Patent ID: 7683887

Claim:
A display system, which includes a display device and an input device, the input device being provided on a display section of the display device and having one or more conductive thin plates and being arranged to detect a position via which information is inputted from outside, said display system comprising: a display device driving section arranged to drive the display device; a signal application section arranged to apply, to the device having the one or more conductive thin plates, a noise canceling signal having an amplitude and a phase that are equal with an amplitude and a phase of a driving signal applied from the display device driving section to the display device; an input device control section to which a detection signal is applied, the detection signal being arranged to detect a position via which information is inputted from outside to the conductive thin plate; and a signal switching section arranged to select either the noise canceling signal or the detection signal so as to input the selected signal to the conductive thin plate.
