Problems solved by technology

[0006] In the structure of the existing shift register unit, in order to ensure its normal signal output function, the internal thin film transistor needs to be on for a long time, which leads to an increase in the power consumption of the shift register unit. Moreover, the existing shift register In each frame time of the register unit, the gate signal input is pulled low for half of the time, and the gate signal output is in a floating state (floating) for the other half of the time, resulting in high noise in the existing shift register. Some damage to the shift register circuit

Abstract

A shift register according to the present disclosure may specifically include multi-level shift register units, a first connecting TFT set and a second connecting TFT set. In the multi-level shift register units, control signal input ends of odd-number-level shift register units are inputted with a first control signal and control signal input ends of even-number-level shift register units are inputted with a second control signal. Connecting TFTs in the first connecting TFT set and the second connecting TFT set are configured to achieve an electrical connection between gate electrode signal output ends of odd-number-level shift register units and even-number-level shift register units in the shift register under a control of a control signal transmitted by a timing controller.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register, a driving method thereof, and a display device. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. Moreover, thin film transistor (TFT, Thin Film Transistor) liquid crystal display has gradually become a standard output device for various data products due to its advantages of low operating voltage, no radiation scattering, light weight, and small size. [0003] A TFT liquid crystal display is generally composed of a matrix of pixels arranged in both horizontal and vertical directions. When a TFT liquid crystal display is displayed, a gate input signal is generated through a shift register, and each row of pixels is scanned sequentially from the first row to the last row. When designing a TFT liquid crystal display, it ...
