33. A process for the creation of a flexible laminate membrane for a resistive touch screen, the flexible laminate membrane having a glass layer and a polyester layer, the process comprising the steps of:
-
applying an optical adhesive to said glass layer;
affixing a polyester layer over said optical adhesive;
rolling said optical polyester layer from the center of said polyester layer outwards to remove excess optical adhesive and air bubbles; and
pressing said polyester layer, glass layer and optical adhesive combination in a high pressure press to ensure a uniform level of optical adhesive. - View Dependent Claims (34, 35)
