Claim 10:
11. A preparing method for a display substrate, comprising:
forming a circuit substrate which comprises an addressing circuit and a plurality of first addressing electrodes;
forming a plurality of elastic electrode pillars on the circuit substrate;
forming a vertical part of a second addressing electrode on each elastic electrode pillar, and forming a horizontal part of the second addressing electrode on a surface of each light-emitting element facing the circuit substrate; and
mounting the light-emitting element on the elastic electrode pillar to allow the horizontal part of the second addressing electrode to be connected to the vertical part of the second addressing electrode, the addressing circuit is configured to provide a first electrostatic voltage to the first addressing electrodes and provide a second electrostatic voltage to the second addressing electrode; the first electrostatic voltage and the second electrostatic voltage are configured to control a deflection angle of the elastic electrode pillar.
