Problems solved by technology

When the shift register units with such a structure are cascaded to form a gate drive circuit, the structure of the gate drive circuit can be as follows figure 2 As shown, since there are many TFTs in each shift register unit, the structure of the GOA circuit becomes complicated and occupies a large amount of layout space, which is not conducive to the narrow frame design of the display device

Abstract

The invention discloses a shifting register unit, a gate drive circuit and a display device to simplify the gate drive circuit and thus to reduce the size of the frame of the display device, and relates to the technical field of displaying. The shifting register unit comprises a latching module and at least two stages of output control modules which are connected with the latching module, the input end of the latching module is connected with a starting signal and a clock signal, the output end of the latching module is connected with the input ends of the at least two stages of output control modules, the latching module is used for latching the starting signal according to the input clock signal, the input end of each output control module is connected with the clock signal, the output control modules output grid line drive signals according to the clock signal, and the clock signal is input to the latching module and each stage of output control module according to a timing sequence.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a gate drive circuit and a display device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is composed of a pixel matrix defined by the intersection of gate lines and data lines in both horizontal and vertical directions. The gate (Gate) driver on the upper row inputs a square wave of a certain width from top to bottom to strobe each pixel row, and then through the source (Source) driver on the data line, the signal required by each row of pixels is sequentially transferred from Output from top to bottom, when the resolution is high, the output of the gate drive and source drive of the display will be more, and the length of the drive circuit will also increase, which will not be conducive to the bonding of the module drive circuit (Bonding) craft. [0003] In order to solve the above problems, the manufacture of exist...
