Abstract

The invention discloses a gate drive circuit, a touch display device and a touch display drive method. The gate drive circuit includes: several GOA unit groups arranged in sequence, and the GOA unit group includes several cascaded mobile A bit register, a control unit is set between two adjacent GOA unit groups; the control unit is used to drive the corresponding gate line in the last stage of the shift register of the corresponding previous GOA unit group and after pre-set After setting the time, output the initial control signal in the high level state to the signal input end of the first stage shift register of the corresponding subsequent GOA unit group, to shift the first stage of the latter GOA unit group registers are precharged. The technical solution of the present invention can effectively ensure that the touch display screen can perform normal display in the display stage, and at the same time realize normal touch recognition in the touch stage.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit, a touch display device and a touch display driving method. Background technique [0002] The existing in-cell (IN-CELL) touch display screen has the advantages of good durability, high reliability, multi-touch, etc., and is widely used in the field of consumer electronics. [0003] The working process of the embedded touch screen generally includes a touch phase and a display phase. In the prior art, the touch phase of the touch screen can only be located in the blank time period between two adjacent frames. As the display resolution of the display screen increases, the blank time period between two adjacent frames will be compressed, so that the blank time period between two adjacent frames cannot meet the time required for driving in the touch stage. [0004] In order to solve the above-mentioned technical problems, existing manufacturers reduce ...
