The light emitting unit includes a light emitting diode (LED) chip including a light emitting surface, and an optical functional film disposed on the light emitting surface of the LED chip, where a light transmittance of the optical functional film is greater than 95% in a wavelength range of 350 nm to 480 nm.

Abstract: The present invention provides a color conversion layer, a manufacturing method of the color conversion layer, and a display panel. The color conversion layer is used in a display panel having a direct surface light source. The color conversion layer includes a quantum dot film and a functional film. The functional film is arranged at one side of the quantum dot film facing the direct surface light source. A light wave emitted by the direct surface light source is transmitted through the functional film into the quantum dot film. A light wave excited by the quantum dot film is reflected into the quantum dot film through the functional film.

Abstract: The present disclosure discloses a backlight module and a display device. The light emission direction of at least one of the lamp source and the fluorescent film is provided with a diffusely reflecting layer. The diffusely reflecting layer arranged above the lamp source diffusely reflects pump light emitted from the lamp source, which may enhance uniformity of the pump light. The diffusely reflecting layer arranged above the fluorescent film scatters light emitted from the fluorescent film, scatters the light and distributes the light to a larger range, which may improve light mixing uniformity and improve the uniformity of light emission brightness.

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.

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: 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.
