  • Patent number: 10126620
    Abstract: An array substrate, a manufacturing method thereof and a display device. The array substrate includes a base substrate; and gate lines and data lines disposed on the base substrate, in which the gate lines and the data lines are intersected to define pixel regions; thin-film transistors (TFTs) are disposed in the pixel regions; a color filter layer is disposed on the TFTs; the color filter layer includes: single-primary color resist sections disposed in the pixel regions and multi-primary color resist sections disposed in light-shielding regions; the single-primary color resist sections each include a color resist layer of one primary color; and the multi-primary color resist sections each include color resist layers to shield light. Thus, color filters can be formed on the array substrate, the number of patterning processes can be reduced, and the production cost can be lowered.

  • Patent number: 9904090
    Abstract: The present disclosure provides a touch display panel and a touch display device. The touch display panel includes a color filter substrate, an array substrate arranged opposite to the color filter substrate, and a liquid crystal layer arranged between the color filter substrate and the array substrate. Black matrices are arranged on the color filter substrate. A plurality of first electrodes made of metal is arranged parallel to each other on the color filter substrate, and a projection of each first electrode onto the color filter substrate in a perpendicular direction completely falls within a range of a corresponding black matrix. A plurality of second electrodes made of a transparent conductive layer is further arranged parallel to each other on the color filter substrate, and the second electrodes are insulated from, and cross, the first electrodes.
