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 actual scale, and are only intended to illustrate the content of the present invention.

[0041] The embodiment of the present invention provides an in-cell touch screen, such as Figure 2a to Figure 2c As shown in the figure, the upper substrate (not shown in the figure) and the lower substrate 01 are arranged opposite each other, and a plurality of mutually independent self-capacitance electrodes 02 are arranged in a matrix. A touch detection chip (not shown in the figure) for judging the touch position, and a plurality of wires 03 disposed in different layers from the self-capacitance electrode 02 and connecting the self-capacitance electrode 02 to the touch detection chip;...

Abstract

The invention discloses an embedded touch screen and a display device. The embedded touch screen comprises multiple connection wire groups arranged on a layer different from a layer where self capacitance electrodes are located besides guide wires and the self capacitance electrodes, wherein each connection wire group comprises multiple segments of sub connection wires arranged at intervals, each sub connection wire of each connection wire group is corresponding to each self capacitance electrode, each sub connection wire and each self capacitance electrode corresponding to each sub connection wire are connected through at least one via hole which runs through an insulating layer, no via hole is formed in an overlapped area of each guide wire and each self capacitance electrode, and each guide wire is connected with the corresponding self capacitance electrode through at least one sub connection wire connected with the corresponding self capacitance electrode of each guide wire. The embedded touch screen guarantees that the via holes are evenly distributed by evenly forming the via holes in the areas of the embedded touch screen, corresponding to all the sub connection wires. Accordingly, the embedded touch screen can solve the problem that display frames are not even, caused by uneven distribution of via holes in an insulating layer in the prior art.

Description

technical field [0001] The present invention relates to the technical field of touch control, and in particular, to an in-cell touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screens (Touch Screen Panel) have gradually spread throughout people's lives. At present, the touch screen can be divided into: an add-on type touch screen (Add on Mode Touch Panel), an overlay type touch screen (On Cell Touch Panel), and an in-cell touch screen (In Cell Touch Panel) according to the 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 form an LCD screen with touch function. The plug-in touch screen has higher production costs and higher light transmittance. Low, thick module and other shortcomings. The in-cell touch screen embeds the touch electrodes of the touch screen inside the liquid crystal ...
