Abstract:
A multi-touch and proximate object sensing apparatus using a wedge waveguide is provided. A multi-touch and proximate object sensing apparatus may sense a touch location or a target location on a display panel using a light which is reflected by an object located on the display panel. A camera in the multi-touch and proximate object sensing apparatus may sense the touch location or the target location from the light reflected by the object.
