The driving backplane comprises: a base substrate (10), a driving circuit, a plurality of electromagnetic structures (13), and a plurality of contact electrodes (12). The plurality of electromagnetic structures (13) in the driving backplane are symmetrically arranged relative to a first straight line (L1) and a second straight line (L2). A current signal can be applied to each electromagnetic structure (13) by means of the driving circuit. Stress generated by a transfer carrier plate (20) according to the magnetic force of each electromagnetic structure (13) moves the transfer carrier plate (20). When the transfer carrier plate (20) is stress balanced in each direction parallel to the surface of the transfer carrier plate (20), the light-emitting diode chip (21) is precisely aligned to corresponding contact electrodes (12).
