摘要： A backplane includes: a substrate including a circuit structure 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 one of the plurality of through holes. 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.

摘要： A display apparatus includes a display module and a camera module. The camera module is within a display area of the display module, and the camera module is over a side of the display module distal to a light-emitting surface of the display module. The display area of the display module includes a light-incident region positionally corresponding to a lens of the camera module, wherein the light-incident region is configured to allow lights from a side of the display apparatus proximal to the light-emitting surface of the display module to pass therethrough to thereby enter the lens of the camera module. The display apparatus further includes a backlight portion over a side of the display module distal to the light-emitting surface of the display module, and the camera module is arranged inside a mounting hole in the backlight portion.
