[0004] This requires setting the same number of shift register units as the touch drive electrodes in the shift register. However, since each shift register unit contains a large number of electrical components, the space it needs to occupy is correspondingly larger. It is not conducive to the realization of the narrow frame of the touch display panel

Abstract

The present invention discloses a touch display panel and a driving method thereof, and a touch display device. The touch display panel comprises a driving scanning circuit and m touch driving electrode units; the ith touch driving electrode unit includes ni touch driving electrodes, and the ni touch driving electrodes are divided into at least two touch driving electrode sets; the driving scanning circuit includes m driving circuit units and a shifting register with n cascaded shifting register unit; the kth touch driving electrode in each touch driving electrode unit is connected with the k-grade shifting register unit through the driving control unit, wherein the m and the ni are the integers of larger than 1, 1<=i<=m, the n is the maximum value in the ni, and the k is the positive integer of not larger than ni. According to the scheme, the touch display panels are divided into a plurality of touch driving electrode units, and each touch driving electrode unit uses the same shifting register so as to reduce the series of the shifting register unit and facilitate the realization of the narrow bezel.

Description

technical field [0001] The present application generally relates to the field of display technology, and specifically relates to a touch display panel, a driving method and a touch display device. Background technique [0002] The touch display device can detect the coordinate position of the finger in the display screen plane of the touch display device through two layers of touch electrode layers (for example, a touch driving electrode layer and a touch sensing electrode layer), and according to the coordinate position to display accordingly. [0003] Generally speaking, the integrated circuits of the touch display device sequentially apply touch driving signals to the touch driving electrodes. In order to reduce the number of ports through which the integrated circuit outputs touch driving signals to each touch driving electrode, in the prior art, a shift register is usually used to realize the step-by-step output of the touch driving signals. Such as figure 1 As shown...
