Abstract

The invention discloses a shifting register, a drive method thereof, a drive circuit and a display device. The shifting register comprises an input unit, a reset unit, a control unit, a first output unit and a second output unit. The first output unit is used for controlling an output signal output by a first output end according to input signals of a fifth voltage end and a first clock signal end under the potential control of a first node and a second node. The second output unit is used for controlling an output signal of a second output end according to input signals of the fifth voltage end and a second clock signal end under the potential control of the first node and the second node. According to the shifting register, on the premise of not increasing control signals and ensuring functions of the shifting register, every two lines share the first node and the second node, and therefore the number of thin film transistors which are used is decreased, the occupied area of the thin film transistors is reduced, the structure of the shifting register can be simple, and the requirements for narrow frames and low power consumption are met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a driving method thereof, a driving circuit and a display device. Background technique [0002] In the existing array substrate row drive circuit (GateDriveronArray, GOA), each row of shift registers requires a pull-up node and a pull-down node, so that the number of thin film transistors is increased, and the occupied area of ​​the thin film transistor is large, resulting in a large area of ​​the array substrate. The structure of the row driving circuit is complex, which cannot meet the requirements of narrow frame and low power consumption. Contents of the invention [0003] In order to solve the above problems, the present invention provides a shift register and its driving method, driving circuit and display device, which are used to solve the problem that the number of thin film transistors used in the row driving circuit of the array substrate in the pr...
