Abstract

The invention discloses a display panel and a gate driver. The gate driver includes a plurality of driving stages connected in series and outputs a gate driving signal. The driver stage includes an input unit, a driving unit and a pull-down unit. The input unit transmits the gate driving signal of the previous stage to the control node, and the gate driving signal of the previous stage includes a continuous first pulse and a second pulse. The driving unit outputs a gate driving signal according to the level voltage of the control node. The pull-down unit pulls down the gate driving signal to the first voltage after the enabling period of the second pulse. During the enabling period of the first pulse, the input unit pulls up the control node to the second voltage. After the enabling period of the second pulse, the driving unit pulls up the control node to a third voltage, and the third voltage is greater than the second voltage.

Description

technical field [0001] The present invention relates to a display panel (DISPLAY PANEL), in particular to a gate driver of the display panel. Background technique [0002] Recently, various liquid crystal display products have been quite popular. In order to effectively increase the viewing area of ​​the liquid crystal display, display panel technologies suitable for narrow bezels have been continuously proposed. [0003] However, as the resolution of the display continues to increase, the time that the gate driver can drive the display panel to charge becomes shorter and shorter. In order to maintain a certain pixel charging rate, the size of the multiple transistors in the gate driver must increase. In this way, the dynamic power consumption of the gate driver and the layout area of ​​the circuit will be increased, and it is more difficult to apply to the narrow frame application. [0004] Therefore, how to effectively reduce the circuit area of ​​the gate driver and at ...
