Abstract

The invention discloses an embedded touch screen and a display device. A touch electrode pattern is arranged on one side, which faces an array substrate, of a surface of an opposite substrate; a common electrode layer is arranged above a data line and a grid line and below a touch electrode on the array substrate; and the grid line and the data line are completely shielded by the common electrode layer, so that disturbance of display signals of the grid line and the data line on touch signals can be reduced by the shielding effect of the common electrode layer, and disturbance of the touch signals of the touch electrode on the display signals can also be reduced by the shielding effect of the common electrode layer. A display function and a touch function can be simultaneously fulfilled by the touch screen in an embodiment of the invention; and various problems on displaying and touch due to time deficiency caused by time-sharing driving during high-resolution displaying are solved.

Description

technical field [0001] The invention relates to the field of display 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. In the touch screen, the touch electrodes of the touch screen are embedded in the liquid crystal display, which can reduce the overall thickness of the module and greatly reduce the production cost...
