US 2011/0212661 A1 · METHOD AND APPARATUS FOR MANUFACTURING TOUCH SCREEN

Abstract

Disclosed herein is a method of manufacturing a touch screen, including: supplying a PET film; supplying and printing transparent conductive polymer electrodes on both sides of the PET film; printing conductive patterns on the transparent conductive polymer electrodes; supplying an adhesive to the transparent conductive polymer electrodes to form an adhesive layer; supplying a protective film to the adhesive layer; and cutting a laminate composed of the PET film, the printed transparent conductive polymer electrodes, the conductive patterns, the adhesive layer and the protective film. The method is advantageous in that a touch screen can be manufactured by an automated process using a roll-type feed or a sol-type feeder.
