Shifting register and driving method thereof, grid integrated driving circuit and display device

Abstract

The invention discloses a shifting register and a driving method thereof, a grid integrated driving circuit and a display device. The shifting register comprises an input control module, a first output control module, a pull-up control module, a first pull-down control module and a second output control module. Therefore, by means of the arrangement of the first output control module and the second output control module, high level signals and low level signals can be provided, the first output control module and the second output control module intermittently work, and the service life of the shifting register is prolonged. In addition, through cooperating use of the pull-up control module and the second output control module, resetting of a signal output end can be achieved, and the arrangement of a reset module is omitted. In the grid integrated driving circuit formed by multiple cascaded shifting registers, the wire number of the grid integrated driving circuit can be reduced, the circuit structure is greatly simplified, and the design of a narrow frame of the display device is promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a driving method thereof, a gate integrated driving circuit and a display device. Background technique [0002] GOA (Gate on Array) is a technology that integrates the gate integrated drive circuit on the TFT substrate. The gate scan signal is provided to the gate of each switching transistor in the pixel area through the gate integrated drive circuit, and each switch is turned on row by row. The transistor realizes the data signal input of the pixel unit. [0003] Usually, in order to ensure that the GOA can provide a stable gate scanning signal for the display panel, the shift register, as a component of the gate integrated drive circuit, generally includes 15 switching transistors and at least one capacitor; and such a design often makes the circuit The structure is relatively complex and occupies a large area, which is not conducive to the design of narrow...

[0003] Usually, in order to ensure that the GOA can provide a stable gate scanning signal for the display panel, the shift register, as a component of the gate integrated drive circuit, generally includes 15 switching transistors and at least one capacitor; and such a design often makes the circuit The structure is relatively complex and occupies a large area, which is not conducive to the design of narrow borders; in addition, in the shift register, because some switching transistors are in the working state for a long time, it will not only cause the threshold voltage of the switching transistor to drift, but also reduce the switching performance. The service life of the transistor affects the normal operation of the shift register
