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 users' needs for narrow borders

Embodiment Construction

[0033] 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.

[0034] 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 ports need to be separately set up. The embodiment of the present invention provides a technical solution, which provides trigger signals and termination for...

Abstract

The invention discloses an array substrate, a touch display panel and a driving method for the array substrate, wherein the array substrate and the non-display area are provided with a driving circuit, and the driving circuit includes: a first shift register and a second shift register; A shift register includes a first display scan signal output end for outputting a first display scan signal, and a second shift register includes a second display scan signal output end for outputting a second display scan signal; the touch scan circuit, The first control terminal of the touch scanning circuit is connected to the first display scanning signal output terminal, the second control terminal of the touch scanning circuit is connected to the second display scanning signal output terminal, and the touch scanning circuit also includes a touch control The signal input terminal and the touch signal output terminal. In the touch stage, the touch scanning circuit controls the output of the touch signal through the touch signal output terminal according to the first display scan signal and the second display 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 control 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 out...
