20120287081 | TOUCH SENSOR PANEL CONTROLLER AND SEMICODUCTOR DEVICE - 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. | 11-15-2012 |
20140092061 | SEMICONDUCTOR DEVICE AND ELECTRONIC DEVICE - 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.

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.

20140210750 | TOUCH PANEL CONTROLLER AND SEMICONDUCTOR DEVICE - 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.
