Abstract
A touch screen including a housing, a display mounted in the housing, a plurality of collimating lenses mounted in the housing and arranged along a first edge of the display, a plurality of light pulse emitters mounted in the housing that are spaced apart from and serially transmit light pulses through the collimating lenses over the display, a light guide mounted in the housing along the edge of the display opposite the first edge, for receiving the light pulses, the light guide including a reflective strip that reflects light pulses to one end of the light guide, a light pulse receiver mounted in the housing near the one end of the light guide, for receiving the reflected light pulses, and a calculating unit, mounted in the housing and connected to the receiver, for determining a location of a pointer on the display that partially blocks light pulses transmitted by the emitters, based on outputs of the receiver.
