    摘要: An apparatus and system for improving liquid crystal display efficiency by utilizing a polarization sheet. The polarization sheet includes a plurality of prisms capable of separating light source into vertically and horizontally polarized light. A plurality of half wave plates are used to rotate one of the polarized light to create a uniformly polarized light beams. A liquid crystal display (LCD) capable of receiving uniformly polarized light beams. Other embodiments of inventions are described in the claims.
