摘要： Projection systems and methods for providing stereoscopic images viewed through passive polarizing eyewear. The systems relate to projectors that create left and right eye images simultaneously and often as side-by-side images on the image modulator. The systems act to superimpose the spatially separated images on a projection screen with alternate polarization states. The embodiments are best suited to liquid crystal polarization based projection systems and use advanced polarization control.

摘要： A polarization conversion system (PCS) (100) is located in the output light path of a projector (122). The PCS may include a polarizing beam splitter (112), a polarization rotating element (114), a reflecting element (16), and a polarization switch (120). Typically, a projector outputs randomly-polarized light. This light is input to the PCS (100), in which the PCS separates p-polapzed light and s-polarized light (126) at the polarizing beam splitter (112). P-polapzed light (124) is directed toward the polarization switch on a first path. The e-polarized light (126) is passed on a second path through the polarization rotating element (e.g., a half-wave plate) (114), thereby transforming it to p-polarized light (124) A reflecting element directs the transformed polarized light (now p-polarized) (124) along the second path toward the polarization switch (120). The first and second light paths are ultimately directed toward a projection screen (130) to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.

摘要： Described are methods, systems and apparatuses that provide light sources to illuminate an LCD panel for a visual display. A light source includes a light emitting diode (LED) and a spectral filter. The spectral filter is operable to transmit a first set of spectral bands and block a second set of spectral bands from the LED. The spectral filter may be based on retarder stack technology or dichroic filter technology. Polarization and light recirculation techniques are disclosed and implementations into display systems described. These approaches are deemed useful for LED illuminated direct view color encoded stereoscopic systems based on LCD technology.

摘要： Stereoscopic display system assemblies may be configured to have optimal performance with passive, circular analyzing, cinema eyewear. They may comprise non-twisted electrically controlled birefringent liquid crystal modulators oriented at ± 45° to the polarizer orientation of the eyewear. Exemplary embodiments may include single half-wave modulators with a crossing (i.e. negating) quarter wave films. The natural polarization state of the LCD may be rotated and cleaned-up when necessary to cross with the horizontal eyewear polarizer orientation. In an embodiment, the LC modulator substrate is positioned outermost for anti-reflection coating tolerance, durability and touch sensitivity.

摘要： Generally, this disclosure concerns the angle sensitivity of polarization switch elements and the resulting impact of the ray direction on performance. More specifically, apparatus and techniques for compensating the angular sensitivity of liquid crystal (LC) polarization switches are described that enhance the performance of polarization switches. For example, a polarization switch is disclosed that transforms linearly polarized light of an initial polarization orientation that includes a first and second liquid crystal cell with a compensator located between the LC cells. The compensator layer is operable to enhance the field of view through the polarization switch. Such compensation techniques are particularly useful for short-throw projection environments.

摘要： A system for stereoscopic display and a bendable polarization switch for use with a system for stereoscopic display provide alternately polarized left and right eye images. Viewers then wear polarization analyzing eyewear to correctly see the different images. More specifically, a bendable polarization switch may be laminated to the front of a system for stereoscopic display. The bendable polarization switch may be used with a modulator configuration that is compatible with various performance requirements in a manner that is a low-cost manufacturing friendly solution. Further, the bendable polarization switch is a robust polarization switch technology that is reliable in an environment where mechanical stresses are inevitably applied during product lifetime.
