Claim 0:
1. 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 modulate 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 a viewing angle characteristic of the first color light emitted by the first light modulation unit is configured to be substantially the same as viewing angle characteristics of the second color light and the third color light emitted respectively by the second color conversion unit and the third color conversion unit.
