Latest Patents

Kajiwara holds a patent for a touch panel controller and semiconductor device. This invention activates a touch panel that has a detection plane superposed on a display plane of a display device, enabling effective touch detection. The touch panel controller utilizes a cycle of 1/n (where n is a positive integer) of a display frame cycle on the display plane as the detection frame cycle of the detection plane. It determines the order of driving the detection-scan electrodes in each detection frame cycle based on predetermined phase-delay and phase-advance positions relative to the display-scan electrode drive position. This innovation allows for the avoidance of coincidence between display-scan and touch-detection positions, even when the detection frame cycle of the touch sensor is shorter than that of the liquid crystal panel.
