Disclosed herein is a projector sunshade for projecting an image of a logo onto a surface. The projector sunshade includes a UV-treated sheet, a first area on the UV-treated sheet including a shape of the logo, the first area being substantially transparent to light from an illumination source; and a second area surrounding the first area and including a lower transparency to the light relative to the first area.

An invisible, light-transmissive display system with a light resistant material is provided. Substantially invisible, tapered, light-transmissive holes are penetrated in a lighttransmissive pattern through at least a portion of the light resistant material using a laser beam having a focal width less than the smallest diameter of the tapered holes.

Embodiments are directed to an electronic device having a hidden or concealable input region. In one aspect, an embodiment includes an enclosure having a wall that defines an input region having an array of microperforations. A light source may be positioned within a volume defined by the enclosure and configured to propagate light through the array of microperforations. A sensing element may be coupled with the wall and configured to detect input received within the input region. The array of microperforations are configured to be visually imperceptible when not illuminated by the light source. When illuminated by the light source, the array of microperforations may display a symbol.

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.

Antimicrobial backlit devices and methods are provided. In one example embodiment, a device includes a backlight system configured to provide backlight for a display screen of the device. The backlight system includes one or more HINS light sources configured to emit HINS light and one or more non-HINS light sources configured to emit non-HINS light. The device further includes one or more control devices configured to control operation of the one or more HINS light sources and the one or more non-HINS light sources according to one or more light control profiles.

A lighting consists of a plate 3 to be illuminated and an elongated lighting element 1. The plate is provided with a first surface 5 in a first color and a second surface 7 in a second color. The lighting element 1 has an elongated housing 9 with a translucent wall, as well as a number of light sources 11 in the housing and distributed over the length of the housing. The lighting element 1 extends along the dividing line 13 between the two surfaces 5 and 7. The elongated housing 9 is provided with a first transparent wall part 15 facing the first surface 5 and a second transparent wall part 17 which at least partially faces the second surface 7. The first wall part 15 has the same or substantially the same color as the first surface 5 and the second wall part 17 has the same or substantially the same color as the second surface 7.
