  • Method of applying a protective coating to a touch screen panel
    Patent number: 6406758
    Abstract: A method of applying a protective coating to a touch screen panel. A coating material which cures at an elevated temperature is applied to a touch screen panel on at least one surface thereof. The panel is then heated to a temperature which does not adversely affect the panel by irradiating the panel imparting energy to the coating material to more fully cure the coating material in a shorter time period without damaging the panel.
