View Patent ↗An arrangement and method for displaying at least a first and a second image. The arrangement comprises at least one light source ( 120, 121, 220, 221, 320, 321 ) adapted to generate light having at least a first and a second light characteristic; and at least a first and a second image forming element ( 122, 123, 222, 223, 322, 323 ) arranged to display a first and a second image ( 128, 129, 230, 231 ), respectively. The first image forming element ( 122, 222, 322 ) is at least responsive to the light having the first light characteristic. The second image forming element ( 123, 223, 323 ) is at least responsive to the light having the second light characteristic.
1. An arrangement for displaying a first and a second image within a physical area of an input device for a man-machine interface, comprising
at least one light source adapted to generate light having a first and a second light characteristic; and
at least a first and a second image forming element arranged to display a first and a second image, respectively; wherein
the first image forming element is at least responsive to the light having the first light characteristic; and
the second image forming element is at least responsive to the light having the second light characteristic; and
a covering, comprising
a third image forming element consisting of at least contours of the first and second image, the contours comprising a phosphorous material;
wherein the phosphorous material is transparent to the light having the first and the second light characteristics generated by the at least one light source, is excitable by daylight, and is disposed on or within the covering.
2. An electronic apparatus, comprising the arrangement according to claim 1 .
3. The electronic apparatus according to claim 2 , wherein the electronic apparatus is a portable or handheld mobile radio communication equipment, a mobile radio terminal, a mobile telephone, a pager, a communicator, an electronic organizer, a smartphone, a computer, or a multimedia player.
4. The arrangement according to claim 1 , wherein the at least one light source is adapted to generate light in a first and second spectral range, wherein the first light characteristic is the first spectral range and the second light characteristic is the second spectral range.
5. The arrangement according to claim 1 , wherein the at least one light source is adapted to generate light in at least one spectral range, wherein different frequencies of the spectral range have at least a first and a second intensity, wherein the first light characteristic is the first intensity and the second light characteristic is the second intensity.
6. The arrangement according to claim 1 , comprising a first and a second light source, the first light source being adapted to generate light having the first light characteristic, and the second light source being adapted to generate light having the second light characteristic.
7. The arrangement according to claim 1 , wherein the first image forming element comprises a first optical component for providing light having a first characteristic, and the second image forming element comprises a second optical component for providing light having a second characteristic, which is different from the first characteristic.
8. The arrangement according to claim 7 , wherein the first optical component is at least responsive to the light having the first light characteristic, and the second optical component is at least responsive to the light having the second light characteristic.
9. The arrangement according to claim 1 , wherein the first image forming element is arranged to not be responsive to the light having the second light characteristic, and the second image forming element is arranged to not be responsive to the light having the first light characteristic.
10. The arrangement according to claim 1 , wherein the first image forming element and the second image forming element are arranged to display the first and the second image, respectively, in a single physical area.
11. The arrangement according to claim 10 , wherein the first image forming element and the second image forming element are arranged to display the first and the second images in a non-overlapping fashion.
12. The arrangement according to claim 7 , wherein the first optical component comprises a first light filter and the second optical component comprises a second light filter.
13. The arrangement according to claim 12 , wherein a first light source is adapted to generate planar polar light having a first polarization, the light filter of the first optical component is adapted to transfer planar polar light from the first light source, a second light source is adapted to generate planar polar light having a second polarization, which is different from the first polarization, and the light filter of the second optical component is adapted to transfer planar polar light from the second light source.
14. The arrangement according to claim 1 , wherein each of the first image forming element and the second image forming element comprises a transparent element and a non-transparent portion for forming the first and the second image, respectively.
