Light emitting display apparatus and substrate providing uniform brightness of different positions of setup region

A display substrate, comprising a setup region having an acquisition region for an image acquisition unit arranged at a side of the display substrate away from a display side and a transition region adjacent to the acquisition region, wherein the display substrate comprises:

• a base substrate;
• a plurality of light emitting devices on the base substrate, wherein at least a part of the plurality of light emitting devices are provided at each of the acquisition region and the transition region;
• and
• a plurality of driving circuits on the base substrate, each of which comprises a driving transistor and is configured to provide a driving signal to a corresponding light emitting device;
• wherein
• driving circuits of the plurality of driving circuits corresponding to light emitting devices in the transition region are referred to as first local driving circuits which are located in the transition region;
• driving circuits of the plurality of driving circuits corresponding to light emitting devices in the acquisition region are referred to as peripheral driving circuits which are located in the transition region and are connected to the light emitting devices through connection lines, respectively;
• and
• at least a part of the connection lines each comprise:
• a connection portion between a corresponding light emitting device and a corresponding peripheral driving circuit, and an extension portion connected to the connection portion, and the connection lines are uniformly distributed in the setup region;
• and
• wherein the transition region comprises at least one sub-transition region outside the acquisition region on at least one side of the acquisition region in a first direction;
• and
• the connection line connected to the peripheral driving circuit in each of the at least one sub-transition region extends into the acquisition region at least from a position in the sub-transition region farthest from the acquisition region.
