Antistatic dustproof touch screen

Abstract

The invention discloses an antistatic dustproof touch screen. The touch screen comprises a base, a touch screen shell, watch glass and a static electricity dissipation plate, wherein a positive electrode is arranged on the base, a conducting layer is arranged on the positive electrode, an emission layer is arranged on the conducting layer, a negative electrode is arranged on the emission layer, aglass substrate is arranged on the negative electrode, and a capacitance layer is arranged on the glass substrate. An electrostatic protection layer is arranged in an original touch screen, wherein the electrostatic protection layer can dissipate static electricity generated by friction out of the touch screen, the frequency that a capacitor cannot send out a correct electric signal due to electrostatic interference is lowered, the sensitivity of receiving a user instruction is improved, better human-computer interaction is done, and the possibility that static electricity destroys the capacitor is lowered; and meanwhile, sealant is adopted to seal joints in the touch screen, so that damage to the inside of the touch screen by dust is reduced, and the service life of the touch screen is prolonged.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to an antistatic dustproof touch screen. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. Drive various connecting devices according to pre-programmed programs, which can be used to replace mechanical button panels, and produce vivid audio-visual effects through liquid crystal display screens. As the latest computer input device, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. [0003] During the use of the original touch screen, static electricity will be generated due to friction, which will absorb a large amount of dust and affect the life of the touch screen. At the same ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-static dust-proof touch screen to solve the problem that during the use of the original touch screen proposed in the above background technology, static electricity will be generated due to friction, which will absorb a large amount of dust and affect the life of the touch screen. At the same time, static electricity will cause The surface of the touch screen drifts, the signal processing of the capacitor collapses, the touch response is very slow, and the instructions specified by the user cannot be transmitted to the signal converter. When the static electricity content is high, the capacitor may be destroyed, resulting in damage to the touch screen and failure to work normally.
