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.
