Abstract
A resistive touch panel assembly is disclosed. An optical stack located within a housing includes an electronic display layer adapted to display an image and a resistive touch panel. The touch panel includes a number of touch input receivers placed adjacent to a first and second independently operable, grid sections which are located adjacent to one another in a seamless fashion. A number of input/output devices are in communication with the optical stack and extend through a channel comprising shielding.
