The capacitance type embedded touch screen comprises a substrate and a black matrix arranged on the substrate; the capacitance type embedded touch screen further comprises a first capacitance touch layer, an insulation layer and a second capacitance touch layer, the first capacitance touch layer is formed on the black matrix, the insulation layer is formed on the first capacitance touch layer, the second capacitance touch layer is formed on the first capacitance touch layer, and the first capacitance touch layer and the second capacitance touch layer are stacked and intersected in a grid shape. The invention further discloses a display device.

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] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in 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 an LCD screen with touch function. The production cost of the plug-in touch screen is relatively high. , low light transmittance, thicker 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...
