摘要： A stereoscopic image display apparatus that is capable of being efficiently aligned using a remotely controlled alignment function and a method of displaying a stereoscopic image using the same are disclosed. The stereoscopic image display apparatus includes a polarizing beam splitter for spatially splitting image light emitted by a projector into at least one transmitted beam and at least one reflected beam based on polarized components, at least one modulator for adjusting the transmitted beam and the reflected beam such that the transmitted beam and the reflected beam have different polarization directions when a left image and a right image are projected by the transmitted beam and the reflected beam, an angle adjustment unit for adjusting the position on a screen on which the transmitted beam is projected in response to a first remote control signal, a remote-control alignment type reflecting member for adjusting the path of the reflected beam in response to a second remote control signal such that the reflected beam overlaps the transmitted beam projected on the position on the screen adjusted in response to the first remote control signal in order to form a single image, and a remote controller remotely connected to the angle adjustment unit and the remote-control alignment type reflecting member for transmitting the first remote control signal and the second remote control signal to the angle adjustment unit and the remote-control alignment type reflecting member, respectively.

摘要： A directional display may include a waveguide. The waveguide may include light extraction features arranged to direct light from an array of light sources by total internal reflection to an array of viewing windows and a reflector arranged to direct light from the waveguide by transmission through extraction features of the waveguide to the same array of viewing windows. A further spatially multiplexed display device comprising a spatial light modulator and parallax element is arranged to cooperate with the illumination from the waveguide. An efficient and bright autostereoscopic display system with low cross talk and high resolution can be achieved.

摘要： Liquid crystal devices are described that maintain performance of polarization/amplitude modulation under high irradiance conditions. Configurations that isolate polarizing elements under high thermal load are discussed which allow other elements, such as glass, which may be sensitive to stress birefringence to remain near optimum thermal conditions.

摘要： A method of mounting screen material may include a screen mounted to a frame at multiple mounting points. One embodiment may include mounting patches attached along the perimeter of the screen. These mounting patches may be strain relieved in order to enable rolling the screen without sacrificing the in-plane rigidity of the patches when the screen is mounted to a frame. Stated differently, the strain relieved patches may reduce the strain on the screen in the circumstance the screen is rolled onto a core. The mounting patches may be strain relieved by locating notches or slits in the mounting patch.

摘要： A polarization conversion system separates light from an unpolarized image source into a first state of polarization (SOP) and an orthogonal second SOP, and directs the polarized light on first and second light paths. The SOP of light on only one of the light paths is transformed to an orthogonal state such that both light paths have the same SOP. A polarization modulator temporally modulates the light on the first and second light paths to first and second output states of polarization. First and second projection lenses direct light on the first and second light paths toward a projection screen to form substantially overlapping polarization encoded images. The polarization modulator may be located before or after the projection lenses. The polarization-encoded images may be viewed using eyewear with appropriate polarization filters.

摘要： Sistema de conversão de polarização e método para projeção estereoscópica trata-se de um sistema de conversão de polarização que separa luz de uma fonte de imagem não-polarizada em um primeiro estado de polarização (sop) e um segundo sop ortogonal, e direciona a luz polarizada no primeiro e segundo caminhos de luz. O sop de luz sobre apenas um dos caminhos de luz é transformado em um estado ortogonal tal que ambos os caminhos de luz têm o mesmo sop. Um modulador de polarização modula temporariamente a luz no primeiro e no segundo caminho de luz para primeiro e segundo estados de saída de polarização. Primeira e segunda lentes de projeção direcionam luz sobre o primeiro e segundo caminhos de luz na direção de uma tela de projeção par formar imagens codificadas por polarização substancialmente sobrepostas. O modulador de polarização pode estar localizado antes ou após as lentes de projeção. As imagens codificadas por polarização podem ser visualizadas com o uso de óculos com filtros adequados de polarização.

摘要： Disclosed is a light guiding valve apparatus including a light valve a two dimensional light emitting element array and an input side arranged to reduce light reflection for providing large area directional illumination from localized light emitting elements with low cross talk. A waveguide includes a stepped structure in which the steps may include extraction features hidden to guided light propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Stray light falling onto a light input side of the waveguide is at least partially absorbed.

摘要： Described are illumination systems for providing visible images. The systems include a first image projection sub-system operable to provide a first stereo-image output formed by light having a first polarization; a second image projection sub-system operable to provide a second stereo-image output formed by light having a second polarization; a projection means wherein the projection means projects the first and second stereo-image outputs onto a display through a common lens; wherein the system is operable to provide orthogonal first polarization and second polarization. Typically, the first and second image outputs are formed from light having orthogonal polarizations and the system is preferably switchable between providing orthogonal and non-orthogonal first and second images. In preferred embodiments the system is operable to provide nonstereo images while providing increased resolution. Preferred systems include a common light source and a common projection lens. Some systems include digital micromirror devices and liquid crystal on silicon technologies. Related methods of providing visible images are also disclosed.
