APPARATUS FOR OPTICAL TOUCH SCREEN

摘要

The present invention relates to an optical touch screen device including: a light source which generates light; and a plurality of beam splitters which reflect a portion of the light generated by the light source. Progression of light, reflected by some of the beam splitters, and progression of light, reflected by other beam splitters, are crossed over by each other. Therefore, location information of a pointing means can be exactly identified while the number of locations on which the light sources are installed.
