A colour display unit (1) for a portable communication device, comprising:
an essentially transparent display layer (2) having a front side (2a) provided for displaying information, and a rear side (2b),
a lighting system (3) for illuminating said essentially transparent display layer (2) from the rear side or the front side, said lighting system (3) comprising a light source providing blue light, wherein red and green luminescent material (4a, b) is provided on said display layer (2) on some parts thereof, to provide red and green light when optically pumped with the blue light and in that other parts (4a) of the display layer (2) are essentially transparent, such that the blue light can be transmitted therethrough without passing the red and green luminescent material (4a, b). In this way a brilliant display with saturated colours and high luminance, and a display that in strong sunlight is still possible to be read is provided. |
