Abstract: A TFT, an array substrate, and a display panel are disclosed. The TFTs includes a gate, a first insulation layer arranged above the (late, a second insulation layer arranged above the first insulation layer, a semiconductor layer, a source, and a drain arranged between the first insulation layer and the second insulation layer, and a conductive layer arranged above the second insulation layer. The conductive layer and the gate are electrically coupled to each other such that when the TFT is in a turn-on state. A turn-on current generated in conductive channels of the semiconductor layer is increased. When the TFT is in a turn-off state, a turn-off current generated in the conductive channels is decreased. In this way, the ratio of the turn-on current to the turn-off current is increased.

Abstract: The invention provides a display panel and a gate driving circuit thereof including multiple stages of gate driving units. Each gate driving unit includes: a first pulling control circuit for outputting a first pulling control signal at a first node; a first pulling circuit for generating a gate driving signal according to the first pulling control signal and a first clock signal; a second pulling control circuit for outputting a second pulling control signal; and a second pulling circuit for pulling levels at the first node and an output terminal of the gate driving signal according to the second pulling control signal. A frequency of the second pulling control signal is lower than a frequency of the first clock signal but higher than a refresh rate of the display panel. The invention can prevent thin film transistor characteristic drift and thereby improve reliability of the gate driving unit.

Abstract: Disclosed are a pixel structure, an array substrate, and a display panel. In the pixel structure, a stabilizing line is configured to provide a stabilized signal to each pixel unit in a corresponding pixel unit group. When a high grayscale image is displayed, the stabilized signal provided by the stabilizing line is the same as a data signal received by a pixel unit in a turned-on state in the corresponding pixel unit group. Light transmittance and picture contrast of the display panel can be improved when the high grayscale image is displayed.
