Embodiment Construction

[0046]Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electr...

Abstract

The invention discloses an array substrate, a touch display panel and a display apparatus. The array substrate comprises a display region, a non display region surrounding the display region, a plurality of touch electrodes arranged in an array and including edge touch electrodes located in the edge position and non edge touch electrodes located in the non edge position, and a plurality of pixel electrodes arranged in an array and including edge pixel electrodes located in the edge position and non edge pixel electrodes located in the non edge position, wherein the edge touch electrodes extend to the non display region from the display region; the non edge touch electrodes are located in the display region; positive projection of a touch electrode on the array substrate covers positive projection of a plurality of pixel electrodes on the array substrate; and the shortest distance between one side, completely located in the non display region, in the edge touch electrode and the edge pixel electrode corresponding to the edge touch electrode is D1, and D1 is greater than or equal to 8um and less than or equal to 12um. According to the scheme, the potential uniformity of the touch electrodes can be improved and the touch performance of the edge touch electrodes can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to an array substrate, a touch display panel and a display device. Background technique [0002] With the continuous development of display technologies, touch screens have been widely used in people's daily life. [0003] According to the composition and structure, the touch screen can be divided into: Add on Mode Touch Panel, On Cell Touch Panel and In Cell Touch Panel. Among them, the built-in touch screen is to arrange the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and greatly reduce the production cost of the touch screen, and is favored by consumers and panel manufacturers. According to the working principle, the touch screen can be divided into: resistive touch screen and capacitive touch screen. Among them, the capacitive touch screen supports multi-touch function, has high light ...
