Abstract

An embodiment of the invention provides a capacitor-embedded touch screen and a capacitor-embedded displaying device, and aims to solve the problem about common electrode split connection based on normal pixel design. The capacitor-embedded touch screen comprises an array substrate, grid lines, data lines and common electrode layers are arranged on the array substrate, wherein the common electrode layers comprise a plurality of touch driving element units and a plurality of touch sensing electrode units which are mutually insulated, the touch driving element unit comprise a plurality of touch driving sub-electrodes, the touch sensing electrode units comprise a plurality of touch sensing sub-electrodes, the touch driving sub-electrodes are connected with one of the touch sensing sub-electrodes in a bridging manner along the direction of the data lines and directly connected with the other touch sensing sub-electrode along the direction of the grid lines, or the touch driving sub-electrodes are connected with one of the touch sensing sub-electrodes in a bridging manner along the direction of the grid lines and directly connected with the other touch sensing sub-electrode along the direction of the data lines.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a capacitive embedded touch screen and a display device. Background technique [0002] A touch screen is an input device that allows a user to directly use a hand or an object to input a user's instruction by selecting an instruction content displayed on a screen such as an image display. The selected icon has commands to drive the liquid crystal display device to achieve a specific display. [0003] Existing touch screens are mainly divided into two types: external type and built-in type according to their different positions on the liquid crystal display; among them, the built-in type touch screen is set inside the panel of the liquid crystal display device, which can greatly reduce the The thickness of LCD products. At present, there are many design schemes for the display device of the embedded touch screen. Generally, one or two layers of transparent electro...
