Abstract:
1. A touch-sensing display apparatus, comprising: a display unit comprising integrated elements; a planar light guide located in front of the display unit, so as to define a touch surface; at least one light emitter arranged to emit light into the light guide for propagation by total internal reflection inside the light guide; and at least one light detector arranged to receive at least part of the light propagating inside the light guide; wherein the integrated elements comprise image-forming elements and touch-sensor elements, wherein the touch-sensor elements comprise at least one of said at least one emitter and said at least one detector and are arranged along a periphery region of the display unit, and wherein the image-forming elements and the touch-sensor elements together form a single integral structure in which the image-forming elements are only functionally separated from the touch-sensor elements.
