ABSTRACT:
The light output of a color LCD (10) is considerably increased by arranging dichroic mirrors (31, 32, 33) register with the pixels (20), which mirrors pass the color suitable for the pixel and reflect the other colors so that they can be reflected back again by a reflective surface (45) and be used in the display.
