  • Patent number: 8970521
    Abstract: A method for identifying touch object on a touch panel has steps of (A) reading m capacitance variations on a first direction, wherein the m capacitance variations respectively correspond to m sensed units of the touch panel; (B) determining whether a difference between the capacitance variation of a kth sensed unit and that of another sensed unit exceeds a preset noise ripple, wherein k is equal to or smaller than m, m is a positive integer; (C) determining whether the capacitance variation of the kth sensed unit exceeds those of the adjacent sensed units; and (D) determining a touch stylus touched on the touch panel when the difference exceeds the preset noise ripple and the capacitance variation of the kth sensed unit exceeds those of the adjacent sensed units. Accordingly, the method can correctly identify a range touched by a stylus from the sensed signals combined with LCM noise signals.

  • Patent number: 8896570
    Abstract: A detecting method for a touch device, the method includes the steps of reading all sensed values of a frame associated with the touch device, computing a difference between a maximum sensed value and a minimum sensed value of all the sensed values of the frame, comparing the difference with a base value to generate a comparison result and executing a corresponding operation based on the comparison result.

  • Publication number: 20130076700
    Abstract: A method for identifying touch object has steps of presetting a range of slopes for noise signals, identifying multiple sensed signals, each having a slope higher than the range of slopes for noise signals in a sensing frame, and if the slope of each sensed signal is higher than an upper bound of the range of slopes for noise signals and is higher than each of those of the adjacent sensed signals, determining that the sensed signal is sensed from a corresponding sensed point touched by a stylus. Accordingly, the method can correctly identify a range touched by a stylus from the sensed signals combined with LCM noise signals.
