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.

Abstract: The present invention provides a display panel and a method of manufacturing the same. The display panel employs a target light transmission layer disposed on a target light conversion layer for transmitting the target light generated by the target light conversion layer and reflecting the excitation light passing through the target light conversion layer, such that the target light emitted by the sub-pixel units is mixed with a small amount of excitation light or even without excitation light, so that the target light emitted by the sub-pixel units is relatively pure, thereby solving the technical problem that the existing micro-display technology has defects.

Abstract: A liquid crystal display panel and a liquid crystal display device are provided. The liquid crystal display panel includes a color film substrate, an array substrate disposed opposite to the color filter substrate, and a liquid crystal layer disposed between the color filter substrate and the array substrate. The color film substrate includes color filter layers arranged into an upper and a lower layer, positions of the upper and lower layers corresponding one-to-one, and colors thereof corresponding with a same color. A fingerprint recognition unit is disposed between the color film substrate and the array substrate. When fingerprint recognition is performed, the upper layer blocks large-angle reflection light of fingerprints and improve a “signal-to-noise ratio” of reflection light of the fingerprints emitted to the fingerprint recognition unit, thereby improving accuracy of the fingerprint recognition. The liquid crystal display device of the invention includes the above liquid crystal display panel.
