Abstract:
The present invention relates to a camera module and an optical touch screen using the same, the camera module including an infrared emitting diode (100) for emitting infrared ray, a linear sensor (150) for detecting a touched area by detecting infrared ray reflected from a retro reflector, and an infrared pass filter (130) for passing the infrared ray emitted from the infrared emitting diode (100) and infrared ray incident on the linear sensor (150).
