Shift register circuit and shift register

Abstract

The invention relates to a shift register circuit. The shift register circuit comprises a plurality of shift registers for outputting a plurality of drive pulse signals in turn, wherein in M shift registers for outputting M drive pulse signals in turn, the last shift register for outputting the drive pulse signals receives the enabling of (M-1) start pulse signals output by (M-1) shift registers for first outputting the drive pulse signals in turn to generate drive pulse signals, and M is a positive integer and more than 2. In addition, the invention also provides the shift register.

Description

technical field [0001] The invention relates to the field of display technology, and in particular to a shift register circuit and a shift register. Background technique [0002] Using amorphous silicon (a-Si) technology to make shift registers in the gate drive circuit of liquid crystal displays is the mainstream of thin film transistor liquid crystal display technology at present, which has the advantages of saving integrated circuit (IC) costs, simplifying the manufacturing process of modules and Advantages such as increasing the utilization efficiency of the glass substrate. Here, the shift register circuit includes a plurality of cascade-coupled shift registers to sequentially generate a plurality of driving pulse signals; start pulse signal. [0003] However, in some harsh environments, such as when the panel is operated at low temperature, the conduction current of the thin film transistor will drop sharply due to the temperature, so that the shift register circuit ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a shift register circuit, even if the conduction current of the transistor is low in a low temperature environment, it can still generate a driving pulse signal normally, so as to solve the problem of starting at low temperature
