<p>A radiant energy conservation LCD display (100) includes a cavity (108) having a highly reflective, diffusing interior surface (107). A back light (110) is mounted within the cavity (108). A filter (104, 106) is located forward of the back light (110) for transmitting filtered light (116) of specified frequencies and for reflecting out of band light (114) rather than absorbing it. The filter (104, 106) includes a reflecting polarizer (106) for transmitting a light (112) having a first polarization (116) and reflecting a light having a second polarization (114).</p> |
