Method for preparing display substrate and display substrate

A method for preparing a display substrate, comprising:

• providing a driving substrate;
• wherein the driving substrate comprises:
• a base substrate;
• a pixel driving circuit layer, arranged on the base substrate;
• a first pad and a second pad, spaced from each other, arranged on a side of the pixel driving circuit layer away from the base substrate, and connected to the pixel driving circuit layer;
• and
• an electrostatic protection alignment, spaced from the first pad;
• wherein the first pad comprises a first toothed tip arranged on a side of the first pad facing the electrostatic protection alignment, and the electrostatic protection alignment comprises a second toothed tip arranged on a side of the electrostatic protection alignment facing the first pad;
• and
• transferring a light-emitting element to the driving substrate, such that an anode of the light-emitting element is connected in alignment with the first pad and a cathode of the light emitting-element is connected in alignment with the second pad;
• wherein the providing a driving substrate comprises:
• providing the base substrate;
• preparing the pixel driving circuit layer on a side of the base substrate;
• wherein the pixel driving circuit layer comprises a plurality of pixel regions on a surface of the pixel driving circuit layer, the plurality of pixel regions being arranged in an array;
• and
• preparing the first pad, the second pad, and the electrostatic protection alignment on the side of the pixel driving circuit layer away from the base substrate;
• wherein the first pad and the second pad are formed in each pixel region, and the electrostatic protection alignment is spaced from the second pad;
• the second pad comprises a third toothed tip arranged on a side of the second pad facing the electrostatic protection alignment, and the electrostatic protection alignment comprises a fourth toothed tip on a side of the electrostatic protection alignment facing the second pad.
