  • Patent number: 11901369
    Abstract: A pixel array substrate, including multiple pixel structures, multiple data lines, multiple scan line groups, multiple transfer line groups, multiple connection terminal groups, and multiple bridge line groups, is provided. The multiple data lines are electrically connected to the multiple pixel structures and arranged in a first direction. Each scan line group includes multiple scan lines arranged in a second direction. The multiple scan lines of the multiple scan line groups are electrically connected to the multiple pixel structures. Each transfer line group includes multiple transfer lines arranged in the first direction. The multiple transfer lines of each transfer line group are electrically connected to the multiple scan lines of a corresponding scan line group. The bridge line groups are structurally separated. Each bridge line group is electrically connected to a corresponding transfer line group and a corresponding connection terminal group.

  • Patent number: 9935132
    Abstract: A pixel structure including scan lines, data lines, and sub-pixels is provided. The scan and data lines are disposed on the substrate. The sub-pixels include switch devices, contact pattern layer, color filter pattern layers, and pixel electrodes. The switch devices are electrically connected to one scan line and one data line respectively. The contact pattern layer and the color filter pattern layer are disposed on the substrate and the switch devices. The contact pattern layer covers part of two adjacent switch devices. At least two color filter pattern layers include a patterned opening respectively, and the contact pattern layer is disposed in the patterned opening. The pixel electrodes are disposed on the color filter pattern layer, the contact pattern layer, and the switch device. At least one pixel electrode is partially disposed between the color filter pattern layer and the corresponding switch device while electrically connected to the switch device.

  • Publication number: 20160133173
    Abstract: A display panel includes a plurality of sub-pixels, scanning lines and data lines. The sub-pixels are disposed on a first substrate and include a plurality of rows and columns, and each sub-pixel of a first row of two adjoining rows is shifted by a predetermined distance along a first direction with respect to each sub-pixel of a second row of two adjoining rows. The scanning lines extend in the first direction and corresponding to the sub-pixels of the rows respectively. Each data line includes a plurality of first data segments and second data segments connected alternately. The first data segment extends along a second direction and partially overlaps the scanning line in a vertical direction. Each second data segment is disposed on one side of the scanning line, and at least a portion of the second data segments extends along a third direction different from the first and second directions.
