Abstract

The invention relates to a shift register, its driving method, and a gate drive circuit, and relates to the field of display technology. The main technical problem to be solved is that each stage of the shift register can only be used to drive one row of gate lines. The technical solution mainly adopted is: the shift register includes: an input unit, a first output part, and a second output part. The gate of the switch unit of the first output part is controlled by the output pole of the first pull-up unit, and the input pole of the switch unit is electrically connected with the output pole of the first output unit; the second output part includes a second pull-up unit, a second output unit, a second pull-down unit; the input pole of the second pull-up unit is electrically connected to the output pole of the switch unit, and the gate of the second output unit is controlled by the output pole of the second pull-up unit. Compared with the prior art, a single shift register can drive two gate lines, thereby effectively reducing the number of shift registers in the gate drive circuit, which is conducive to the miniaturization of the gate drive circuit and the narrowness of the display panel. frame.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a driving method thereof, and a gate driving circuit. Background technique [0002] The basic principle of TFT-LCD (Th i n Film Trans i stor-Liqu i d Crysta l Di sp lay, thin film transistor liquid crystal display device) to realize a frame display is to drive each frame from top to bottom through gate (Gate) A row of pixels is input with a square wave of a certain width for gating, and then the signal required to drive each row of pixels is output from top to bottom through the source (Source). [0003] However, in the existing gate drive circuit, each stage of shift register is triggered by a trigger signal to generate a shift register signal, and each stage of shift register can only be used to drive one row of gate lines, so the entire gate drive circuit It takes up a lot of space, which is not conducive to the realization of narrow borders. [0004] It c...
