Abstract

The invention discloses a capacitive in-cell touch panel and a display device. A transparent touch sensing structure layer is arranged on one side, facing towards a liquid crystal layer, of an opposite substrate opposite to an array substrate, and comprises first touch sensing electrodes and second touch sensing electrodes, wherein the first touch sensing electrodes and the second touch sensing electrodes are arranged in the same layer and mutually isolated. Mutual interference between a touch signal and a display signal in the array substrate can be avoided due to the fact that the touch sensing structure layer realizing touch is arranged on the opposite substrate far away from the array substrate; the quality of liquid crystal display frames is ensured; and the reliability of touch operation is improved. In addition, since the first touch sensing electrodes and the second touch sensing electrodes are arranged in the same layer in the touch sensing structure layer arranged on the opposite substrate, compared with that two layers of strip electrodes mutually crossed in different surfaces are manufactured respectively to serve as the touch sensing structure layer, the structure is relatively simple; the preparation technology steps can be shortened; and the production cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive 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 In Cell 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. 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 c...
