Abstract (en)
The keyboard has an outer layer (1) with a transparent area (2). A switching layer (3) has a switching unit, which lies below the area (2). An illuminant is arranged between the area (2) and the switching unit. The illuminant is formed from an organic light emitting diode (OLED), which is operated with a less direct current voltage of 12 or 24 volts. The diode is applied to a thin flexible support layer, which is arranged between the outer layer and the switching layer. The outer layer is made of plastics.
