Abstract

The invention provides a shift register unit, a driving method thereof, a shift register and a display device. The shift register unit includes a first shift register module and a second shift register module; the first shift register module includes: a first input module for inputting a start signal to the first control node; a second input module for inputting the first A level is input to the second control node; the first output control module inputs the second level to the first control node; the second output control module inputs the first clock signal to the second control node; the first output module , input the first clock signal to the first output terminal; and, the second output module, input the first level to the first output terminal; the second shift register module includes a second output terminal, a third input module , the fourth input module, the third output control module, the fourth output control module, the third output module and the fourth output module. The invention can reduce the number of transistors and is beneficial to realize narrow frame.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method thereof, a shift register and a display device. Background technique [0002] For the special timing requirements of OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays, it is necessary to set a normally-on shift register (light-emitting control shift register) in the pixel light-emitting stage to control the pixel light-emitting to be in the normally-on state. The structure of the light-emitting shift register currently used is relatively complicated, requiring many tube structures, which is not conducive to the design requirements of narrow-frame displays. Contents of the invention [0003] The main purpose of the present invention is to provide a shift register unit and its driving method, a shift register and a display device, so as to reduce the number of transistors and facilitate the realization of a narrow ...
