Abstract: A display panel, a manufacturing method thereof, and a display device are provided. The display panel includes a driving backplate, functional component groups, and micro-LED chips. The functional component groups are integrated in regions where the micro-LED chips are not disposed and are multiplexed as alignment marks. In a mass transfer process of the micro-LED chips, the alignment marks are prevented from additionally occupying pixel space by using part of functional components multiplexed as the alignment marks under a precondition of ensuring alignment accuracy.

Abstract: A backlight module and a liquid crystal display are provided. The backlight module has a substrate, a plurality of soldering pads, and a reflective pattern layer. The soldering pads are distributed on the substrate and each of the soldering pads has a soldering pad size. The reflective pattern layer covers the soldering pads and the substrate. The reflective pattern layer has openings, positions of the openings correspond to positions of the soldering pads, each of the openings has an opening size, and the opening size is smaller than the corresponding soldering pad size. The backlight module is provided with the openings in the reflective pattern corresponding to the positions of the soldering pads, and the opening size of the openings is smaller than the soldering pad size of the soldering pads, thereby increasing a ratio of the reflective pattern layer to the substrate. Therefore, brightness is improved.

Abstract: A naked-eye stereoscopic display grating, manufacturing method and display device are disclosed. The method includes: preparing a transparent substrate; depositing a metal oxide layer on the transparent substrate; depositing a metal grating layer on the metal oxide layer, wherein, a reflectivity of the metal oxide layer is less than a reflectivity of the metal grating layer; and adopting a photolithography method to etch the metal oxide layer and the metal grating layer in order to expose a portion of the transparent substrate to form a transparent region and a reflective region arranged periodically. Accordingly, the present invention can increase the usage efficiency of the light, decrease a color crosstalk problem and low contrast ratio problem caused by an environment light reflected by the metal grating layer and the light in the panel.
