Assignee: BOE TECHNOLOGY GROUP CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A display substrate comprising:
a base substrate;
a sub-pixel, provided on the base substrate and comprising a pixel circuit, wherein the pixel circuit comprises: a driving circuit, a data writing circuit, a first light emission control circuit, a first light emission control line and a light emitter element,
the driving circuit comprises a control terminal, a first terminal and a second terminal, and the driving circuit is configured to control a driving current, which passes through the first terminal and the second terminal, for driving the light emitter element to emit light;
the data writing circuit is configured to write a data signal to the driving circuit in response to a scan signal;
the first light emission control circuit is configured to apply a first voltage to the first terminal of the driving circuit in response to a first light emission control signal provided by the first light emission control line in an initialization stage; and
the first light emission control line extends along a first direction, and a second direction intersects with the first direction; in the second direction, an orthographic projection of the first light emission control circuit on the base substrate is at a side of an orthographic projection of the driving circuit on the base substrate away from an orthographic projection of the data writing circuit on the base substrate;
the display substrate further comprises:
a second light emission control circuit, configured to apply the driving current to the light emitter element in response to a second light emission control signal; and
a second light emission control line, configured to provide the second light emission control signal, wherein
the first light emission control line and the second light emission control line extend along a same direction;
the first light emission control line and the second light emission control line are two different lines arranged in the second direction and do not overlap with each other in a direction perpendicular to the base substrate.
