Abstract: An alignment coating method for a substrate includes providing at least one substrate and at least one alignment plate, covering the alignment plate on to the substrate, coating polyimide liquid on the alignment plate, and transferring a polyimide liquid on the alignment plate to a region out of a blind via on the substrate according to a preset printing direction through a printing mechanism. Each of the substrates has the blind via. The alignment plate has at least one opening. The opening corresponds to the blind via.

Abstract: A display panel, which includes a display area, a transition area, and a blind hole area. The transition area is provided with a plurality of pixel units, and each of the plurality of pixel units comprises a blue sub-pixel, a red sub-pixel, and a green sub-pixel; wherein in the transition area, an aperture ratio of each of the red sub-pixels and an aperture ratio of each of the green sub-pixels are both less than an aperture ratio of each of the blue sub-pixels.

Abstract: The present invention provides a color filter substrate, a display panel, and an electronic device. The color filter substrate includes a preset region, a display region, and a light-shielding region. The light-shielding region is provided with spacers. The light-shielding region includes a first sub-region and a second sub-region. A deformation amount of the first sub-region is greater than a deformation amount of the second sub-region when the color filter substrate is pressed. The color filter substrate, the display panel, and the electronic device of the present invention can increase a resolution and photographing effect of an under-screen camera.

Abstract: An alignment coating structure for a substrate includes at least one substrate, and each of the substrates has a blind via; an alignment plate has at least one opening; the alignment plate covers on the substrate; the opening corresponds to the blind via; and a printing mechanism for transferring polyimide liquid on the alignment plate to a region out of the blind via on the substrate according to a preset printing direction. An alignment coating method for a substrate, including disposing an opening on an alignment plate makes the opening face a blind via in alignment coating. This makes the location where the blind via will not be printed by polyimide liquid, thereby increasing the liquid crystal arrangement randomness of the location where the blind via is, making the optical path be scattered to a certain extent, thereby prevent from occurrence of a Newton's ring or a rainbow pattern.

Abstract: A polarizing plate and a liquid crystal display device are provided. The polarizing plate includes a polarizing layer, a short wavelength band blue light film, a supporting layer, a release film, and a protective film. The short wavelength band blue light film is disposed on an upper side or a lower side of the polarizing layer. The supporting layer is disposed on a side of the polarizing layer opposite another side of the pluralizing layer facing the short wavelength band blue light film. The release film is disposed on a lower side of the polarizing layer. The release film is connected to the polarizing layer or the short wavelength band blue light film through an adhesive layer.

Abstract: A blind via hole region of a liquid crystal display panel is provided with a transparent support section, such that a cell thickness of the liquid crystal display panel from a display region to the blind via hole region is uniform, thereby prevents a Newton ring structure from affecting the imaging of a camera positioned below the blind via hole.

Abstract: The present invention provides a polarizing plate and a method of preparing the same, wherein the polarizing plate comprises a polyvinyl alcohol layer (PVA) and a support layer, the support layer is in contact with and supports the polyvinyl alcohol layer; wherein the support layer is a curing glue coating composed of at least one of a heat curing material, an optical glue, and a UV curing glue, and has a thickness of 5-20 ?m. The present invention adopts a novel structure design of a polarizing plate, and uses a curing glue coating to support and protect the polyvinyl alcohol layer. The curing glue coating can effectively reduce the thickness on the basis of realizing the same effect of an existing COP/TAC/CAT support layer, thereby reducing an overall thickness of the polarizing plate.
