摘要：
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.
