| 摘要 |
The invention relates to a human-machine interface device (AP) having a transparent area (SD) for viewing a display screen (EC) and an access area (SND) in which there is at least one metal connector (CF) connected to at least two planes arranged above the display screen, said planes being: an electrode plane (E, PT) made of a transparent resistive conductive material, said plane being present in the transparent area, a conductor plane (G) made of a transparent resistive conductive material used as an active guard (G) for the electrode plane, said active guard being present in the transparent area and extending into the access area. The device according to the invention comprises at least one metal strip (PM), referred to as the guard strip (PM), for reducing the resistance of the guard, said guard strip being arranged within the access area (SND) and connected to the active guard (G) and to the metal connector (CF), the latter being connected to the electrode plane (E, PT) such that the conductor plane (G) and the electrode plane (E, PT) are at substantially the same potential. |
