Abstract: A transmitting-type liquid crystal display projection system including a planar light source which emits planar white beam or planar R/G/B beams in succession is provided. A first polarization filter receives the planar light source and polarizes the same to be in a first polarization state. A liquid-crystal light valve receives the polarized planar light source, and converts the first polarization state to a second polarization state having a corresponding gray level. A second polarization filter receives a light output from the liquid crystal light valve to produce a second polarization light beam. A projection unit projects the second polarization light beam onto a display plane. Using the same planar light source, a polarization beam splitting (PBS) device with a refection-type liquid crystal light valve can be used to achieve the reflection-type projection system.

Abstract: A polarized light illumination device is described, which includes a light source, a polarizer, a reflector, and a polarized light converter. The light source generates light. The reflector is used for reflecting light generated by the light source towards the polarizer. The polarizer allows a first polarized light to pass through, and reflects a second polarized light. The polarized light converter reflects the light irradiated on the polarized light converter and performs a polarization conversion. A plane where the polarized light converter is located is substantially perpendicular to the polarizer.

Abstract: A light-beam generator and a projecting system having the light-beam generator are proposed in the present invention. The light-beam generator includes an optical element and a light-emitting diode, wherein the optical element further includes a non-spherical reflecting curved surface which at least has a focus. Also, the light-emitting diode is located at the focus of the optical element for emitting light to the reflecting curved surface to form a light beam which is guided in a specific direction. By such arrangement, an output efficiency of light beams can be improved and a heat dissipation requirement can be reduced. Additionally, the light-beam generator proposed in the present invention can be applied to a projecting system having illuminant with specific polarized directions, so as to eliminate various prior-art drawbacks.

Abstract: A polarization converter for unpolarized light. The polarization converter comprises a prism, a wedge, a set of lens arrays, a first reflecting plane, and a second reflecting plane. The wedge comprises a tilt plane. The tilt plane is coated with multi-layer polarization dichronic thin film. The set of lens arrays comprises a light distributor and a light integrator. The tilt plane of the wedge is glued on the first reflecting plane. A second reflecting plane is the unglued plane of the wedge. When a light beam is incident towards the incident plane, the first reflecting plane splits and polarizes the light beam into a first type polarized and a second type polarized lights. Through the multi-layer polarization dichronic thin film, about 99% of the first type polarized light is reflected, and about 99% of the second type polarized light is transmitted and incident on the second reflecting plane. By adjusting the critical angle between the second reflecting plane and the air, almost all the second type polarized light is reflected. The second type polarized light is then traveling through a half-wave plate and converted to a first type polarized light. A good uniformity and a high efficiency are obtained on the projection screen by the disposition of a light distributor lens array in front of the incident plane and a light integrator lens array on the emerging plane of the prism.
