Abstract
This invention relates to a display device, a method, a computer program and a system including a display device, wherein said display device includes at least one light transmissive area configured to be coupled to a light source in order to be provided with backlight, at least one light reflective area, at least one light transmission control element associated with said at least one light reflective area, wherein said display device is configured to be switched into a reflective blocking state when said at least one light transmissive area is provided with backlight, and wherein in said reflective blocking state said at least one light transmission control element causes light-blocking.
Claims28
A device, comprising:
- at least one light transmissive area configured to be coupled to a light source in order to be provided with backlight;
- and
- at least one light reflective area and at least one light transmission control element associated with said at least one light reflective area,
- wherein the at least one light transmission control element is separate from the at least one light reflective area and is located above the at least one light reflective area,
- wherein said device is configured to be switched into a reflective blocking state in response to said at least one light transmissive area being provided with backlight, and
- wherein in said reflective blocking state said at least one light transmission control element causes light to be prevented from reaching the at least one light reflective area in response to said at least one light transmissive area being provided with backlight.
A method, comprising:
- determining whether a reflective blocking state of a device is to be entered,
- wherein said device comprises at least one light transmissive area configured to be coupled to a light source in order to be provided with backlight and at least one light reflective area and at least one light transmission control element associated with said at least one light reflective area;
- wherein the at least one light transmission control element is separate from the at least one light reflective area and is located above the at least one light reflective area,
- wherein said reflective blocking state is entered in response to said at least one light transmissive area being provided with backlight, and
- wherein in said reflective blocking state said at least one light transmission control element causes light to be prevented from reaching the at least one light reflective area in response to said at least one light transmissive area being provided with backlight, and in case it is determined that said reflective blocking state is to be entered, switching said reflective blocking state active.
A non-transitory computer-readable medium having a computer program stored thereon, the computer program comprising instructions configured to cause a device to:
- determine whether a reflective blocking state of a device is to be entered, wherein said device comprises at least one light transmissive area configured to be coupled to a light source in order to be provided with backlight and at least one light reflective area and at least one light transmission control element associated with said at least one light reflective area;
- wherein the at least one light transmission control element is separate from the at least one light reflective area and is located above the at least one light reflective area,
- wherein said computer program is configured to cause the device to enter the reflective blocking state in response to said at least one light transmissive area being provided with backlight, and
- wherein in said reflective blocking state said at least one light transmission control element causes light to be prevented from reaching the at least one light reflective area in response to said at least one light transmissive area being provided with backlight, and in case it is determined that said reflective blocking state is to be entered, switching said reflective blocking state active.
