Abstract

The invention provides a control subunit. The control subunit comprises a low level input end, a gating module and N groups of nodes; each group of nodes comprises a first control node and a second control node; when the first control node in one group of nodes is at a high level, while the second control node is at a low level, the gating module is capable of switching on the second nodes of the rest (N-1) groups of nodes with the low level input end, so that the first and second control nodes in the rest (N-1) groups of nodes are all at the low level, wherein N is a positive integer greater than 1. The invention also provides a shifting register unit, a shifting register and a display device. Due to the added control subunits, a plurality of signals can be combined and no extra signal wire lead is required; as a result, the shifting register unit is capable of realizing signal combination, and the narrow frame design of a display panel also can be realized.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a shift register unit, a shift register comprising the shift register unit, a gate drive circuit comprising the shift register, and a gate drive circuit comprising the gate The display device of the drive circuit. Background technique [0002] Organic Light Emitting Diode (OLED), as a current-mode light-emitting device, is increasingly being used because of its characteristics such as self-luminescence, fast response, wide viewing angle and the ability to be fabricated on flexible substrates. In the field of high-performance display. OLED display devices can be divided into PMOLED (Passive Matrix Driving OLED, passive matrix driving organic light emitting diode) and AMOLED (Active Matrix Driving OLED, active matrix driving organic light emitting diode) according to different driving methods. Due to the advantages of manufacturing cost, high response speed, power saving, D...
