Embodiment 1

[0051] An embodiment of the present invention proposes a gate drive circuit, the gate drive circuit includes:

[0052] Multiple shift register units cascaded, see Figure 1(a), Figure 1(b) and Figure 1(c), Figure 1(a), Figure 1(b) and Figure 1(c) form a complete In the gate drive circuit, the clock signal terminal of each shift register unit has a corresponding clock signal input; the input terminal of the upper stage is connected to the output terminal of the next stage in turn, which means that the gate line drive signal is sequentially controlled by the clock signal It is transmitted in stages; and the output terminal of the next stage is also connected to the reset terminal of the previous stage, which means that after the next stage completes the transfer, the signal in the previous stage will be reset to prepare for the next signal transmission. It should be noted that the word "cascaded" in the gate drive circuit specifically refers to the connection relationship includi...

Embodiment 2

[0060] The embodiment of the present invention proposes a gate drive circuit with only two delay displacement modules, and the corresponding switch control module includes two sets of switching elements (two switching elements in each group), see Fig. 3(a) and Fig. 3(b) , Figure 3(a) and Figure 3(b) are a complete gate drive circuit, which includes, in addition to multiple cascaded shift register units:

[0061] The first delay displacement module 201, its input end is connected to the first end of the first switch element Q1, and its output end is connected to the input end of the Nth stage shift register unit;

[0062] The first switch element Q1, the second end of which is connected to the output end of the N-1th stage shift register unit;

[0063] The second switch element Q2, its first end is connected to the output end of the N-1st stage shift register unit, its second end is connected to the input end STV of the N+1st stage shift register unit, and the Nth stage shift r...

Embodiment 3

[0089] An embodiment of the present invention provides an array substrate, which includes a GOA (Gate On Array, gate array) area and a display area, and any gate driving circuit described in Embodiment 1 or 2 is disposed in the GOA area.

[0090] Since the array substrate provided in the embodiment of the present invention has the same technical features as the gate driving circuit provided in Embodiment 1 or 2, it can also solve the same technical problem and produce the same technical effect.

Abstract

The invention relates to the technical field of manufacturing of liquid crystal displays, and particularly provides a gate drive circuit, an array substrate, a display device and a driving method in order to solve the problem that in the prior art, because each frame of TSP signal is scanned at fixed time for acquisition, concealed wiring may happen in observation of human eyes. According to the gate drive circuit, the array substrate, the display device and the driving method, due to the fact that delay displacement modules are arranged in at least two different positions and whether the delay displacement modules work or not are controlled by a switch control module, the effect that preset time moments at which adjacent frame panels stop working temporarily are made to be different is achieved. Preset time moments at which touch screen panels in adjacent odd and even frame panels stop working temporarily can be made to be different, and therefore the problem that concealed wiring happens in observation of human eyes is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacturing, in particular to a gate drive circuit, an array substrate, a display device and a driving method. Background technique [0002] In recent years, the development of liquid crystal displays has shown a trend of high integration and low cost. Wherein a very important technology is exactly the realization of the technical mass production of GOA (Gate Driver on Array, array substrate line drive). The GOA technology is used to integrate the gate switching circuit on the array substrate of the liquid crystal display panel, thereby saving the part of the gate drive integrated circuit and reducing the product cost in terms of material cost and manufacturing process. The gate switch circuit integrated on the array substrate using GOA technology is also called a GOA gate drive circuit. [0003] In the gate drive circuit applied to the touch screen panel (Touch Screen Panel, TSP), in ord...
