Embodiment approach

[0088] specific reference figure 2 The gate drive circuit shown, and Figure 6 The working timing diagram of the gate drive circuit provided, the embodiment of the present invention is as follows:

[0089] STV is the start signal, and each stage of shift register (including the shift register unit and virtual shift register unit provided in the present invention) uses the output signal of the output terminal of the upper stage as the start signal, in the double clock (CLOCK1 and CLOCK2) Working down, the first four shift register units SR1, SR2, SR3, and SR4 realize top-down gate drive scanning output G1, G2, G3, G4, then the clock signal stops and enters the touch time.

[0090] When the touch time is over, the clock signal is turned on again. When CLOCK1 is high, the output terminal of the virtual shift register unit SRD1 outputs a high level on GD1. When GD1 outputs a high level, the clock control terminal Rescan outputs a high level to turn on T1. , the high-level signa...

Abstract

An embodiment of the invention provides a grid driving circuit, a grid line driving method and a displaying device and relates to the technical field of displaying. The problem of poor displaying caused by scanning signal interruption in a time-share driving touch screen technique is solved. The grid driving circuit comprises a plurality of shifting register units which are in serial connection. A displacement delay module is in serial connection between the jth grade shifting register unit and the (j+1)th grade shifting register unit, the jth grade shifting register unit and the (j+1)th grade shifting register unit are adjacent to each other, the displacement delay module is connected with the output end of the jth grade shifting register unit and the input end of the (j+1)th grade shifting register unit, the displacement delay module is further connected with a repetition output module, and the repetition output module is connected with the output end of the (j-n+1)th shifting register unit and the control end of a clock. An embodiment of the grid driving circuit is applied to manufacturing displayers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gate drive circuit, a gate line drive method, and a display device. Background technique [0002] In touch screen technology, display scanning can be realized by time-sharing driving, that is, pixel scanning is performed in the driving phase, the output of the scanning signal is stopped in the touching phase, and the scanning signal is continued to be output to scan the pixels after the touching phase. In the technology, the gate drive circuit is usually composed of a plurality of shift register units connected in series, and each shift register unit corresponds to a gate line output driving signal, so in the output process of the above scanning signal, due to the long touch phase , The interruption of the scan signal output will cause the picture to be discontinuous, which will lead to poor display of the product.
