An optical touch control system and an optical sensor thereof are provided. The optical sensor can be applied to a display having a display surface. The optical sensor includes a connecting frame, a light curtain module and a light emitter. The connecting frame has a first end portion and a second end portion opposite the first end portion. The light curtain module is disposed between the first end portion and the second end portion of the connecting frame. The light curtain module includes a light emitter electrically connected to the display so as to generate an invisible light curtain parallel to the display surface.
