User interface arrangement
First Claim
1. A user interface arrangement comprising;
- a printed circuit board having a first surface and a second surface, anda light emitting unit,wherein (a) the printed circuit board comprises (i) a first non-conductive layer provided with at least one aperture, (ii) a second non-conductive layer, and (iii) a light diffuser layer arranged between the first non-conductive layer and the second non-conductive layer and (b) said second non-conductive layer is provided with at least one aperture arranged substantially in a position corresponding to a position of the at least one aperture of the first non-conductive layer on the printed circuit board, (c) the size and the shape of said at least one aperture of the second non-conductive layer substantially corresponds to the size and the shape of the at least one aperture of said first non-conductive layer, and (d) the light emitting unit is arranged to emit light through the at least one aperture of the first non-conductive layer and the at least one aperture of the second non-conductive layer in a direction from the second surface to the first surface of said printed circuit board to thereby define an image visible at the first surface of said printed circuit board.

Abstract
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.

12. A method for visualizing an image on a user interface arrangement, said method comprising the steps of;
-
providing a user interface arrangement, said user interface arrangement comprising a printed circuit board having a first surface and a second surface and a light emitting unit, said printed circuit board comprising a first non-conductive layer provided with at least one aperture and a second non-conductive layer provided with at least one aperture, and a light diffuser layer arranged between the first non-conductive layer and the second non-conductive layer, wherein the size and the shape of the at least one aperture of the second non-conductive layer substantially corresponds to the size and the shape of the aperture of the first non-conductive layer; and emitting light through said at least one aperture of the first non-conductive layer in a direction from the second surface to the first surface of said printed circuit board, whereby an image is visualized at the first surface of said printed circuit board.
