Abstract

The present invention provides a backlight assembly defined with a camera area. The backlight assembly comprises a substrate layer on which a reflective layer is disposed, and an optical layer is disposed on the reflective layer. The optical layer is provided with a through hole in the camera area, and an annular light-guide film circles a peripheral of the through hole, wherein an inner ring of the light-guide film is concentrically arranged with the through hole. The invention provides a backlight assembly, which introduces an annular light-guide film to control the direction of light propagation in a certain area around the under-screen camera, so that the light is evenly distributed over the camera area, and the camera area can still perform display function by a liquid crystal layer of the screen corresponding to the camera area, thereby providing a new type of under-screen camera solution.
