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.

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.

An achromatic polarization switch (APS) acts on linear polarized light to provide orthogonal polarized output states over a range of visible wavelengths. In a first switching state, the APS is operable to pass light of a first polarization state therethrough. In a second switching state, the APS is operable to transform light passing therethrough to a substantially orthogonal second polarization state. Used in conjunction with orthogonal analyzing eyewear, left and right eye images are time-sequentially modulated in orthogonal polarization states by the APS to yield a stereoscopic 3D image sensation.

Described is an optical compensator device that can maintain a high degree of performance in the demanding environment of projection display. A mounting process involves using a sealant between optically clear glass or ceramic substrate and low elastic polymer retarder film. The sealant may mitigate or prevent the degradation of the retarder film by acting as an oxygen barrier that seals the substrate and increases the lifetime of the device in high luminance.

A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. The first set of spectral emitters generate a first light bundle and the second set of spectral emitters generate a second light bundle. Several modes of operation may be provided including (1) an advanced 2D mode, (2) an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters, (3) a privacy screen mode, (4) a channel multiplexed mode, and (5) a stereoscopic image mode. The latter three modes utilize the first and second set of spectral emitters to alternately illuminate a portion of the light modulating panel. Images and representations generated by the direct view display operating in the latter three modes are viewed using appropriate eyewear having filters with passband characteristics to transmit the respective light bundle.

Power delivery systems and methods for delivering power from a vehicle to a vehicle door. The system includes a supporting device having a first portion fixedly mounted to a main frame and a second portion attached to a door. The second portion being movable about a hinge axis portion that connects the first portion to the second portion. An energy transmitting source is connected to a power frequency generator. The power frequency generator is connected to a power source and configured to couple an oscillating signal to the energy transmitting source. The energy transmitting source is mounted on the hinge axis portion of the supporting device. An energy receiving device is magnetically coupled to the energy transmitting source to receive a power signal from the energy transmitting source. The energy receiving device is mounted on the second portion of the supporting device at a fixed distance from the energy transmitting source. The energy receiving device receives the power signal from the energy transmitting source to deliver the power signal to powered components associated with the door. The power delivery is uninterrupted during opening and closing of the door.
