Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register circuit, an array substrate and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) includes a pixel matrix. During the display process, a gate scan signal is output through a gate drive circuit, and each pixel is scanned row by row. The gate drive circuit is used to generate the gate scanning signal of the pixel. GOA (Gate Driver on Array, array substrate row drive) is a technology that integrates the gate drive circuit on the TFT (Thin Film Transistor, thin film transistor) substrate. Each GOA unit serves as a shift register to sequentially transmit the gate scanning signal to the next GOA unit, and turn on the thin film transistor switches of the pixels row by row to complete the input of the gate scanning signal of the pixel. [0003] Since the working env...
