Embodiment Construction

[0039] The specific implementations 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.

[0040] The thickness and shape of each film layer in the drawings do not reflect the true ratio, and the purpose is only to illustrate the content of the present invention schematically.

[0041] The embodiment of the present invention provides an in-cell touch screen, such as Figure 2a to Figure 2c As shown, the upper substrate (not shown in the figure) and the lower substrate 01 arranged oppositely have a plurality of independent self-capacitance electrodes 02 arranged in a matrix. During the touch time period, the capacitance value of each capacitor electrode 02 is detected to change to A touch detection chip (not shown in the figure) for determining the touch position, and a plurality of wires 03 arranged in a different layer from the self-capacitance electrode...

Abstract

The invention discloses a built-in touch screen and a display device. In addition to including wires and self-capacitance electrodes, it also includes several sets of connecting wire groups arranged in different layers with the self-capacitating electrodes; each connecting wire group includes multiple sub-connections arranged at intervals Each segment of the connecting line belonging to the same connecting line group corresponds to a different self-capacitance electrode, and each segment of the connecting line is connected to the corresponding self-capacitance electrode through at least one via hole penetrating the insulating layer; when the wire and the self-capacitance electrode intersect No via hole is provided in the stacked area, and the wire is connected to the corresponding self-capacitance electrode through at least a section of sub-connection line connected to the corresponding self-capacitance electrode. The aforementioned in-cell touch screen ensures uniform distribution of the via holes in the in-cell touch screen by uniformly arranging the via holes in the areas corresponding to the sub-connecting lines. Therefore, the in-cell touch screen can solve the problem of uneven display images caused by uneven distribution of via holes in the insulating layer in the prior art.

Description

Technical field [0001] The present invention relates to the field of touch technology, in particular to an in-cell touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels have gradually spread throughout people's lives. At present, touch screens can be divided into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel according to their composition structure. Among them, the plug-in touch screen is produced separately from the touch screen and the liquid crystal display (LCD), and then bonded together to become a touch-sensitive LCD display. The plug-in touch screen has a higher production cost and a higher light transmittance. Shortcomings such as low and thicker modules. The in-cell 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 touch s...
