Abstract

The invention discloses a shift register, a control method thereof and a display panel, and relates to the technical field of display. The shift register comprises: a first node control unit and a second node control unit which are used for respectively providing low level to a first node and a second node; a first inverting unit for providing a potential opposite to the potential of the first node to a third node; a second inverting unit for providing a potential opposite to the potential of the second node to a fourth node; and a first output unit and a second output unit which are used forsimultaneously providing opposite signals to the first output signal end and the second output signal end. The control method is used for controlling the work of the shift register. The display panelcomprises a plurality of pixel circuits, and the scanning drive circuit comprises a plurality of shift registers. The shift register can meet positive and negative pulse output at the same time, and the manufacturing size can be reduced while the driving capacity is met.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a shift register, a control method thereof, and a display panel. Background technique [0002] In the field of display technology, a thin film transistor (Thin Film Transistor, TFT) means that each liquid crystal pixel on a liquid crystal display is driven by a TFT integrated behind it, so as to achieve high-speed, high-brightness and high-contrast display screen information. In particular, large-size, high-resolution, and high-quality flat panel display devices, such as liquid crystal televisions, have occupied a dominant position in the current flat panel display market. With the development of the application technology of Organic Light-Emitting Diode (OLED) in the display screen, people have higher and higher requirements for the low power consumption performance of the display device, there are driving TFT and switching TFT and can realize lower Low Temper...
