Abstract

The invention discloses a shift register, a gate driving circuit and a display panel. The shift register comprises a pull-up module, a pull-down module, a reset module, a first control module, a second control module and an output module. By adopting the pull-up module, the pull-down module, the reset module, the first control module, the second control module and the output module, normal output of scanning signals can be realized. The output module of the shift register comprises two output ends which are connected with two adjacent gate lines, thus, one shift register disclosed by the invention can correspond to two gate lines, and the effect of inputting the scanning signals to the two adjacent gate lines by means of one shift register can be further realized. Compared with the situation that one shift register corresponds to one gate line in the prior art, the number of the shift registers can be reduced by half in the invention, thereby reducing the area occupied by the gate driving circuit on the display panel, saving the manufacturing cost and facilitating the implementation of the narrow-bezel design of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a gate drive circuit and a display panel. Background technique [0002] Currently, display technologies are widely used in displaying televisions, mobile phones, and public information, and display panels for displaying images are also various, and can display rich and colorful images. Generally, the source driver chip in the display panel is responsible for receiving image data, buffering the image data and converting the digital signal to an analog signal, and finally sending the converted signal to each data line of the display panel through the output buffer. The gate drive unit is responsible for realizing progressive scanning, and generates gate line scanning signals that are opened line by line for timing control. After loading the gate line scanning signals of each row to the corresponding gate lines, the pixel switches are controlled to open, so that t...
