Touch-sensing display apparatus and electronic device therewith

摘要

A touch-sensing display apparatus comprises a display unit with integrated elements, and a planar light guide located in front of the display unit so as to define a touch surface. At least one light emitter is arranged to emit light into the light guide for propagation by total internal reflection inside the light guide, and at least one light detector is arranged to receive at least part of the light propagating inside the light guide. The integrated elements are designed as image-forming elements and touch-sensor elements, wherein the touch-sensor elements comprise the emitter(s) and/or the detector(s) and are arranged along a periphery region of the display unit. The image-forming elements and the touch-sensor elements may be integrated in one and the same composite substrate within the display unit.

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.
