Abstract

A display panel and a grid driver. The display panel includes a plurality of gate lines and a gate driver. The gate driver includes a plurality of driving stages connected in series, each driving stage includes an input unit, an output unit, a pull-down unit and a control unit. The input unit outputs a shifting signal to a first control node. The output unit generates a gate drive signal according to the shifting signal. The pull-down unit selectively pulls down the gate drive signal to a first preset voltage according to voltage potential of a second control node. The control unit includes an inverter which generates a control signal according to the shifting signal. In a disabled period of the control signal, the control unit pulls down the second control node to the first preset voltage. In an enabled period of the control signal, the control unit pulls up the second control node to a second preset voltage. The display panel can prevent the problem of voltage floating which causes operation invalidation, and has a relatively small circuit area.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a gate driver of the display panel. Background technique [0002] Recently, products of various liquid crystal displays have been considerably popularized. 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] figure 1 is a schematic diagram of a known shift register circuit 100 . The shift register circuit 100 is a common shift register circuit structure. Such as figure 1 As shown, the shift register circuit 100 receives the shift signal SS, and changes the voltage level of the control node A to generate the gate driving signal SR_OUT. [0004] In detail, when the previous stage shift register circuit 100 outputs the gate driving signal SR_OUT, the control node A of the present stage shift register circuit 100 will be pulled up to a high potential voltag...
