Embodiment Construction

[0030] The specific implementation manners of the in-cell touch screen and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] The thickness and shape of each film layer in the drawings do not reflect the real scale, and the purpose is only to illustrate the content of the present invention.

[0032] figure 2 A schematic cross-sectional view of an in-cell touch screen provided by an embodiment of the present invention. An embedded touch screen provided by an embodiment of the present invention, such as figure 2 As shown, an array substrate 100 having a common electrode layer 110, and an opposite substrate 200 opposite to the array substrate 100;

[0033] like Figure 3a or Figure 3b As shown, the common electrode layer 110 of the array substrate 100 is composed of a plurality of touch driving sub-electrodes 111 and a plurality of common sub-electrodes 112 arranged i...

Abstract

The present disclosure provides an in-cell touch panel and a display device. An entire common electrode layer on an array substrate is divided so as to form a plurality of touch driving sub-electrodes and a plurality of common sub-electrodes spaced apart from each other and arranged alternately. The touch driving sub-electrodes are electrically connected to each other via a touch driving signal line so as to form a touch driving electrode, and the common sub-electrodes are electrically connected to each other via a common electrode signal line to form a common electrode. Touch sensing electrodes are arranged on an opposite substrate and cross the touch driving electrodes. The touch driving electrode is driven in a time-division manner, so as to achieve a touch function and a display function. The touch driving electrode consists of a plurality touch driving sub-electrodes and the common electrode also consists of a plurality of common sub-electrodes, so they have an approximately identical signal transmission load, and at a display stage, the common electrode signal is transmitted in the common electrode at a speed approximately identical to in the touch driving electrode. As a result, it is able to prevent the occurrence of an uneven display image, thereby to improve the image quality.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to 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 throughout people's lives. At present, touch screens can be divided into three types according to their structure: Add on Mode Touch Panel, On Cell Touch Panel, and InCell Touch Panel. 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 touch-enabled LCD screen. The plug-in touch screen has high production costs and low light transmittance. , The module is thicker 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 greatly reduce the production cost of the to...
