  • Patent number: 11215860
    Abstract: A display panel and a touch display device are provided. The display panel includes a thin film transistor substrate, a planarization layer, and a through hole. The through hole exposes a source/drain electrode of the thin film transistor substrate. A first intermediate layer, a metal wire layer, a second intermediate layer, a first common electrode layer, a first passivation layer, and a first pixel electrode layer are stacked on each other and arranged corresponding to the source/drain electrode at one side of the through hole. A second common electrode layer, a second passivation layer, and a second pixel electrode layer are stacked on each other at another side of the through hole. The first common electrode layer is electrically connected to the metal wire layer, and the first pixel electrode layer is electrically connected to the second pixel electrode layer through and along the through hole.

  • Patent number: 11209680
    Abstract: A liquid crystal panel and a method for manufacturing the liquid crystal panel is provided. The liquid crystal panel includes an upper substrate and a lower substrate disposed opposite to each other, a plurality of color resistances disposed on a side of the upper substrate facing the lower substrate, and a frame adhesive and a liquid crystal layer disposed between the upper substrate and the lower substrate; a plurality of display regions are enclosed between the upper substrate and the lower substrate by the frame adhesive; each display region includes one color resistance, each color resistance includes one numerical hollow pattern, and the numerical hollow pattern of each color resistance is not same as others; the liquid crystal layer includes a plurality of liquid crystals disposed in the display regions; a clearing point temperature of the liquid crystal of each different display region is not same as others.

  • Publication number: 20200249523
    Abstract: A color filter substrate includes a display area and a non-display area, in a pixel arrangement direction. The display area includes a first region in contact with the non-display area, and a second region not in contact with the non-display area. Opening ratios of pixels in the first region are smaller than opening ratios of pixels in the second region, such that the pixels in the region in the display area that is in contact with the non-display area and the pixels in the region in the display area that is not in contact with the non-display area have the same color mixing effects.

  • Publication number: 20200192149
    Abstract: A color filter substrate and a display device are provided. The color filter substrate includes a base substrate, a black matrix on the base substrate, and multiple pixel units arranged in the black matrix. The pixel units are arranged as multiple rows respectively. Each pixel unit includes a first sub-pixel, a second sub-pixel, and a third sub-pixel spaced from each other. Each of the first sub-pixels, the second sub-pixels, and the third sub-pixels has an opening area. Each of the pixel units of the first row and the last row is covered by the black matrix by a proportion larger than a proportion of each of the pixel units of the remaining rows covered by the black matrix.
