see OLED layers and OLED.

Keeping It Straight: QD-OLED and QLED
QD-OLED is an OLED technology that uses quantum dots, whereas QLED is an LCD screen that uses quantum dots to enhance the backlight (see QLED).

Quantum Dots Replace Color Filters

The red, green and blue colors in a QD-OLED screen are generated from red and green quantum dots and a blue backlight. In contrast, a regular OLED screen uses a color filter layer (CF). See quantum dot.
