Abstract

Display apparatuses (100;200;400;500;1400) are shown capable of displaying information in a reflective mode using only ambient light (110;210;510) and in a transmissive mode using a light source (105;205;505;1405). In one embodiment, the display apparatus (100;1400) includes a reflecting polarizer (104;1408) disposed between a light modulating layer (102;1402) and an isotropic light cavity (105,106;1405,1406). The light cavity (105;106;1405;1406) reflects incident light with a first degree of depolarization. The reflecting polarizer (104;1408) reflects light with a second degree of depolarization for at least one polarization that is greater than the first degree of depolarization. In another embodiment of the display apparatus (200;1400), a microstructured film (204;1404) is included above a light cavity (205,206;1405,1406) and below a light modulating system (201,202,203,208,1401,1402,1403,1415) where the microstructured film (204;1404) includes sawtooth formations (207;1407) having at least a tilted surface (211,212;1411,1412). In another embodiment of a dual-mode display device (500), the display (500) includes a cholesteric reflecting polarizer (504) disposed between a light modulating layer (502) and a light cavity (505,506) where the light cavity (505,506) causes a polarization phase shift upon reflectance.
