TOUCH SCREEN DISPLAY SYSTEM |
摘要 |
A touch screen display system combines the use of electromagnetic radiation emitters with shadow detection to determine the precise location or other touch related parameters of an object touching the display screen. In one embodiment the system comprises a display screen, a plurality of laser emitters disposed at a periphery of the display screen; a plurality of beam shapers to shape emissions from the emitters into fan beam patterns, and a plurality of detectors disposed at the periphery of the display screen to detect laser emissions of the laser emitters; and a processor to determine a location where an object touches the display screen, based on outputs of the detectors. |
