Display device and use thereof
First Claim
1. A display device comprising:
- at least one display area provided with a plurality of pixels;
for said at least one display area there is provided;
at least one sensor for detecting a property of light emitted from the said at least one display area into a viewing angle of the display device, said sensor being located outside or at least partially outside the viewing angle;
an at least partially transparent optical coupling device located in a front section of said display device and comprising a light guide member for guiding at least one part of the light emitted from the said display area to the corresponding sensor; and
wherein said at least partially transparent optical coupling device further comprises an incoupling member for coupling the light into the light guide member.

Abstract
The display device has a sensor system with at least one sensor for detecting the intensity or color of light emitted from at least one display area of the display device into the viewing angle of the display device. The sensor system further has in one embodiment an at least partially transparent sensor. The sensor system has in another embodiment at least one optical coupling device including a light guide member and a incoupling member for guiding or directing, e.g. deflecting, reflecting, bending, scattering, diffracting, at least one part of the light emitted from the display area to the corresponding sensor, where the sensor is located outside or at least partially outside the viewing angle of the display device.

15. A method of display using a display device comprising at least one display area provided with a plurality of pixels,
comprising the steps of: -
providing for said at least one display area;
at least one sensor for detecting a property of light emitted from said display area into a viewing angle of the display device;locating said sensor being located outside or at least partially outside the viewing angle of the display device; coupling by an at least partially transparent optical coupling device located in a front section of said display device, at least one part of the light emitted from the said at least one display area to the corresponding sensor, and guiding said at least one part of the light emitted from the said display area to the corresponding sensor via a light guide member; and sensing a light property in at least one display area, wherein said at least partially transparent optical coupling device further comprising an incoupling member for coupling the light into the light guide member. - View Dependent Claims (16, 17, 18, 19)
