Abstract

The present invention relates to a method to configure an illuminated surface on a device, and to generate illuminated patterns on a hard surface and to disclose an embodiment in an apparatus that applies the invention. The graphical patterns may include text and/or symbols as illuminated surfaces on the device. The invention may be used in all types of equipment and apparatus, where there is a demand for a high quality user interaction surfaces including graphics patterns on the surface, with a very nice looking expression/display.

First claim

The invention claimed is:

1. A method of providing a contrast area in a display surface, where said contrast area may contain graphical patterns, text, symbols, geometrical figures or other indications, where said display surface has an aluminum body, said body having a front side which in use is the display surface and a rear side, said method comprising the following steps:
a) working the display surface to the desired surface finish;
b) establishing a thin protective anodizing layer of between 2 and 6 μm;
c) providing one or more apertures by a laser machining process, in a desired display pattern, through the aluminum body and the protective anodizing layer;
d) removing the protective anodizing layer established in step b) by etching;
e) after step d), anodizing at least the display surface;
h) dyeing the anodized display surface in a desired pattern or area;
i) sealing the anodized and dyed display surface;
j) cleaning excessive dye from the display surface;
and
k) following step h) filling the apertures with a resin or acrylic and hardening said resin or acrylic.

2. The method according to claim 1 , wherein the dyeing in step h) is applied to the surface by silkscreen printing, inkjet printing or rollers, optionally using a mask and paintbrush or airbrush.
