    摘要: A method and apparatus that reduces laser speckle by using stimulated Raman scattering in an optical fiber. The pulse repetition frequency of the laser is adjusted to control aspects of the laser light such as color or despeckling. In DLP projection systems, an optical monitor may be used to send information to a bit sequence, and the bit sequence may control the pulse repetition frequency of the laser based on the optical monitor signal.

    摘要: A projection system that includes a projector that projects light in wavelength bands, including a non-laser light source and a screen that includes at least two metal layers separated by a layer of dielectric material. The screen is constructed and arranged to reflect light in the wavelength bands projected by the projector and to not reflect light not in the wavelength bands.

    摘要: A bezel-less video display that includes a liquid-crystal display panel, a sheet in front of the liquid-crystal display panel, and an optically transparent material which fills the volume between the display panel and the sheet. The sheet has an antiglare coating which has a gloss level less than 50 gloss units at 60 degrees angle of incidence. The antiglare coating also has a transmissive resolution of at least 10 cycles/mm.
