Display Substrate and Display Apparatus

A display substrate, comprising:

• a display region and a non-display region,
• the display region is provided with M1 rows and N1 columns of pixel circuits and M2 rows and N2 columns of light emitting units, each light emitting unit comprises:
• a first light emitting device, a second light emitting device, and a third light emitting device, wherein the first light emitting device, the second light emitting device, and the third light emitting device emit light of different colors;
• wherein M1≠M2, N1≠N2;
• each pixel circuit is connected with K light emitting devices emitting light of a same color, wherein K is a positive integer greater than or equal to 2;
• each pixel circuit comprises a current control sub-circuit and a light emitting selection sub-circuit;
• the current control sub-circuit is respectively connected with a reset signal terminal, an initial signal terminal, a scan signal terminal, a data signal terminal, a light emitting control terminal, a first power supply terminal, and a first node, and is configured to provide a drive current to the first node under control of the reset signal terminal, the initial signal terminal, the scan signal terminal, the data signal terminal, the light emitting control terminal, and the first power supply terminal;
• the light emitting selection sub-circuit is respectively connected with the first node, K light emitting selection signal terminals, and the K light emitting devices emitting light of the same color, and is configured to sequentially provide a signal of the first node to the K light emitting devices emitting light of the same color under control of the K light emitting selection signal terminals.
