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.

摘要： 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.

摘要： An electronic device includes a touch panel, a driving circuit, and a sensing circuit. The driving circuit generates a driving signal, and superposes phase information on the driving signal. The touch panel includes multiple crossing conductors, for providing a sensing signal in response to a contact of an object on one of the sensing conductors and to a driving signal applied on the sensing element. The sensing circuit includes a signal extractor and a tag detector. The signal extractor generates a demodulation signal based on the period of the driving signal, width of the phase information, and for demodulating the sensing signal by using the demodulation signal to determine a sensing value. The tag detector enables the signal extractor as soon as a magnitude of the sensing signal is over a predetermined threshold. The signal demodulates the sensing signal by using a demodulation signal whose period is the same as the driving signal to determine the sensing value. The present electronic device can determine a touch position by processing of analog signal using the demodulation signal without phase compensation.

摘要： A touch sensing device and method for detecting a touch event of a sensing array are disclosed. In the present invention, a random duration square wave signal is used to modulate a current or voltage signal so as to generate a modulated driving signal for driving a row of the sensing array. The random duration square wave signal has cycles of different durations so that the modulated driving signal also has the same cycles with the different durations. A sensing signal is measured from a column, for example, of the sensing array. Touching information is extracted by using the random duration square wave signal to demodulate the sensing signal.
