Claim 6:
7. An organic light-emitting diode display substrate, comprising a light-emitting layer, a light modulation layer, and a color conversion layer, wherein the light-emitting layer is configured to emit a first color light, the light modulation layer and the color conversion layer are arranged on different light-exiting paths of the light-emitting layer, the color conversion layer is configured to convert the first color light into a second color light and a third color light, and the light modulation layer is configured to modulate an emergent direction of the first color light,
wherein the light-emitting layer comprises a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit that are periodically arranged on a driving substrate and emit the first color light, the light modulation layer comprises a first light modulation unit and a second light modulation unit that are arranged on a light-exiting path of the first light-emitting unit and modulates the emergent direction of the first color light, and the color conversion layer comprises a second color conversion unit that is arranged on a light-exiting path of the second light-emitting unit and converts the first color light into the second color light and a third color conversion unit that is arranged on a light-exiting path of the third light-emitting unit and converts the first color light into the third color light, and
wherein difference between an attenuation of brightness of blue light (Xb) and an attenuation of brightness of white light (Xw) is less than 12% at a viewing angle of 30°, wherein the attenuation of brightness of blue light at a viewing angle of 30° is calculated as Xb in percentage based on the blue light brightness at the viewing angle of 0° assumed as 100%; and the attenuation of brightness of the white light at a viewing angle of 30° is calculated as Xw in percentage based on the white light brightness at the viewing angle of 0° assumed as 100%.
