Description

Touch screen with antibacterial function and its manufacturing method {TOUCH SCREEN WITH ANTI-MICROBIAL AND MANUFACURING METHOD THEREOF}

The present invention relates to a touch screen having an antibacterial function and a manufacturing method thereof.

As is well known, a touch screen is a type of input device that is provided on a monitor and inputs a specific command by inputting characters and/or pictures by simple contact using a finger or a pen.

The touch screen is usually used in bank ATMs, personal digital assistants (PDAs), navigation systems, kiosks, and the like.

When such a touch screen is used, germs and viruses on the finger may attach and proliferate, and there is a risk of spreading germs and viruses when used together.

Considering this point, an antibacterial layer having an antibacterial function is formed on the surface of some touch screens.

However, in the conventional touch screen in which an antibacterial layer is formed on the surface of the touch screen, there is a problem that the antibacterial function of the antibacterial layer is gradually weakened as the use time elapses, and the antibacterial function is easily lost when a certain period of time elapses. .

In consideration of these problems, some touch screens having an antibacterial function in which a protective layer or a buffer layer are formed on the inside and outside of the antibacterial layer, respectively, have been devised.

However, in a conventional touch screen having an antibacterial function, not only must an antibacterial layer be separately formed, but also a protective layer or a buffer layer for protecting the antibacterial layer must be additionally formed on the inside and outside of the antibacterial layer, respectively. There is a problem that the number of manufacturing steps increases.

In addition, as the antibacterial layer, the protective layer or the buffer layer is additionally formed, a lot of time and effort are required, so there is a problem that productivity is lowered.

In addition, since the antibacterial layer and the protective layer or buffer layer must be additionally formed on the surface of the glass panel, it is difficult to satisfy the optical characteristics of the touch screen.
