Abstract

The invention provides a touch screen, a manufacturing method and a display device, and relates to the technical field of touch technology. Working at the same time or working independently of original chirography electromagnetism handwriting and capacitance touch can be achieved. The market requirements of lightness and thinness can be met when the touch screen is used for the display device. The touch screen comprises a base plate, a plurality of first capacitance touch electrodes which are parallel with each other and are arranged on the same side of the base plate, a plurality of first electromagnetism touch electrodes which are parallel with the first capacitance touch electrodes, a plurality of capacitance touch electrodes which are crossed with the first capacitance touch electrodes and are parallel with each other, a plurality of second electromagnetism touch electrodes which are crossed with the first electromagnetism touch electrodes and are parallel with each other, and a protective layer arranged on the uppermost side. Different electrodes are not in electric connection with each other. The touch screen, the manufacturing method and the display device are used for manufacturing electronic equipment with a touch function.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch screen, a manufacturing method, and a display device. Background technique [0002] As a special computer peripheral, the touch screen can provide a human-computer interaction interface between the electronic system and the user, and has been widely used in many fields, for example, in mobile phones, personal digital assistants (Personal Digital Assistant, PDA), Game consoles, liquid crystal displays (Liquid Crystal Display, LCD), plasma displays (Plasma Display Panel, PDP), etc. [0003] At present, touch screens mainly fall into the following categories: electromagnetic touch screens, capacitive touch screens, electrical touch screens, and infrared touch screens. [0004] Among them, the capacitive touch screen generally adopts a front-attached type, and a capacitive touch driving electrode and a capacitive touch sensing electrode of a transparent conductive material (s...
