Photoelectric touch panel having reflector and transparent photoconductive plate

摘要

A photoelectric touch panel characterized in that one side is provided with a substrate having light emitting elements and light sensing elements mounted thereon and an opposing side of the touch panel has a multi-directional reflecting surface for collecting dispersed portions of the light emitted by the light emitting elements. The multi-directional reflecting surface is joined with a photo-conductive body which guides the collected light back to the light sensing elements at the first side of the touch panel.
