  • Patent number: 9760222
    Abstract: Embodiments herein include a device, system, and method for periodically capturing sensing signals using one or more detection electrodes to generate data for detecting an object proximate to the detection electrodes. The sensing signals are captured during detection periods within periodic detection cycles where each of the detection cycles define a period of time between consecutive detection periods. In addition, the device, system and method set a duration of the detection cycle to 1/m (where m is appositive integer) of a duration of a display-scan cycle. The value of m is selected based on a periodic noise signal. Thus, the device, system, and method may prevent a periodic noise signal which has a cycle that is longer than the detection period from worsening the accuracy of touch detection.

  • Publication number: 20170162605
    Abstract: To make the dimension of an electrostatic protection circuit small with the same maintained high in sensitivity. The electrostatic protection circuit is of the configuration that a first diode and a second diode are connected in series, wherein a semiconductor layer owned by each diode is configured to be sandwiched between a gate electrode and a conductive light shielding film. The light shielding film is formed to overlap with the semiconductor layer and has a wider area than the semiconductor layer. This results in having a gate covering the semiconductor layer from an upper side and a back gate covering the semiconductor layer from a lower side, so that the sensitivity can be maintained high irrespective of decreasing the electrostatic protection circuit in dimension.

  • Patent number: 9568976
    Abstract: The semiconductor device has a touch panel controller, a processor and a display driver. The semiconductor device is arranged so as to reduce an electric power uselessly consumed while the action of the display driver is stopped or suspended and further, and an electric power uselessly consumed by the touch-detecting action for recovery of the display driver from the state of the action being stopped or suspended. The processor built in the semiconductor device together with the touch panel controller and the display driver returns to its workable state from Sleep state each time a given length of time elapses, and then causes the touch panel to perform a touch-detecting action. When the processor cannot acquire a result of judgment as “being touched”, it returns to Sleep state again, and waits for the given length of time to elapse.

  • Patent number: 9519385
    Abstract: The touch panel controller is connected with a touch panel having a plurality of drive electrodes, a plurality of detection electrodes, and a plurality of capacitance components formed at intersections of the drive and detection electrodes. A two-edge detection mode is adopted for the touch panel controller, in which signals arising on each detection electrode in synchronization with rising and falling edges of a drive pulse output to the drive electrodes, and alternately changing in polarity are accumulated in the integration circuit in terms of absolute value components. The integration circuit switches the connection of the integration capacitance between an input and an output before the drive pulse edge changing. The touch panel controller contributes to the shortening of the time for touch detection by the touch panel and the increase of the accuracy of touch detection.

  • Patent number: 9354741
    Abstract: The touch panel controller activates a touch panel having a detection plane superposed on a display plane of a display device, and performs a touch detection. The touch panel controller uses a cycle of 1/n (n is a positive integer) of a display frame cycle on the display plane as the detection frame cycle of the detection plane. The touch panel controller decides an order of driving the detection-scan electrodes in each detection frame cycle according to predetermined phase-delay and phase-advance positions with respect to a display-scan electrode drive position of the display device so as to correspond to an order of the detection-scan electrode array of the touch panel. The touch panel controller makes possible to avoid the coincidence of display-scan and touch-detection positions without thinning touch detections even with the detection frame cycle of a touch sensor shorter than the display frame cycle of a liquid crystal panel.

  • Patent number: 9250740
    Abstract: It becomes possible to use drive pulses having different pulse widths for one kind of drive pulse signal period. Therefore, even if a voltage acting on a crossing part of drive and detection electrodes is periodically changed through a stray capacitance attributed to an external object such as a finger in an undesired manner, the pulse width of the drive pulse is never fixed with respect to the period, and the periodic buildup of a certain voltage on a detection signal, which would make appreciable noise, is suppressed. Thus, the reduction of detection signals can be suppressed in quantity without switching the pulse signal frequency of the drive pulse of a touch panel.

  • Patent number: 9195352
    Abstract: Provided is a touch sensor panel which can increase the detection sensitivity of a touch relatively readily. The touch sensor panel controller supplies drive electrodes of a touch sensor panel with a high-voltage AC drive signal with its low level set to a negative voltage and drives them. The time of change of a drive waveform supplied to the drive electrodes of the touch sensor panel is shifted relative to the time of change of a drive waveform supplied to a display scan electrode. The touch sensor panel controller uses a charge pump in synchronization with clock signals of more than one phase to produce a high drive voltage to activate drive electrodes of the touch sensor panel, and the clock signals of more than one phase are initialized each time the drive electrode is subjected to AC pulse driving.
