A polarization conversation device (PCS) wherein a series of slots are formed in a frame to orient coated glass plates with retarder elements positioned there between. The PCS components are assembled within the frame and cover plates are secured thereto in a fluid-tight manner forming a fluid tight enclosure for receiving an index-matching fluid for homogenizing the temperature at any bright spots.

Polarization conversion system for projection displays resistant to damage from heat and light

An external electronically controlled illumination module utilizing polarizing beam splitters to split the light beam from a projection lamp into two polarization states, selectively altering the state of each polarized light beam to reject a controlled portion of the light where the selectively altered beams are recombined and passed to the projection system optics.

Video projector illumination system using two lamps having complementary beams patterns

An LCD having the liquid crystal in at least a portion of the interpixel region displaced by a spacer material. The spacer material has a low dielectric constant relative to the liquid crystal, thus further impeding the formation of a bend deformation in the liquid crystal in the interpixel region when pixels on opposite sides of the spacer material are operating in the inversion mode. This elimination of the bend deformation in the interpixel region eliminates the reverse tilt disclination.

Elimination of the reverse-tilt in high-density reflective LCDs

A liquid crystal display apparatus includes a first substrate supporting an array of pixel electrodes, defining a display area, and spacer elements having planarized surfaces defining a plane that is parallel to the pixel electrodes and spaced by a distance corresponding to a desired liquid crystal cell gap. Spacers outside of the display area precisely space a covering substrate carrying a transparent counter electrode at the desired cell gap.

Uniform cell-gap spacing in LCD

A process for producing a catalyst structure comprised of nickel, chromium and copper and having a stratified surface material formed as a coherent layer on a substrate, said substrate being a nickel- and chromium-containing alloy, comprising: providing a copper-containing coating on the substrate, said substrate containing at least about 10 weight percent chromium; and heating said coated substrate in a protective atmosphere to a temperature of at least the melting point of copper to form a surface area material which is or is capable of being developed into a stratified surface material and a chromium-rich sublayer.
