  • Patent number: 10379668
    Abstract: Embodiments herein describe input devices that include receivers for sampling capacitive sensing signals. In one embodiment, the receivers perform continuous demodulation where the sampling of the capacitive sensing signal is not synchronized with the modulated signal applied to the sensor. To calibrate, the receiver generates first and second measurements of the capacitive sensing signal when driving a modulated signal onto one or more sensor electrodes during two respective time periods. However, the phase of at least one signal is controlled during the time periods so that the first and second measurements have a phase difference of ninety degrees. Using the first and second measurements, the receiver can determine a phase offset between the capacitive sensing signal and the modulated signal which can be used to alter future measurements so that at least some of these measurements are captured when the capacitive sensing signal is at a peak amplitude.

  • Patent number: 10380965
    Abstract: The present invention relates to a power circuit of displaying device, which comprises a timing controller, a control circuit, and a charge pump (single or multiple stages). The timing controller outputs a timing control signal to the control circuit. The control circuit outputs a clock signal or a capacitance adjusting signal according to the timing control signal. The charge pump receives the input voltage and outputs an output voltage according to the clock signal or the capacitance adjusting signal. The output voltage is provided to the scan driver for generating a plurality of scan driving signals. Accordingly, by increasing the rise rate of the output voltage of the charge pump in the voltage conversion time and reducing the rise rate of the output voltage close to the voltage holding time, the present invention can achieve the effect of reducing the power consumption.

    Abstract: A strain quantity obtaining unit is provided that obtains a strain quantity at an interval faster than variation in the strain to be detected and stores the maximum value of the strain quantity. When a touch coordinate is obtained at a predetermined sampling interval, if the maximum value of the strain quantity when the touch coordinate is obtained does not exceed a strain quantity threshold value, the touch coordinate is not caused to be effective. However, if the maximum value of the strain quantity when the touch coordinate is obtained exceeds a strain quantity threshold value, the touch coordinate is caused to be effective. If a touch coordinate is caused to be effective once, the touch coordinate is caused to be effective continuously until an instructing object is separated from an operation surface of a touch panel unit at a predetermined distance or more in a perpendicular direction.
