Abstract
A display backboard includes a base substrate and a plurality of real pixel units periodically arranged on one side of the base substrate. Each real pixel unit has a plurality of real light-emitting layers with different colors, at least two real metal wiring layers are provided on one side of each real light-emitting layer proximal to the base substrate, and two real metal wiring layers on the side of each real light-emitting layer are electrically connected through via holes. Orthographic projections of the two real metal wiring layers on the side of each real light-emitting layer on the base substrate cover an orthographic projection of at least one of the via holes on the base substrate, and the via holes are configured to connect two virtual metal wiring layers in a virtual pixel unit different from the real pixel unit.
