Abstract:
An optical reflective touch panel and pixels and a system thereof are provided. Each pixel of the optical reflective touch panel includes a display circuit and a sensing circuit. The display circuit controls the display of the pixel. The sensing circuit is coupled to the display circuit for sensing a sensitization state of the pixel during a turned-on period and a turned-off period of a backlight module and outputting a digital signal to notify an optical reflective touch panel system that whether the pixel is touched or not.
