Embodiment Construction

[0040] 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.

[0041] 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.

[0042] An embodiment of the present invention provides an embedded touch screen, such as Figure 2a to Figure 2c As shown, it includes: including: an upper substrate and a lower substrate (not shown in the figure) arranged oppositely, a plurality of mutually independent self-capacitance electrodes 01 located on the side of the upper substrate facing the lower substrate or the side of the lower substrate facing the upper substrate, The wires 02 that are arranged in different layers with the respective capacitor electrodes 01 and are correspondingly electrically connected, and the in...

Abstract

The invention discloses an embedded type touch screen and a display device. An insulating layer is provided with at least a first via through the insulating layer in each area where respective capacity electrodes and wires are overlapped, the respective capacity electrodes are electrically connected with corresponding wires through the corresponding first vias, positions, corresponding to the first vias, of the respective capacity electrodes are provided with second vias in areas where the respective capacity electrodes and wires except the corresponding wires are overlapped, the second vias are through the respective capacity electrodes, and an orthographic projection of the second vias on a lower substrate covers an orthographic projection of the first vias on the lower substrate. According to the embedded type touch screen, on the basis that the first vias in the insulating layer are evenly distributed, correction connection of the respective capacity electrodes and the wires is guaranteed, so that the problem of uneven display images caused by uneven distribution of the vias in the insulating layer in the prior art is solved.

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 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 greatly reduce the production cos...
