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.

 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.    
   
   
       2 . The method of  claim 1 , wherein the nano metal material has biochemical activation, is capable of penetrating cell membrane of a bacteria for damaging enzyme and killing the same naturally, and has particles having a diameter in the range of about 1 nm to 100 nm.  
   
   
       3 . The method of  claim 2 , wherein the nano metal material is selected from a nano gold (Au), a nano silver (Ag), a nano copper (Cu), a nano zinc (Zn), or a nano platinium (Pt).  
   
   
       4 . The method of  claim 2 , wherein the nano metal material is selected from a combination or compound of a nano gold (Au), a nano silver (Ag), a nano copper (Cu), a nano zinc (Zn) or a nano platinum (Pt).  
   
   
       5 . The method of  claim 2 , wherein the solution to be applied to the surface treatment is for a hardening treatment, an endurability treatment, an anti-glare treatment, or an anti-reflection treatment.  
   
   
       6 . The method of  claim 5 , wherein a substrate of the touch screen is a PET film and the solution comprises UV-light resin or thermosetting resin and a predetermined solvent such that in response to evenly spray coating the solution on a surface of the PET film, the solution is subjected to a UV lamp radiation or a heat treatment depending on types of resin being used wherein the heat treatment is done in a temperature between about 50° C. and 100° C.  
   
   
       7 . The method of  claim 1 , wherein a substrate of the touch screen is a glass and the solution comprises silicate (ester), water, acid, and a predetermined solvent such that in response to evenly spray coating the solution on a surface of the glass, the solution is subjected to a heat treatment in a temperature between about 160° C. and 200° C.  
   
   
       8 . A touch screen comprising: 
 a screen; and    a bacteria inhibition layer coated on the screen to be touched by users and including a solution having particles of nano metal material and solvent completely evaporated to be applied to a surface treatment,    wherein the particles of the nano metal material are uniformly dispersed in the solution to be applied to the surface treatment so that the solution can have a concentration of 20 ppm to 500 ppm.    
   
   
       9 . The touch screen of  claim 8 , wherein the nano metal material has biochemical activation, is capable of penetrating cell membrane of a bacteria for damaging enzyme and killing the same naturally, and has particles having a diameter in the range of about 1 nm to 100 nm.  
   
   
       10 . The touch screen of  claim 9 , wherein the nano metal material is selected from a nano gold (Au), a nano silver (Ag), a nano copper (Cu), a nano zinc (Zn), or a nano platinum (Pt).  
   
   
       11 . The touch screen of  claim 9 , wherein the nano metal material is selected from a combination or compound of a nano gold (Au), a nano silver (Ag), a nano copper (Cu), a nano zinc (Zn) or a nano platinum (Pt).  
   
   
       12 . The touch screen of  claim 9 , wherein the solution to be applied to the surface treatment is for a hardening treatment, an endurability treatment, an anti-glare treatment, or an anti-reflection treatment.
