摘要:
A ghost cancellation method for the multi-touch sensitive device is disclosed. The multi-touch sensitive device includes a sensing array having multiple lines of a first axis and multiple lines of a second axis intersecting with each other. All the lines of the sensing array are scanned to determine which ones of the lines are touched, so as to determine touch point candidates. For each touch point candidate, a driving signal is applied to the line of the first axis, and the line of the second axis is detected to check if the touch point candidate is actually touched.

A touch sensing method for detecting positions of touching is disclosed. In the present invention, a reference touch profile is provided. A variable ideal combination profile indicating multiple touches is obtained by synthesizing a plurality of reference touch profiles at different positions. The variable ideal combination profile is matched with a sensing signal. Actual touch positions can be identified from the sensing signal when the matching of the variable ideal combination profile with the sensing signal is optimal.

A touch detecting device comprises at least one driving circuit, a plurality of conductive lines and at least one sensing circuit. The originally available conductive lines of a touch panel are used to detect a finger touch by means of detecting a current leakage through the finger to the ground. Thus, the invention can reduce the hardware cost, avoid noise interference and correctly respond to a finger touch

A dynamic filtering device includes a variation detector, a coefficient generator and a filter. The cut-off frequency of the filter is dynamically adjusted according to variations of an input signal. A higher signal-to-noise ratio is obtained when a finger moves in slow motion and its response time is reduced when the finger moves in fast motion, therefore improving the response time and the noise immunity of the filter.
