Patents by Inventor Qiaoqiao SONG

Qiaoqiao SONG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11437414
    Abstract: The present invention provides a display panel and a display device. A conductive film layer of the display panel is electrically connected to a gate electrode of a thin film transistor (TFT) through a first via hole, and the conductive film layer at least partially overlaps a source/drain electrode of the TFT to form a first capacitor. A second capacitor is formed in an overlapping region between a source/drain electrode of the TFT and the gate electrode of the TFT. Accordingly, a boost capacitance value of the display panel is increased, and a driving circuit requires less space.

  • Patent number: 10921666
    Abstract: An array substrate and a liquid crystal display panel are provided. The array substrate includes sub-pixel groups arranged in an array and each including first and second sub-pixels and a third switch assembly. The first sub-pixel includes a first main-zone electrode, a first sub-zone electrode, and a first switch assembly. The second sub-pixel includes a second main-zone electrode, a second sub-zone electrode, and a second switch assembly. The second switch assembly controls conduction of the second main-zone electrode and the second sub-zone electrode. The third switch assembly is connected to the first and second sub-zone electrodes and controls connection and conduction between the first and second sub-zone electrodes to reduce voltages of the first and second sub-zone electrodes. The array substrate helps reduce the number of switch units involved, simplifies the structure of pixels, lowers down fabrication cost, and also increases an aperture ratio of the liquid crystal display panel.
