Embodiment Construction

[0035] The specific implementation manners of a touch screen and a display device provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] The thickness of each layer of film and the size and shape of the area in the drawings do not reflect the true proportion of the touch screen, but are only intended to schematically illustrate the content of the present invention.

[0037] A touch screen provided by an embodiment of the present invention, such as image 3 As shown, it includes: a capacitive touch sensing electrode 110, a capacitive touch driving electrode 120 that is insulated from the capacitive touch sensing electrode 110 and intersects with each other; it also includes:

[0038] The first electromagnetic touch electrode 210 is insulated from the capacitive touch sensing electrode 110 and arranged on the same layer;

[0039] The second electromagnetic touch electrode 220 is insulated from t...

Abstract

The invention discloses a touch screen and a display device. A first electromagnetic touch electrode and a capacitive touch sensing electrode are arranged on the same layer, a second electromagnetic touch electrode and a capacitive touch driving electrode are arranged on the same layer, it can be ensured that the electromagnetic touch control effect and the capacitive touch effect are ensured, meanwhile a film layer of the touch screen is simplified to a great extent, and therefore the thickness of the whole touch screen is reduced. In addition, in the manufacturing process, the first electromagnetic touch electrode and the capacitive touch sensing electrode are manufactured through the one-time picture composition process, the second electromagnetic touch electrode and the capacitive touch driving electrode can be manufactured through the one-time picture composition process, the manufacturing process can be simplified to the maximum extent, and the production cost of the whole touch screen can be saved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a 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 throughout people's lives. At present, touch screens can be divided into: resistive, capacitive, infrared, surface acoustic wave, electromagnetic, vibration induction, and frustrated total internal reflection optical induction, etc. according to their working principles. [0003] Among them, the capacitive touch screen is sought after by the industry as a new favorite due to its unique touch principle, high sensitivity, long life, high light transmittance and other advantages. At present, capacitive touch screens generally adopt the front-attached type, in which there are capacitive touch driving electrodes and capacitive touch sensing electrodes of mutually insulated transparent conductive mat...
