Abstract
A display substrate, a manufacturing method and a driving method thereof, and a display device are provided. The display substrate includes a substrate, a gate layer disposed on the substrate, a gate insulating layer disposed on the gate layer, a pixel defining layer disposed on the gate insulating layer, the pixel defining layer includes a plurality of defining regions, a light emitting layer in the defining regions of the pixel defining layer disposed on the gate insulating layer, wherein the light emitting layer includes an electron excitation layer, a light excitation layer and a hole excitation layer, and a source/drain layer disposed on the light emitting layer. According to an embodiment of the present disclosure, light emission and control of light emission can be realized merely by a three-layer structure of a gate layer, a light emitting layer and a source/drain layer, and compared with the OLED light emitting structure of the prior art, the layer structure is simpler, the light emitted is less blocked, and luminous efficiency is higher.
