INFRARED RAYS TOUCH SCREEN APPARATUS OF WHICH TOUCH SENSING ACCURACY IS IMPROVED

摘要

PURPOSE: An infrared ray touch screen device which improved touch sensing accuracy is provided to exactly recognize a touch by removing a touch error by reflection light reflected by an infrared filter. CONSTITUTION: An X/Y-axis infrared transmission and reception elements(10,20,30,40) are arranged to face each other. A pair of X-axis frame(11) accepts the X-axis infrared transmission and reception elements. A pair of Y-axis frames(31) accepts the Y-axis infrared ray transmission and reception elements.
