Problems solved by technology
[0004] Both the scanning driving circuit and the touch driving circuit in the above-mentioned non-display area need to occupy a certain layout area. After the touch electrodes are integrated on the array substrate, the width of the non-display area will inevitably be increased, making the frame area of the display panel larger. , unable to meet the user's demand for narrow borders

Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.
[0039] In order to solve the problem that after the touch function is integrated on the array substrate, it is necessary to set a driving circuit for touch control on the array substrate, which causes the width of the non-display area to become larger, which cannot meet the requirements for narrow borders. To realize the touch function, a large number of scan lines and I / O (input / output) ports need to be set separately. The embodiment of the present invention provides a technical solution to provide touch scanning signals for ...

An array substrate, a touch display panel and a driving method, where a driver circuit is in a non-display region of the array substrate, and the driver circuit includes: a first shift register including a first scan signal outputting terminal, where the first shift register is configured to output a first touch scan signal from the first scan signal outputting terminal within an interval between frame scanning periods of the array substrate; and a touch scanning circuit corresponding to the first shift register and including a first scan signal inputting terminal and a touch signal outputting terminal, where the first scan signal inputting terminal of the touch scanning circuit is connected with the first scan signal outputting terminal of the first shift register, and the touch scanning circuit is configured to output a touch signal from the touch signal outputting terminal thereof according to the first touch scan signal.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a touch display panel and a driving method for the array substrate. Background technique [0002] In the field of display technology, more and more products integrate display and touch on the same display panel, which can effectively reduce the thickness of the display panel, among which the in-cell touch display panel is the most prominent in reducing the thickness. [0003] The in-cell touch display panel integrates the touch electrodes on the array substrate, and is driven by the touch driving circuit arranged in the non-display area of the array substrate. However, in the non-display area of the array substrate, there are usually A scanning driving circuit, the scanning driving circuit mainly includes a shift register corresponding to each row of pixel units in the display area. During the frame scanning process, the shift register outputs a d...
