  • Patent number: 10969912
    Abstract: A capacitive sensing and sampling circuit and method thereof are disclosed. The capacitive sensing and sampling circuit has a voltage source, a sensing unit and a detecting circuit. The detecting unit has a first sensing output unit, a second sensing output unit and a sampling unit. The first and second sensing output units are electrically connected to an output of the sensing unit and the sampling unit. Therefore, by increasing the number of alternatively sensing the capacitive sensing component to obtain more capacitive signals, the number of sampling the sensed capacitive signal is relatively increased. Therefore, the white noise interference for the capacitive sensing and sampling circuit is effectively suppressed, so the signal-to-noise ratio is increased and accuracy of detecting coordinates of the touch object is increased.

  • Patent number: 10921942
    Abstract: A touch system has a touch device and an input device. The touch system executes a first mode and a second mode at different times. In the first mode, the touch device transmits a modulation signal to drive the touch electrodes and to be used as an uplink signal. The input device receives the modulation signal. In the second mode, the touch device receives the downlink signal from the input device. Thus, the touch device does not have to transmit the driving signal and the uplink signal at different times. Then the time is saved for the rest work periods so that every work periods get longer length of time.

  • Patent number: 9317157
    Abstract: A clustered scan method of a capacitive touch device has steps of simultaneously providing driving signals in one driving cycle to multiple driving lines including the (i?j)th drive line to the (i+k)th drive line, and simultaneously providing driving signals in a next driving cycle to the drive lines including some of the drive lines driven in the previous driving cycle with a sum of the driving signal in each driving cycle greater than zero. When the stimulated drive lines include a bordering drive line, the driving lines are determined according to a relationship among i, j and k. Accordingly, the signal to noise ratio of the touch device can be increased and the adverse effect for common ground occurring between a measuring system and a human body can be reduced so that the multi-finger positioning issue can be resolved.

  • Publication number: 20160098118
    Abstract: The present invention is related to a capacitive touch device and excitation signal generating circuit and method thereof. The excitation signal generating circuit is connected to multiple sensing traces of the capacitive touch device, and has a storage unit storing at least one set of digital data. Each set of digital data is corresponding to a frequency. The PDM signal generator reads the set of digital data and converts the read set of digital data to a PDM signal according to the frequency of the read set of digital data. The PDM signal is recovered to an analog excitation signal since the PDM signal passes through a current transmission path, which is equivalent to a low pass filter. Therefore, the present invention can decrease a distortion of the sensing signal to increase accuracy of the sensing signal and to save power.

  • Patent number: 9104279
    Abstract: A scan method for increasing frame rate of a touch panel having multiple driving lines, multiple sensing lines and a scan cycle with multiple detection cycles, has steps of generating multiple sets of asynchronous excitation signals within each detection cycle with each set of excitation signals outputted to a corresponding driving line, and receiving capacitance sensing values from the sensing lines corresponding to the driving lines. In contrast to conventional scan methods only outputting one set of excitation signals within each detection cycle, the time required to scan entire driving lines is greatly reduced and the frame rate is increased. Additionally, as the multiple sets of asynchronous excitation signals are asynchronous, the interference to the capacitance sensing values sensed by the sensing circuit in response to the multiple sets of excitation signals won't occur.

  • Patent number: 9069419
    Abstract: Methods are proposed for object positioning for an X-Y projected capacitive touch panel. In an embodiment, capacitance sensing under inphase excitation of traces is applied to set a base value when the capacitive touch panel is not touched and to obtain capacitances at intersections when the capacitive touch panel is touched, and the base value is compared with the measured capacitances to identify touch points. In other embodiments, X-Y projected sensing and all-point sensing are combined to reduce the amount of calculation and achieve the same positioning effect as an all-point capacitive touch panel.

    Abstract: A two-dimensional capacitive touch panel includes three electrodes made from a single sensor layer, with the first one of the electrodes between the other two of the electrodes to establish mutual capacitances between the first electrode and the other two, respectively. The mutual capacitance between the first and second electrodes increases along a direction, and the mutual capacitance between the first and third electrodes decreases along a direction. The first electrode is applied with an excitation signal for sensing variations in the mutual capacitances to calculate a position in the direction that is touched by an external conductor.

    Abstract: Two sensing units are configured as an exciter and a sensor connected to two trace lines, respectively, for mutual capacitance sensing from the capacitance units including these two trace lines. The two sensing units connect the two trace lines together to balance them to a same voltage level first, and then disconnect them from each other. Thereafter, the exciter connects the first trace line to an excitation node to induce a charge change on the second trace line, and the sensor senses the charge change to detect the variation of the mutual capacitance between the two trace lines.
