摘要：
An optical touch device includes a touch panel, an infrared light pen, and an infrared camera module. The infrared light pen emits infrared light towards a surface of the touch panel. The touch panel includes a display panel and an infrared reflective element. The infrared reflective element is stacked on the display panel and faces the infrared camera module. The infrared reflective element reflects the infrared light to the camera module. The camera module captures images of the infrared light reflected by the infrared reflective element.
