Abstract:
Provided is an organic light emitting diode display. The OLED display includes a thin film transistor substrate, a white OLED layer, a quantum dot photoluminescence film and a color filter film. The OLED display includes sub-pixels, which are sequentially disposed. The sub-pixels include a red sub-pixel, a green sub-pixel and a blue sub-pixel. A region of the quantum dot photoluminescence film corresponding to the red sub-pixel is provided with red quantum dots, and a region corresponding to the green sub-pixel is provided with green quantum dots. The red quantum dots and the green quantum dots are excited by white light emitted by the WOLED layer to emit high-purity red light and green light, respectively, and then filtered by the color filter film to be emitted. Thus, the OLED display has higher color saturation, which effectively broadens color gamut and can fully utilize the short-wavelength light.

Claim (Index 1):
