1. A method for estimating location of a touch object in a capacitive touch panel, the method comprising:

  • receiving, by a sensing circuit, raw data for detecting a touch object in a proximity of the capacitive touch panel, the raw data comprising a difference of a mutual capacitance value and a self-capacitance value at each of a plurality of touch nodes of the capacitive touch panel;

    processing, by a touch sensing controller, the received raw data to derive digitized capacitance data;

    classifying, by the touch sensing controller, the digitized capacitance data; and

    estimating, by the touch sensing controller, at least one of a location of the touch object on the capacitive touch panel and a distance of the touch object from the capacitive touch panel within the proximity using the classified capacitance data.
