Claim 10:
11. A method for preparing a display substrate, the display substrate comprising a display area, a peripheral area and a binding area, the peripheral area being located at a periphery of the display area and the binding area being located on one side of the peripheral area away from the display area; the method comprising:
forming an array structure layer on a silicon-based substrate; a driving transistor and a first power line being arranged in the silicon-based substrate in the display area, and a first electrode of the driving transistor being connected with the first power line; a power supply electrode and a second power line being arranged in the silicon-based substrate in the peripheral area, and the power supply electrode being connected with the second power line; and a bonding pad assembly being arranged in the silicon-based substrate in the binding area, and the bonding pad assembly being connected with the first power line and the second power line; and
forming a light emitting element and a binding platform on the array structure layer; the light emitting element being located in the display area, and an anode of the light emitting element being connected with a second electrode of the driving transistor; the binding platform being located in the binding area, and the binding platform being connected with the bonding pad assembly by a conductive pillar; and the binding platform and the anode of the light emitting element being arranged on the same layer, and the binding platform being configured to be bound to a flexible printed circuit.
