  • Patent number: 10783818
    Abstract: A dual gate transistor circuit, a pixel circuit, and a gate drive circuit are provided. The dual gate transistor circuit includes a dual gate transistor, a first diode, and a second diode. The dual gate transistor has a first gate and a second gate, and the first gate receives a drive signal. The first diode is connected in series between the first gate and the second gate according to a first-polarity direction. The second diode is connected in series between the first gate and the second gate according to a second-polarity direction. The first-polarity direction is opposite to the second-polarity direction.

  • Patent number: 8704220
    Abstract: An active device including a source, a drain, an oxide semiconductor layer, a gate and a gate insulator layer is provided. The source includes first stripe electrodes parallel to each other and a first connection electrode connected thereto. The drain includes second stripe electrodes parallel to each other and a second connection electrode connected thereto, wherein the first stripe electrodes and the second stripe electrodes are parallel to each other, electrically isolated, and alternately arranged, and a zigzag trench is formed therebetween. The gate extends along the zigzag trench. The oxide semiconductor layer is in contact with the source and drain, wherein a contact area among the oxide semiconductor layer and each first stripe electrodes substantially equals to a layout area of each first stripe electrodes and a contact area among each second stripe electrodes substantially equals to a layout area of each second stripe electrodes.

  • Patent number: 8698150
    Abstract: An active device, a driving circuit structure, and a display panel are provided. The active device includes a gate, a gate insulation layer covering the gate, a semiconductor layer disposed above the gate, an etching stop layer disposed on the gate insulation layer and the semiconductor layer, a source, and a drain. The gate forms a meandering pattern on a substrate. The semiconductor layer has an area substantially defining a device region where the active device is. The etching stop layer has a first contact opening and a second contact opening. The first contact opening and the second contact opening separated from each other and both exposing the semiconductor layer. The source and the drain separated from each other are disposed on the etching stop layer and in contact with the semiconductor layer through the first contact opening and the second contact opening, respectively.
