Embodiment Construction

[0014] The specific implementations of the capacitive 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.

[0015] The thickness and shape of each layer of the film in the drawings do not reflect the true ratio, and the purpose is only to illustrate the content of the present invention.

[0016] An embodiment of the present invention provides a capacitive in-cell touch screen, such as figure 1 As shown, it includes: a counter substrate 01, an array substrate 02, and a liquid crystal layer 03 located between the counter substrate 01 and the array substrate 02;

[0017] The side of the counter substrate 01 facing the liquid crystal layer 03 has a transparent touch sensing structure layer 04, and the touch sensing structure layer 04 is such as figure 2 As shown, it includes: a first touch sensing electrode 041 and a second touch sensing electrode 042 arranged in th...

Abstract

Embodiments of the present invention disclose a capacitive in-cell touch panel and a display device, with a touch sensing structure layer disposed on a side of an opposite substrate opposite to an array substrate, which side faces a liquid crystal layer; the touch sensing structure layer comprises a first touch sensing electrode and a second touch sensing electrode that are disposed in a same layer and mutually insulated; one of the first touch sensing electrode and the second touch sensing electrode is configured to be loaded with touch control scanning signals, and the other of the first touch sensing electrode and the second touch sensing electrode is configured to couple the touch control scanning signals and output. The touch sensing structure layer is provided on the opposite substrate that is away from the array substrate, which can avoid the mutual interference between touch control signals and display signals in the array substrate.

Description

Technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive 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 (Add on Mode Touch Panel), cover surface touch panel (On Cell Touch Panel), and in-cell touch panel (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 ...
