| 20100328243 | MEMS SCANNING TOUCH PANEL AND COORDINATE DECTION METHOD THEREOF - The present invention discloses a MEMS scanning coordinate detection method and a touch panel thereof, wherein the touch panel comprises a light source module, a MEMS reflector, an image sensor, an image signal processor, and a coordinate calculator. When the laser light from the light source module is reflected by the MEMS reflector, the laser light is transformed into a scanning light beam. When the touch panel is touched by a pen or a finger, the scanning light beam is blocked and two inactive pixels are formed on the image sensor. The electronic signal is transmitted from the image signal processor and calculated by the coordinate calculator to determine the touch point position. | 12-30-2010 |
