A user interface arrangement may include a printed circuit board having a first surface and a second surface, and a light emitting unit. The printed circuit board may include a first non-conductive layer provided with at least one aperture. The light emitting unit may be arranged to emit light through the at least one aperture of the first non-conductive layer in a direction from the second surface to the first surface of the printed circuit board to thereby define an image visible at the first surface of the printed circuit board. Embodiments of an electric apparatus comprising a user interface arrangement, a use of a printed circuit board to provide a user interface arrangement, and a method for visualizing an image on a user interface arrangement are also provided. |
