Abstract:
A photo sensing device suitable for an optical touch display panel and applications thereof are provided. The photo sensing device includes a photo sensing unit and a coupling unit. The photo sensing unit is used for sensing whether a touch event is happened/occurred or not, and accordingly outputting a judging signal. The coupling unit is coupled to the photo sensing unit, and is used for enhancing the sensitivity of the sensing unit, so as to increase a difference between the judging signal associated with occurrence of the touch event and the judging signal associated with non-occurrence of the touch event.
