Electromagnetic and capacitive dual-mode touch screen

Abstract

The invention discloses an electromagnetic and capacitive dual-mode touch screen which comprises a base material A and a base material B. One surface of the base material A and one surface of the base material B are both provided with a dual-mode touch layer, and the base material A provided with one dual-mode touch layer and the base material B provided with one dual-mode touch layer are assembled to form the dual-mode touch screen. Each dual-mode touch layer is internally provided with a capacitance inductor and an electromagnetic inductive loop, wherein the capacitance inductor and the electromagnetic inductive loop are located on the same horizontal plane. Inductive devices, namely the dual-mode touch layers, are arranged on the two base materials respectively, the placed inductive devices do not need to be processed on two sides, scratches are reduced, and the yield is increased. Compared with glass base materials, film materials are used in the base materials in the screen, so that the problem that films are likely to be broken and scratched during cutting does not exist. Besides, the base materials made of the film materials can well meet the requirement for light products.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an electromagnetic capacitance dual-mode touch screen body. Background technique [0002] In the prior art, the closest capacitive and electromagnetic dual-mode touch screen body is commonly known as G+G DITO structure or G+F2 DITO structure in the industry; among them, the G+G DITO structure is as follows figure 1 As shown, the structure of G+F2 DITO is as follows figure 2 shown. [0003] The biggest feature of this type of touch screen body is that the capacitive sensor and the electromagnetic sensor are respectively arranged on the upper layer and the bottom layer of the substrate, that is, the sensing device is respectively on the two sides of the same substrate, and the substrate used is usually glass; The disadvantages are as follows: [0004] 1. The base material is made of glass, which cannot meet the needs of light weight products; [0005] 2. Install induction d...
