摘要： A pulsed laser device and a laser display system using the pulsed laser device are disclosed that thwart recording of displayed video images with electronic imaging devices. The pulsed laser device is Q-switched, whereby the Q-switch trigger pulses have a temporal pattern that includes a blanking period of a duration that is longer than a repetition time between consecutive trigger pulses and shorter than a time period perceived by the human eye. The output beam of the Q-switched pulse laser is frequency-converted by non-linear optical frequency conversion into an imaging beam, for example, a three-color RBG beam, that can be modulated for displaying color images. The blanking period renders the displayed images practically unsuitable for off-screen recording with electronic image recording devices, such as CCD movie cameras.

摘要： A flat panel display includes a backlight with a plurality of lasing elements. A light distributor distributes light from the lasing elements across the flat panel display. In edge-lit backlights, the light distributor may be a light guide. In direct-lit backlights, the light distributor may be one or more light diffusers that randomize the polarization of light. A polarization enhancement film increases the polarization of light from the light distributor by allowing light of a first polarization to pass through the film and reflecting light that is not of the first polarization back into the backlight. The light reflected back into the backlight is randomly re-polarized within the backlight. An array of light modulators arranged across the flat panel display modulates light emitted by the backlight.

摘要： Methods and systems are described herein which produce polarization-independent full color images suitable for rear-projection television sets and other multimedia displays. The system uses illumination with R, G, B light from two different light sources for each color. A viewer wears glasses with narrowband optical filters, preferably holographic filters. The R, G, B light from the light sources is slightly offset at each of the 3 emission wavelengths, with one set of R, G, B light being filtered by the holographic filter in front of the left eye of the, and the other set of R, G, B light being filtered by the holographic filter in front of the viewer's right eye.
