Apparatus for multi touch and proximated object sensing by irradiating light selectively

The multi-touch and proximate object sensing apparatus by selectively irradiating light is disclosed. Object sensing apparatus includes a hovering light source may be used for sensing a target image generated by the touch light source and an object close to the light waveguide for sensing a touch image generated by an object touching the light guide separately. The light guide, to emit the invisible light radiated from the hovering light source to the top of the light guides it is possible to improve the sensitivity of sensing the proximity object.
