Embodiment Construction

[0023] At present, liquid crystal display technologies capable of realizing wide viewing angles mainly include In-Plane Switch (IPS, In-Plane Switch) technology and Advanced Super Dimension Switch (ADS, Advanced Super Dimension Switch) technology; among them, ADS technology passes through slits in the same plane. The electric field generated by the edge of the electrode and the electric field generated between the slit electrode layer and the plate electrode layer form a multi-dimensional electric field, so that all oriented liquid crystal molecules between the slit electrodes in the liquid crystal cell and directly above the electrodes can be rotated, thereby improving the operation of the liquid crystal. efficiency and increased light transmission efficiency. Advanced ultra-dimensional field conversion technology can improve the picture quality of TFT-LCD products, with high resolution, high transmittance, low power consumption, wide viewing angle, high aperture ratio, low co...

Abstract

The invention discloses a capacitance-type embedded touch screen, a driving method thereof and a display device. On a TFT (Thin Film Transistor) array substrate, two adjacent lines of pixel units form a pixel unit group, and a pixel structure with two grid signal lines are arranged between two lines of pixel units; and through altering the positions of grid signal lines of two adjacent lines of pixel units and a TFT switch, the position of the grid signal lines between the adjacent pixel unit groups can be saved, so that a touch driving line for realizing a touch function is arranged on the saved position of the grid signal lines, and a touch sensing electrode is arranged on a color film substrate and extends along the row direction of the pixel units, and thus the touch function is realized under the condition that high aperture ratio is ensured.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a capacitive embedded touch screen, a driving method thereof 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 re...
