摘要
An optical plate structure for a touch panel includes an optical plate, at least a light source, and at least an optical camera. A light-emitting surface of the optical plate includes a plurality of micro-structure. The light source is disposed beside a vertical side of the optical plate and emits a first light entering the optical plate. The optical plate guides the first light and emits a second light from the light-emitting surface. The optical camera is disposed beside the optical plate or in a corner of the optical plate and above the light-emitting surface, for detecting a third light incident on the light camera. The second light is reflected by an object touching the optical plate to become the third light. The optical plate structure for a touch panel may be utilized in a touch display panel or a touch liquid crystal display panel.
