Abstract
A backplane includes: a substrate including a circuit structure layer and a second reflective layer, a first reflective layer disposed on a bearing surface of the substrate, a plurality of light-emitting diode chips, and a plurality of optical structures. The first reflective layer includes a plurality of through holes spaced apart. A light-emitting diode chip in the plurality of light-emitting diode chips is located in a through hole. The plurality of light-emitting diode chips are electrically connected to the circuit structure layer. The circuit structure layer is configured to drive the plurality of light-emitting diode chips to emit light. An optical structure in the plurality of optical structures covers the light-emitting diode chip, a light incident surface of the optical structure is in contact with a light exit surface of the light-emitting diode chip, and a light exit surface of the optical structure is a curved surface.
