Embodiment Construction

[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0030] Please see image 3 , image 3 It is a schematic structural diagram of an array substrate according to an embodiment of the present invention. The common electrode layer of the array substrate includes a plurality of touch driving electrodes 110 and a plurality of common electrodes 120 insulated from each other. The touch driving electrodes 110 and the common electrodes 120 intersecting; the touch driving electrode 110 includes a plurality of touch driving sub-electrodes 111 arranged along the extending direction of the touch driving electrode 110, each of the touch driving sub-electrodes 111 is located in the adjacent between the common electrodes 120 .

[0031] In the embodiment of the present invention, the common electrode layer connected to...

Abstract

The invention provides an array substrate, an embedded touch screen and a display device. A public electrode layer of the array substrate comprises multiple touch control driving electrodes and multiple public electrodes which are in mutual crossing and insulation arrangement; the touch control driving electrodes comprise multiple touch control driving sub electrodes arranged along the extension direction of the touch control driving electrodes; each touch control driving sub electrode is positioned between adjacent public electrodes; the array substrate also comprises touch control driving electrode serial lines; each touch control driving sub electrode belonging the same touch control driving electrode is electrically connected by at least one touch control driving electrode serial line; the touch control driving electrode serial lines are positioned in the display area of the array substrate; the extension direction of the touch control driving electrode serial lines is consistent with the extension direction of the touch control driving electrodes. The signal transmission loads of the touch control driving electrodes can be reduced and are enabled to be close to the signal transmission loads of the public electrodes, the problem of uneven display picture is avoided, the touch control driving electrode serial lines are arranged in a non-display area of the array substrate, and a narrow frame is favorably realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, an embedded touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Currently, touch panels can be classified into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel according to their composition and structure. Among them, the plug-in touch screen is produced separately from the touch screen and Liquid Crystal Display (LCD), and then bonded together to form a liquid crystal display with touch function. The plug-in touch screen has high production costs and low light transmittance. Low, thick modules and other shortcomings. The embedded touch screen embeds the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and gre...
