Description

wear-resistant explosion-proof touch screen

Technical Field

The utility model relates to a the utility model belongs to the technical field of the touch-sensitive screen, specifically be wear-resisting explosion-proof touch-sensitive screens.

Background

In recent years, with the development of technology and technology, the number of electronic devices including a light-transmissive touch panel mounted on the front surface of a display element such as a liquid crystal display device has increased, and operators of such electronic devices operate the electronic devices by visually checking the display content of the display element located on the back surface of the touch panel through the touch panel while and by pressing the touch panel with a finger or a pen , for example, the operating devices of industrial and mining enterprises are increasingly equipped with touch panels for operation.

The touch-sensitive screen divide into capacitive screen and resistance screen two categories, because the operational environment of industrial and mining enterprise is more abominable, and the operator like all adopts and wears the gloves operation, this operational environment who just annotates industrial and mining enterprise adopts the resistance screen as the touch-sensitive screen to operate mostly, contains the dust in the environment in the industrial and mining enterprise, can accelerate the wearing and tearing degree of resistance touch-sensitive screen, but also can have the risk of being broken up by the dust, so it is necessary to provide wear-resisting explosion-proof touch-sensitive screens.

Disclosure of Invention

The utility model aims at providing wear-resisting explosion-proof touch-sensitive screens for solving the above-mentioned problem.

The utility model achieves the purposes through the following technical proposal that the wear-resistant and explosion-proof touch screens are characterized by comprising an electrode substrate, a conductive layer, a silver wire layer, a conductive film and a circuit board, wherein the electrode substrate is made of explosion-proof glass substrate;

a conductive layer is arranged above the electrode substrate, and a ring-shaped silver wire layer is arranged above the conductive layer;

a plurality of contact points are uniformly distributed in the space in the middle of the silver wire layer, and a side below the silver wire layer extends out of the circuit board;

and a conductive film is arranged above the silver wire layer, and a silicon nitride coating is coated above the conductive film.

Preferably, the thickness of the conductive layer is 20 to 50 nm.

Preferably, the thickness of the silicon nitride coating is 40-80 nm.

Advantageous effects

The utility model has the advantages that:

the utility model discloses a nanometer silicon nitride transparent coating can play and prevent drawing wear-resisting effect, utilizes silicon nitride itself to have the high wear resistant characteristic of hardness, and nanometer silicon nitride transparent coating effectively avoids the touch-sensitive screen by the fish tail in the use.

This practicality still plays explosion-proof effect through the electrode substrate that increases explosion-proof glass substrate material.
