Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] Please refer to Figure 4 , an embodiment of the present invention provides a gate drive circuit, including: a GOA signal drive module 1 , a selection module 2 and a GOA unit 3 . Wherein, the GOA signal driving module 1 is used to generate N road original driving signals, and transmits the N road original driving signals to the selection module 2, and the selection module 2 is used to receive the N road original driving signals transmitted by the GOA signal driving module 1, and N channels of original driving signals are processed to obtain M channels of GOA driving signals, and then the M channels of GOA driving signals are transmitted to the GOA unit 3 , where M is greater than N. Preferably, the value of M is twice the value of N, that is, M=2N.

[0027] The above gate drive circuit processes N original drive signals through the selection module 2, and outputs M...

Abstract

The invention provides a gate drive circuit and a liquid crystal display device. The gate drive circuit comprises a GOA signal drive module, a selecting module and a GOA unit, wherein the GOA signal drive module is used for generating N paths of original drive signals and transmitting the N paths of original drive signals to the selecting module; the selecting module is used for receiving the N paths of original drive signals transmitted by the GOA signal drive module, and processing the N paths of original drive signals, so that M paths of GOA drive signals are obtained, and then the M paths of GOA drive signals are transmitted to the GOA unit, wherein M is greater than N. For the gate drive circuit provided by the invention, after the N paths of original drive signals are processed through the selecting module, the M paths of GOA drive signals are output, M is greater than N, the original drive signals can be reduced under the premise that the drive effect is not influenced, thus hardware configuration of the gate drive circuit is simplified, and the drive cost and panel logic power dissipation are reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gate drive circuit and a liquid crystal display device. Background technique [0002] With the development of flat panel display technology, high resolution, high contrast, high refresh rate, narrow frame, and thinning have become the development trend of flat panel display. At present, liquid crystal display is still the mainstream product of flat panel display. In order to achieve narrow frame, thinner and lower cost of the liquid crystal panel, the development and application of the gate driver on array (GOA for short) is relatively mature. [0003] like figure 1 Shown is the GOA circuit architecture driven by 8 clocks in the prior art. Wherein the GOA unit circuit such as figure 2 As shown, it includes: a pull-up control module a, a pull-up module b, a pull-down module c, a pull-down maintenance module d and a pull-down maintenance module e. When G(N-5) is high poten...
