Abstract:
A display apparatus, comprising:a light modulating layer; a light cavity adapted to provide light to the light modulating layer, the light cavity reflecting of the incident light; and a diffusely reflecting polarizer, disposed between the light modulating layer and the light cavity, for transmitting a component of the light provided by the light cavity having a first polarization for viewing and diffusely reflecting a component of the light, received from the light cavity, having a second polarization, the polarizer diffusely reflecting the light of the second polarization with a second degree of depolarization greater than the first degree of depolarization to provide light of the first polarization; wherein at least a portion of the diffusely reflected light of the first polarization is reflected by the light cavity without depolarization toward the diffusely reflecting polarizer for transmission therethrough.
