Description

technical field [0001] The present invention relates to a gate drive circuit structure, and in particular to a gate drive circuit in a panel. Background technique [0002] With the advancement of technology, consumers have increasing demands on the resolution of liquid crystal displays, and in order to manufacture high-resolution liquid crystal displays, the industry gradually adopts a configuration method of gate-in-panel circuits. [0003] For example, in an eight-stage circuit structure adopting bidirectional scanning, the output signal provided by it is shown in FIG. 1 . It can be clearly seen from Figure 1 that the output signal Gout(n) overlaps with the output signal Gout(n+2). In detail, if referring to the output signal Gout(n) and the output signal Gout(n+1 ), nearly three-quarters of the parts overlap, which will cause the pixels to flicker, and in addition, the power consumption of the circuit will also increase. [0004] This shows that above-mentioned existing...

It can be clearly seen from Figure 1 that the output signal Gout(n) overlaps with the output signal Gout(n+2). In detail, if referring to the output signal Gout(n) and the output signal Gout(n+1 ), nearly three-quarters of the parts overlap, which will cause the pixels to flicker, and in addition, the power consumption of the circuit will also increase

[0004] This shows that above-mentioned existing mode obviously still has inconvenience and defective, and needs to be improved

In order to solve the above problems, related fields have tried their best to find a solution, but a suitable solution has not been developed for a long time.
