Abstract

The invention discloses a shifting register and a drive method thereof, a grid drive circuit and a display device. The shifting register comprises a precharge reset module, a downward-pull node control module, a plurality of output control modules and a plurality of output reset modules. The output reset modules correspond to the output control modules one to one. The output control modules are used for transmitting clock control signals in corresponding clock control signal lines to corresponding signal output ends under control of potential of upward-pull nodes. The output reset modules are used for resetting the signal output ends connected with the corresponding output control modules under control of potential of downward-pull nodes. The shifting register is provided with the signal output ends, the output control modules for controlling the signal output ends to output the signals and the output reset modules, the shifting register can be used for driving a plurality of grid lines, and therefore the shifting register can achieve design of an ultra-narrow frame when applied to a display panel.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a shift register, a driving method thereof, a gate driving circuit and a display device. Background technique

[0002] The basic principle of TFT-LCD (Thin Film Transistor-Liquid Crystal Display, thin film transistor liquid crystal display device) to realize a frame display is to input a square wave of a certain width to each row of pixels sequentially from top to bottom through the gate (Gate) drive. Strobe, and then drive the signal required for each row of pixels through the source (Source) and output from top to bottom in turn. At present, the display device with such a structure is usually made of gate drive circuit and source drive circuit on the glass panel by COF (Chip On Film, chip-on-film) or COG (Chip On Glass, chip directly fixed on the glass) process. However, when the resolution is high, the output of the gate drive circuit and the source drive circuit will increa...
