    摘要: An optical system utilizing a unique polarizer separating plate to replace conventional PBS prism is disclosed. The optical system of this invention, which may be applied to projection display apparatuses such as rear projection type televisions, includes an illumination system for generating a homogeneous light beam, a polarizer separating plate comprising a polarization separation surface that splits the light beam into a first polarized light beam with a first polarization status and a second polarized light beam with a second polarization status, wherein the first polarized light beam propagates through a first aberration compensation lens to a first panel, and a second polarized light beam propagates through a second aberration compensation lens to a second panel. According to one embodiment, the polarizer separating plate includes two sheets of glass substrates having the same thickness and the polarization separation surface is sandwiched by the two sheets of glass substrates.

    摘要: An illumination system suited for projection display applications is disclosed. The illumination system according to this invention includes a red light-emitting diode (R-LED) light source array, a green light-emitting diode (G-LED) light source array, and a blue light-emitting diode (B-LED) light source array. In one preferred embodiment, the R/G/B-LED light source arrays are coupled to different sides of an x-cube component. Light beams emanated from respective light source arrays are combined by the x-cube component, thereby generating a white-light source for display purposes.

    摘要: This invention provides a polarization conversion light pipe device suited for LCD- or LCoS-based projection applications. The polarization conversion light pipe device encompasses a light tunnel defined by four side reflection mirrors with a rectangular cross section. The light tunnel has a light entrance face at one end and a light exit face at the other end. A front reflection mirror having an aperture thereon is mounted on the light entrance face. A retardation plate for rotating the direction of an electric field of a polarized light beam is situated in the light tunnel. A polarization beam splitter module is situated between the exit face of the light tunnel and the retardation plate. The polarization beam splitter module has a reflective polarization beam splitting surface that is substantially 45 degree-inclined with respect to one of the side reflection mirrors.
