Claim 18:
19. A preparation method for a display substrate, comprising:
providing a substrate;
forming, on the substrate, M rows of scanning signal lines and M rows of light-emitting signal lines and a drive structure layer in a display region; wherein the drive structure layer comprises: a pixel circuit array and a driving circuit array that extend in a column direction; the pixel circuit array and the drive circuit array are arranged in a row direction; the pixel circuit array comprises: M rows and N columns of pixel circuits, an ith row of pixel circuits are electrically connected to an ith row of scanning signal line and an ith row of light-emitting signal line, where 1≤i≤M; the drive circuit array comprises: at least one scanning drive circuit and at least one light-emitting drive circuit, the scanning drive circuit is arranged to provide a drive signal to a scanning signal line, and the light-emitting drive circuit is arranged to provide a drive signal to a light-emitting signal line; and
forming a light-emitting structure layer on the drive structure layer; wherein the light-emitting structure layer comprises: M rows and N columns of light-emitting structures, the pixel circuits are in one-to-one correspondence with the light-emitting structures and are electrically connected to corresponding light-emitting structures.
