A magnetic resonance (MR) safe touchscreen display (10) includes a touchscreen (16) and a film (30, 32) that has a high frequency shielding layer (20, 28) and a low frequency shielding layer (18, 26). A bus bar (14) conductively couples the low frequency shielding layer (18, 26) to the high frequency shielding layer (20, 28) around a perimeter of a face of the film (30, 32) and the edge of the film (30, 32). The film (30, 32) is adjacent to a rear face of the touchscreen (16). The bus bar (14) facilitates the connection of the touchscreen (16) and layers (18, 20) to the display (12) to form a Faraday cage around the display components contained within the display housing (11). |
