An adaptive camouflage device that includes at least one non-emissive layer which includes a guest-host liquid crystal (GHLC).

Adaptive camouflage device, system, method and camouflage apparatus

A reflective display device includes a pixel structure () and a liquid crystal () containing a dye. The pixel structure () provides the liquid crystal () with a first tilt state and a second tilt state that are stable absent application of an electric field. In the first tilt state, the liquid crystal () is in an untwisted configuration. In the second tilt state, the liquid crystal () is in a twisted configuration, and the dye has an effective absorption that is higher than an effective absorption of the dye when the liquid crystal () is in the first tilt state.

Liquid crystal display device

A reflective structure with transparent and semi-transparent transmission regions and includes a first transparent layer with a textured area, a reflective layer disposed below the first transparent layer and having a portion that is substantially conformal with at least a first portion of the textured area, and a second transparent layer disposed below the reflective layer and having a portion with a refractive index that is substantially equal to a refractive index of the first transparent layer. The transparent transmission region is configured to transmit a portion of light without substantial deviation, and the semi-transparent transmission region is configured to transmit another portion of the light from the first transparent layer with substantial deviation.

Reflective structure with transparent and semi-transparent transmission regions

A reflective display device includes a first absorption layer configured to be modulated between being strongly and weakly absorbing of light within a first specified wavelength band and to absorb light weakly in a second specified wavelength band and a third specified wavelength band, a second absorption layer configured to be modulated between being strongly and weakly absorbing of light within the second specified wavelength band and to absorb light weakly within the third specified wavelength band, a third absorption layer configured to be modulated between being strongly and weakly absorbing of light within at least the third specified wavelength band, and at least one reflector arranged between two of the first, second, and third absorption layers, the at least one reflector being configured to reflect light strongly within one of the specified wavelength bands assigned to the absorption layers above the at least one reflector.
