Abstract

The invention provides a shift register unit and a driving method thereof, a shift register and a display; the shift register unit comprises a first shift register module and a second shift register module; the first shift register module comprises the following elements: a first input module used for inputting an initial signal to a first control node; a second input module used for inputting a first level into a second control node; a first output control module used for inputting a second level into the first control node; a second output control module used for inputting a first clock signal into the second control node; a first output module used for inputting the first clock signal into a first output end; a second output module used for inputting the first level into the first output end. The second shift register module comprises a second output end, a third input module, a fourth input module, a third output control module, a fourth output control module, a third output module and a fourth output module. The number of transistors can be reduced, thus realizing a narrow frame design.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a shift register unit and a driving method thereof, a shift register and a display device. Background technique [0002] According to the special timing requirements of OLED (Organic Light-Emitting Diode, organic light-emitting diode) displays, it is required to set a normally-on shift register (light-emitting control shift register) in the pixel light-emitting stage to control the pixel light-emitting in a normally-on state. The structure of the currently used light-emitting shift register is relatively complex, and many tube structures are required, which is not conducive to the design requirements of the narrow-bezel type display. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a shift register unit and a driving method thereof, a shift register and a display device, so as to reduce the number of transistors and facilit...
