  • Patent number: 8497947
    Abstract: An LCD panel transmits the display data to sub-pixels in a zigzag pattern through a data line. The variation of the feed-through voltages of the sub-pixels may be modified by adjusting the ratios of the channel widths and the channel lengths of the TFTs in the sub-pixels to some predetermined ratios, or by adjusting the compensation capacitance to the coupling capacitance of the TFTs of the sub-pixels.

  • Patent number: 8279365
    Abstract: An active device array substrate includes a substrate, scan lines disposed on the substrate, data lines intersected with the scan lines, scan signal transmission lines, and pixel units. The scan signal transmission lines are intersected with the scan lines. Each scan signal transmission line connects one scan line through a node. The pixel unit electrically connects the corresponding data line and the corresponding scan line and includes an active device and a pixel electrode. The active device has a gate, a source, and a drain. The pixel electrode electrically connects the drain. In the pixel units not adjacent to the nodes, a gate-to-drain capacitance of each active device is Cgd1. In the pixel units adjacent to the nodes, the gate-to-drain capacitances of some active devices are Cgd2, the gate-to-drain capacitances of the other active devices are Cgd1, and Cgd1?Cgd2.

  • Patent number: 8421938
    Abstract: A pixel array is located on a substrate and includes a plurality of pixel sets. Each of the pixel sets includes a first scan line, a second scan line, a data line, a data signal transmission line, a first pixel unit, and a second pixel unit. The data line is not parallel to the first and the second scan lines. The data signal transmission line is disposed parallel to the first and the second scan lines and electrically connected to the data line. Distance between the first and the second scan lines is smaller than distance between the data signal transmission line and one of the first and the second scan lines. The first pixel unit is electrically connected to the first scan line and the data line. The second pixel unit is electrically connected to the second scan line and the data line.

  • Patent number: 8471973
    Abstract: This invention in one aspect relates to a pixel structure. In one embodiment, the pixel structure includes a scan line formed on a substrate and a data line formed over the substrate defining a pixel area, a switch formed inside the pixel area on the substrate, a shielding electrode formed over the switch, a plane organic layer formed over the date line and the pixel area and having no overlapping with the shielding electrode, and a pixel electrode having a first portion and a second portion extending from the first portion, and formed over the shielding electrode and the plane organic layer in the pixel area, wherein the first portion is overlapped with the shielding electrode so as to define a storage capacitor therebetween, and the second portion overlays the plane organic layer and has no overlapping with the data line.
