Abstract

The invention discloses a shift register unit circuit comprising an input control module and an output drive module. The input control module is configured to receive an input control signal and store the input signal. The output drive module is coupled between the input end of a first clock signal and the output end of the unit circuit, and is configured to transmit the effective level of the first clock signal to the output end of the unit circuit under control of an input storage module. The output drive module includes a first transistor of which a first electrode is coupled to the input end of the first clock signal, a second electrode is coupled to the output end of the unit circuit, and a control electrode is coupled to the output end of the input control module. After the effective level of the first clock signal is output and before next effective level comes, the control electrode of the first transistor is coupled to the second electrode. The invention further discloses a gate drive circuit including the shift register, a corresponding display, and a method for providing a gate drive signal.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a gate drive circuit and a display device capable of suppressing clock feedthrough effects. Background technique [0002] Thin film transistor (thin film transistor, hereinafter referred to as TFT) is the core device of modern flat panel display technology. Whether it is the mainstream TFT liquid crystal display (TFT-LCD) or the rapidly developing active matrix organic light emitting display (AMOLED) display technology, the display driving array is composed of TFT pixel circuits. The quality of TFT electrical performance directly affects key indicators such as frame rate, resolution, grayscale, and image quality of the display. In recent years, with the rapid development of semiconductor materials, semiconductor manufacturing processes, automation equipment and other technologies, TFT technology has made great progress in terms of mobility, reliability, an...
