Abstract:
A method for generating an image described by contact, comprising:(a) providing a laminate, the laminate comprising at least one polymer thick film layer and including at least an outer receiving surface, a luminescent layer, and a translucent electrode layer, the receiving surface on the laminate separated from the translucent electrode layer by the luminescent layer; (b) coupling a power source to the translucent electrode layer and to a remote contact surface; (c) touching the receiving surface with the contact surface, wherein said touching is effective to selectively generate electric current through the laminate between the contact surface and the translucent electrode layer in a pattern in register with zones of contact between the contact surface and the receiving surface; and (d) responsive to said selective current generation, energizing the luminescent layer so as to generate light in said pattern.
