  • Patent number: 11094720
    Abstract: An array substrate and a display apparatus including the array substrate are provided. The array substrate includes a substrate divided into a display area and a peripheral area adjacent to the display area. A pixel array is formed on the substrate corresponding to the display area and receives a driving signal. A driving circuit includes a plurality of stages and is formed on the substrate corresponding to the peripheral area. Each of the stages includes a first transistor having a source electrode connected to an output terminal to output the driving signal, a channel layer formed between a gate insulating layer and the source electrode, the channel layer having an opening to facilitate contact between a portion of the gate insulating layer and the source electrode, and a capacitor defined by a gate electrode of the first transistor, the source electrode, and the gate insulating layer contacting the source electrode.

  • Patent number: 8928550
    Abstract: A driver chip for controlling a high-resolution display panel is presented. The driver chip is not much larger than a conventional driver chip that is currently used for lower resolution display panels. The driver chip applies data signals to the data lines of the display panel and gate control signals to a gate driver that is formed in the peripheral region of the display panel. The gate driver, which may be made of amorphous silicon TFTs, generates gate signals in response to the gate control signals from the driver chip and applies the gate signals to gate lines. Since the driver chip of the invention controls more gate lines and data lines than a conventional chip of about the same size, the driver chip may be easily adapted for display devices having multiple panels. Where multiple panels are used, the panels may be scanned simultaneously or sequentially.

  • Patent number: 8654055
    Abstract: A gate driving circuit includes a first shift register and a second shift register for driving odd gate lines. The first shift register includes a first plurality of cascade-connected stages that sequentially output a plurality of first gate signals. A first stage of the first shift register receives a first vertical start signal. The second shift register includes a second plurality of cascade-connected stages to sequentially output a plurality of second gate signals. The first stage of the second shift register receives an output signal of the first stage of the first shift register as its vertical start signal. A data charging rate may be improved by ensuring the timing margin of each gate signal, so that the driving reliability of the gate driving circuit may be improved.

  • Patent number: 7826000
    Abstract: An array substrate includes a base substrate, a dummy circuit section, a dummy pixel portion, an extended line, a common voltage line, and an overlap portion. Pixel portions are formed in a display area. The dummy circuit section is formed in a peripheral area to protect the pixel portions from static electricity. The dummy pixel portion is adjacent to the dummy circuit section. The dummy circuit section is in an electrically floating state. The extended line is extended from the dummy circuit section and electrically open with respect to the dummy pixel portion. The common voltage line is overlapped with the extended line of the dummy circuit section, the extended line being electrically open with respect to the display area, and thus the display area may be protected from the static electricity which flows into the dummy circuit section.
