Abstract

A gate drive circuit, a control method thereof, and a display device are disclosed. The gate drive circuit includes a plurality of cascaded shift registers, and at least one coded control sub-circuit; wherein each stage of the shift registers is configured to transmit a received signal to a next stage of the shift registers and the coded control sub-circuit. The coded control sub-circuit is configured to receive a coded signal, and transmit a voltage at the first voltage terminal or the second voltage terminal to the drive signal output terminal according to a signal output from a shift register coupled to the control sub-circuit under the control of the coded signal.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit, a control method thereof, and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) or Organic Light Emitting Diode (Organic Light Emitting Diode, OLED) display device as a flat panel display device, because of its small size, low power consumption, no Due to the characteristics of radiation and relatively low production cost, it is more and more used in the field of high-performance display. [0003] The gate lines of the above-mentioned TFT-LCD or OLED display device can be driven by a GOA (Gate Driver on Array, array substrate row driving) circuit. In the prior art, the holding time of a valid signal (such as low level or high level) in the output signal of the GOA circuit usually cannot be changed, so it cannot be flexibly adjusted according to the user...
