<p>A liquid crystal display assembly and method with enhanced brightness is disclosed. The assembly includes a liquid crystal display, a linear polarizing layer extending across the rear surface of the display and an illumination source spaced from the polarizing layer. A brightness enhancing layer disposed between the polarizing layer and the illumination source has a preferred polarization axis, transmitting more light polarized in one direction than another. The brightness increasing layer is oriented with the preferred polarization axis substantially aligned with the transmission axis of the polarizing layer. The method includes the steps of providing a liquid crystal display, positioning a linear polarizing layer proximate the rear surface of the display and illuminating the display with a light source spaced from the polarizing layer. A prismatic film which has a preferred polarization axis and transmits a partially polarized output is positioned between the polarizing layer and the light source. The method further includes the step of orienting the prismatic film with the preferred polarization axis substantially aligned with the transmission axis of the polarizing layer.</p> |
