  • Publication number: 20240145492
    Abstract: A light-emitting substrate and a manufacturing method thereof are provided. The reactivity of part of the ink layer outside the preset area that is far from the light with the first preset wavelength is improved by a heating process. Thus, the part of the ink layer reacts sufficiently under irradiation of the light with the first preset wavelength at lower energy. This improves an undercut issue caused by insufficient curing of the ink layer outside the preset area far from the light with the first preset wavelength, thereby preventing the ink layer from being peeled off from the light-emitting substrate.

  • Publication number: 20240063351
    Abstract: A display panel, a method of manufacturing the same, and a spliced display screen are disclosed. A driving substrate includes a plurality of first signal wirings and a plurality of light-emitting devices arranged in an array on the driving substrate. Each of the light-emitting devices is electrically connected to a corresponding one of the first signal wirings on the driving substrate. A protective layer covers the light-emitting devices and the driving substrate. One end of each of the first signal wirings is exposed at the protective layer to form an exposed end. The cladding layer covers the exposed end of the first signal wiring, so that the first signal wiring can be prevented from being exposed to cause line corrosion, thus alleviating a problem of line corrosion caused by exposed metal wirings in current display panels.

  • Patent number: 11815760
    Abstract: A display panel and a display device are provided. The display panel includes an array substrate, an optical function layer, and an anti-reflection layer. The optical function layer and the anti-reflection layer are located on the array substrate, material of the anti-reflection layer includes a sulfur-containing material, and a refractive index of the anti-reflection layer is between refractive indexes of two film layers adjacent to the anti-reflection layer. Since the refractive index of the anti-reflection layer is between the refractive indexes of the two film layers adjacent to the anti-reflection layer, reflection of external light on the display panel is reduced, thereby improving a display effect of the display panel.

  • Publication number: 20220308387
    Abstract: The present disclosure provides a black matrix for LCD panel and the LCD panel. The black matrix is a pattern layer of MoTi, and a thickness of the pattern layer of MoTi ranges from 1000 ? to 2000 ?. MoTi is used as the black matrix material instead of resin-type black matrix. MoTi has desirable light-shading performance, and the thickness of only 0.1 ?m thereof can achieve the same effect as the existing resin-type black matrix with a thickness of 1 ?m, which effectively reduces the thickness of the black matrix, flattens the substrate topography, and benefits to the flow of the alignment liquid to effectively improve the non-stick defect of the alignment liquid, so that the thickness of the alignment film is uniform and the quality of the liquid crystal display panel is improved.

  • Patent number: 10821467
    Abstract: An alignment film coating machine and a coating method are provided. The alignment film coating machine includes an equipment for carrying a substrate, a spray head for spraying PI droplets, and an air knife disposed on the equipment and located on one side of the spray head. The air knife is used for moving along the equipment and blowing uniform impact air curtain to the PI droplets after the spray head sprays the PI droplets on the substrate. By adding the air knife into the alignment film coating machine, the diffusion ability of the PI droplets is improved due to the uniform impact air curtain blown by the air knife. The resistance in diffusion is overcome. The PI droplets enter the via hole. Mura, which is induced by a relatively thicker PI film around the via hole as a result of the accumulation of the PI droplets, is prevented.
