Abstract

The invention provides a shifting register as well as a driving method thereof, a grid electrode driving device and a display device, wherein a charging unit, an upwards pulling unit, a downwards pulling unit, a grid electrode signal input end, a DC (direct current) low-level signal input end, a grid electrode signal output end and first, second, third and fourth clock signal input ends are arranged in the shifting register, so that the grid electrode driving structure is simplified and the power consumption for driving a grid electrode is reduced.

Description

technical field [0001] The present invention relates to the display field, in particular to a shift register, a driving method thereof, a gate driving device and a display device. Background technique [0002] In the flat panel display, the basic principle of realizing a frame display is to output the data signal required by each row of pixels from top to bottom through the Source driver (source driver), and the Gate driver (gate driver) from top to bottom in turn A square wave with a certain width is input to each row of pixel gates for gating. [0003] In the existing production process, the gate drive IC (integrated circuit) and the source drive IC are bonded (bonded) on the glass panel through the COG (Chip On Glass, fixing the chip on the glass) process. [0004] However, in the existing gate driving structure, the output of the Nth row is mostly used as the reset signal of the N-1th row, which leads to the complexity of the existing gate driving structure and the prob...
