Abstract

The invention discloses a touch drive circuit, a display panel, a drive method of the display panel and a display device, and relates to the technical field of display. The touch drive circuit includes N stages of touch selection output units; a first signal input end of the touch selection output units is electrically connected with a touch signal end; a second signal input end of the touch selection output units is electrically connected with a common signal end, and a first control end of the touch selection output units is electrically connected with one gate line group; and a first control end of the nth-stage touch selection output unit is electrically connected with a second control end of the (n-1) th-stage touch selection output unit, and a first control end of the first-stage touch selection output unit is electrically connected with a second control end of the Nth-stage touch selection output unit. The touch drive circuit solves the technical problems that a corresponding display device is difficult to realize a narrow frame and the cost of an IC (Integrated Circuit) is increased due to a touch driving circuit in the prior art.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a touch driving circuit, a display panel, a driving method thereof, and a display device. Background technique [0002] With the development of modern electronic technology, corresponding components are provided in the display device to realize corresponding functions, such as touch functions, etc., so as to bring convenience to users. [0003] In the prior art, in order to realize the touch function, touch driving electrodes need to be provided in the display device. However, the touch driving circuit for providing touch driving signals to the touch driving electrodes is relatively complicated, which makes it difficult for the corresponding display device to realize narrow In addition, since the touch driving circuit has more signal input terminals, the touch driving circuit needs more output signals of an integrated control circuit (Integrated Circuit, IC for ...
