Abstract

The invention discloses a gate drive circuit, a control method and a display device. The gate drive circuit comprises a primary pull-up drive unit, a primary pull-up unit, a primary pull-down drive unit, a primary pull-down unit, a secondary pull-up drive unit, a secondary pull-up unit and a secondary pull-down unit. The primary pull-up driving unit is connected with the primary pull-up unit, theprimary pull-down driving unit and the primary pull-down unit respectively; the primary pull-up unit is further connected to the primary pull-down unit and the secondary pull-up driving unit, the primary pull-down driving unit is further connected to the primary pull-down unit, the secondary pull-up driving unit is further connected to the secondary pull-up unit and the secondary pull-down unit, and the secondary pull-up unit is further connected to the secondary pull-down unit. According to the invention, the other stage of clock signal is enabled to be low and the pull-down tube is closed during one stage of output, so that interlocking of circuits during output is realized, and the effect of generating two stages of output signals through triggering of one triggering signal STU is realized at the same time.

Description

technical field [0001] The present invention relates to the technical field of displays, and more specifically, to a gate drive circuit, a control method thereof, and a display device. Background technique [0002] The current GOA (Gate Drive on Array) circuit used in the existing technology is as follows: figure 1 As shown, where Cout(n-1) is the Cout signal of the upper stage, CLK and CLKB are two complementary clock signals, and Cout(n+1) is the Cout signal of the next stage, this circuit can realize conventional shifting The bit register function, one GOA unit realizes the output of one gate signal line, but at present, with the continuous development of technology, it is necessary to compress the GOA unit when realizing technologies such as large-size and narrow borders. Contents of the invention [0003] The invention provides a gate driving circuit, a control method and a display device, which solves the problem that the existing technology is difficult to meet lar...
