    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.

    摘要: A touch sensing apparatus utilizes the characteristics of orthogonal vectors is disclosed. A random spread spectrum (RSS) signal or a periodic wave is used to modulate a driving signal so as to driving a row of a sensing array, and the RSS signal or periodic wave is also use to extract touch information of a node from a sensing signal measured from a column of the sensing array. The node is an intersection of the driven row and the measured column. When different RSS signals and/or periodic waves are used to drive multiple rows simultaneously, multipoint touching information can be obtained from the same sensing signal at the same time by respectively using the RSS signals and/or periodic waves to extract touching information of multiple points which are the intersections of the driven rows and the measured column.
