<p><P>PROBLEM TO BE SOLVED: To reduce noise, vibration, etc., of a display system constituted by integration of an input device and a display device. <P>SOLUTION: A touch panel integrated type liquid crystal device (display system) 200 comprises a liquid crystal display device (display device) 220 and a touch panel input device (input device) 230 constituted including an upper electrode 101 (conductive thin plate) and a lower electrode (conductive thin plate) 102 which are fitted to the liquid crystal panel (display part) 221 of the liquid crystal display device and detect an input position from outside. This display system 200 has a liquid crystal display device driving part (display device driving part) 222 which drives the liquid crystal display device 220 and an improvement signal generator (signal application part) 204 which applies a sounding improvement signal having the same amplitude and phase as a driving signal applied from the liquid crystal display device driving part 222 to the liquid crystal panel 221 to the touch panel input device 230. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
