Display device comprising fluorescent enhanced reflective holographic illumination |
摘要 |
A display device (10) includes a display panel, such as a liquid crystal panel (12), in combination with a reflective holographic optical element (14) that redirects ambient light for illuminating the display. The light redirected by the holographic element is limited to a predetermined spectral band. Fluorescent film (16) is included for absorbing light outside the spectral band of the holographic element and re-emitting light within the spectral band to increase the light redirected by the holographic element and thus increase the apparent brightness of the display.
