Touch screen with bacteria inhibition layer and manufacturing method thereof

Abstract

The present invention is to provide a touch screen having a bacteria inhibition layer for prohibiting bacteria from growing thereon and a method for manufacturing the same comprising uniformly dispersing particles of nano metal material in a solution to be applied to a surface treatment so that the solution can have a concentration of 20 ppm to 500 ppm; evenly spray coating the solution on a screen of the touch screen; and subjecting the solution coated on the screen of the touch screen to a heat treatment until solvent in the solution is completely evaporated so that the particles of the nano metal material are densely adhered to the screen of the touch screen to form a bacteria inhibition layer thereon.

Description

FIELD OF THE INVENTION [0001] The present invention relates to touch screens and more particularly to such a touch screen having a bacteria inhibition layer for prohibiting bacteria from growing thereon and a method for manufacturing the same. BACKGROUND OF THE INVENTION [0002] Electronics and computer technologies have made a significant progress in recent years due to booming of the Internet. Many compact, portable products are developed by electronic and computer product designers and manufacturers for fulfilling the urgent needs of vast consumers. Moreover, a number of significant, revolutionary modifications have been made with respect to input component or output component of any one of the products due to the consideration of user friendliness. The most important one of the modifications is the development of touch screen. In one aspect, a touch screen as a component of an electronic and computer product is adapted to show output characters or graphics thereon. In another asp...

Benefits of technology

"The present invention provides a method for manufacturing a touch screen with a bacteria inhibition layer. The method involves dispersing particles of nano metal material in a solution and spraying the solution onto the screen of the touch screen. The solution is then heat treated to evaporate the solvent and allow the particles to adhere to the screen, forming a bacteria inhibition layer. The method can be applied to various types of touch screens, such as IR, resistive, capacitive, or ultrasonic touch screens. The solution can be prepared using a milling or ultrasonic method. The touch screen can be coated using methods such as spin coating, dipping coating, spray coating, or rolling coating. The solution can be heat treated at low or high temperatures depending on the type of substrate used. The technical effect of the invention is to provide a touch screen with improved bacteria inhibition properties."

Problems solved by technology

However, bacteria may grow on the touch screen of an electronic and computer product since it is installed in a public place for user operation by touching the screen.

This is a great threat to hygiene and public health.

Thus, how to maintain a clean touch screen of one of many types of electronic and computer products installed in public places is a critical, important issue for authority of each public place.

However, organic material has a low melting point or boiling point and is easy to evaporate or decompose.

Thus, its bacteria inhibition capability only lasts for a short period of time.

Moreover, generally speaking, organic material is toxic.

Hence, it is not appropriate to coat organic material on a product designed to be touched by users.

However, UV-light is very weak in a room environment.

Thus, the desired bacteria inhibition effect is substantially compromised.
