摘要： In a capacitance sensing analog circuit of a touch panel sensing circuit, by raising a magnitude of a current flowing through a sensing capacitor to form an amplified sensing capacitance, while sensing the amplified sensing capacitance with the aid of pulse width modulation signals, higher resolution of the original sensing capacitance may thus be achieved. Besides, by using a self-calibrating capacitance sensing circuit on the touch panel sensing circuit, linear errors and DC errors of an output signal of the capacitance sensing analog circuit may be filtered off, and thereby resolution of a capacitance amplifying ratio may be effectively raised so as to relieve errors within the capacitance amplifying ratio caused by noises.

摘要： A capacitance sensing circuit for a touch panel includes an analog capacitance-detecting circuit, a PWM-to-digital circuit and a self-calibration circuit. The analog capacitance-detecting circuit detects the capacitance of the touch panel based on a charging current, and converts the detected capacitance into a PWM control signal. The PWM-to-digital circuit converts the PWM control signal into a sensing count value based on a clock signal. The self-calibration circuit adjusts the value of the charging current or the frequency of the clock signal according to the difference between the range of the sensing count value and a predetermined detecting range. The predetermined detecting range can thus be adjusted for matching the range of the sensing count value.

摘要： A method of scanning a touch panel is provided. The present method includes following steps. First, a scan area is defined according to the coordinates of a detected touch signal. Next, the scan area is scanned during a predetermined period to detect a next touch panel. After the predetermined period, a sensing range of the touch panel is scanned to re-define the scan area. Because the scan area is smaller than the sensing range of the touch panel, the time and power consumed by the scanning operation can be both reduced by detecting the touch signals within the scan area.

摘要： A sensor structure of a touch panel and a method of determining a touch signal generated by the same are disclosed. The sensor structure includes a plurality of sensor lines disposed on a surface of a substrate, and a control circuit electrically connected to the sensor lines. Each of the sensor lines has a plurality of conductive pads and a conductive line electrically connected the conductive pads. The control circuit receives a touch signal from one of the sensor lines. The touch signal is resulting from a touch capacitance generated between a touch and one of the conductive pads of the sensor line. The control circuit calculates the position of the touch based on the touch capacitance. In addition, the touch capacitance generated by a conductive pad close to the control circuit is larger than the touch capacitance generated by another conductive pad further away from the control circuit.
