Description

Switchable anti-ultraviolet capacitive touch screen

Technical Field

The invention relates to the technical field of touch screens, in particular to a switchable anti-ultraviolet capacitive touch screen.

Background

The liquid crystal used in the capacitive screen is an organic compound, and the stability of different structures is different. Ultraviolet absorption affects the photostability and lifetime of liquid crystal devices because high energy ultraviolet photons break the chemical bonds of long chain liquid crystal molecules, splitting occurs, and the molecular alignment becomes poor. The short-time irradiation of strong ultraviolet rays often shows a decrease in resistivity, an increase in power consumption, a yellowing of color, a decrease in clearing point, a darkening and a blackening of a screen, thereby degrading the performance of a liquid crystal display device.

In the prior art, most of capacitive screens generally do not have the ultraviolet-proof function, are easy to damage a liquid crystal panel when used outdoors, and reduce the service life. The practicability is lower.
