Abstract
An optical reflected touch panel and pixels and a system thereof are provided. Each pixel of the optical reflected touch panel includes a display circuit and sensing circuit. The display circuit is used to control displaying. The sensing circuit is coupled to the display circuit for sensing the sensitization state of the pixel at a turned-on period and a turned-off period of a backlight module and outputting a digital signal for notifying an optical reflected touch panel system as to whether the pixel is touched or not.
