Abstract

The invention discloses a touch screen panel, a touch display panel and a display device. An electromagnetic shielding layer is arranged above wires, and projections of the wires on a first substrate are at least partially positioned in the range of the electromagnetic shielding layer. Therefore, the embodiment of the invention has at least one of the advantages that the influence of body capacitance on the wires in the range where the electromagnetic shielding layer is located can be shielded by the electromagnetic shielding layer, so that noise produced by the wires in the range of the electromagnetic shielding layer is eliminated to reduce the influence of the noise on the wires on touch sensing signals on touch electrodes and further increase the touch signal-to-noise ratio of the touch screen panel.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch screen, a touch display panel 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 ...
