The invention provides a grid drive circuit, a display panel and a display device. The grid drive circuit comprises a first signal line, a second signal line, a control circuit and a plurality of cascaded shifting registers. The shifting registers are used for receiving first level signals transmitted by the first signal line and second level signals transmitted by the second signal line or receiving the second level signals transmitted by the first signal line and the first level signals transmitted by the second signal line, and the first level signals and the second level signals are opposite in level. An output end of the control circuit is connected with at least one of the shifting registers, a first input end is connected with the first signal line, and a second input end is connected with the second signal line. The control circuit is used for transmitting the first level signals inputted by the first signal line or the second signal line to the shifting registers so as to control the cascaded shifting registers to scan according to a first sequence through the first level signals, and accordingly a first voltage signal line and a second voltage signal line can be saved, and waste of the voltage signal lines is avoided.
Description
technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a gate drive circuit, a display panel and a display device. Background technique [0002] Existing display devices include a plurality of gate lines, a plurality of data lines, a pixel array, a gate drive circuit and a data drive circuit, wherein the gate drive circuit includes a plurality of cascaded shift registers, and each shift register The output end of the gate is connected with a gate line, and the data driving circuit is connected with a plurality of data lines. The gate drive circuit is mainly used to scan a plurality of gate lines through the shift register to scan the pixel array electrically connected to the gate lines by scanning the gate lines, and the data drive circuit is mainly used to output data to the data lines The driving signal is used to drive the pixel array to display the picture. [0003] The existing gate drive circuit inclu...
