  • Patent number: 10347203
    Abstract: Disclosed is a GOA drive circuit, including a plurality of GOA drive units. Each trigger unit in first K GOA drive units includes a first thin film transistor, which has a gate connected to a trigger clock corresponding to the trigger unit. The trigger clock is configured to turn off the trigger unit when a scan clock of an output unit corresponding to the trigger unit is at a high level.

  • Patent number: 10290717
    Abstract: The thin film transistor (TFT) contains a gate electrode metallic layer above a substrate, a gate insulator layer covering the substrate and the gate electrode metallic layer, a first source electrode metallic layer and a first drain electrode metallic layer above the gate insulator layer and separated by a gap, an active layer above the first source and first drain electrode metallic layers filling the gap and forming a ditch in the active layer above the gap, and a second source electrode metallic layer and a second drain electrode metallic layer above the active layer at two lateral sides of the ditch, respectively. The second source/drain electrode metallic layer contacts the first source/drain electrode metallic layer. The TFT has lower parasitic capacitance and takes up less area. As such, when the TFT is applied to a LCD, the reduced space consumed by the TFT enhances pixel's aperture ratio.
