PROBLEM TO BE SOLVED: To prevent disturbance of video image in a vehicle-mounted display by removing common mode noise effectively through a noise filter. SOLUTION: Between respective terminals 13-15, 17 of R, B, G, SYNC of a display 3, both terminals 19, 21 of VR and VG, and a display control circuit 28, a noise filter 29 is provided by winding coils 31-36 around a core 30 and respective terminals 13-15, 17, 19, 21 are connected with six coils 31-36. On the other hand, impedance is increased by increasing the cross-sectional area of the core 30 so that magnetic saturation is prevented. COPYRIGHT: (C)2006,JPO&NCIPI
