摘要： A liquid crystal display device includes cell wall structure and a chiral nematic liquid crystal material. The cell wall structure and the liquid crystal cooperate to form focal conic and twisted planar textures that are stable in the absence of a field. A device applies an electric field to the liquid crystal for transforming at least a portion of the material to at least one of the focal conic and twisted planar textures. The liquid crystal material has a pitch length effective to reflect radiation having a wavelength in both the visible and the infrared ranges of the electromagnetic spectrum at intensity that is sufficient for viewing by an observer. One liquid crystal material may be disposed in a single region or two or more liquid crystal materials may be used, each in separate regions even without the infrared reflecting layer. One aspect of the invention is directed to a photolithography method for patterning a substrate of the display. The display may also have multicolor capabilities by including separate layers of at least two or three liquid crystal materials that reflect visible light. A full color stacked display may be produced with grey scale capabilities.

摘要： A structure. The structure includes a substrate and an interposer. The substrate includes a heat source and N continuous substrate channels on a first side of the substrate (N≧2). The interposer includes N continuous interposer channels coupled to the N substrate channels to form M continuous loops (1≦M≦N). Each loop independently consists of K substrate channels and K interposer channels in an alternating sequence. For each loop, K is at least 1 and is subject to an upper limit consistent with a constraint of the M loops collectively consisting of the N interposer channels and the N substrate channels. Each loop is independently open ended or closed. The first side of the substrate is connected to the interposer. The interposer is adapted to be thermally coupled to a heat sink such that the interposer is interposed between the substrate and the heat sink.

摘要： In a liquid crystal display device, a method for creating desirable pretilt angle by means of topography of the substrates, such as a surface that is sloped with respect to the surface of the electrodes. In combination with a low pretilt but highly photo-stable alignment layer, which may be very resistant to high levels of ultraviolet radiation, a high pretilt and photo-stable alignment structure is generated, by essentially combining two incompatible technical approaches. The ever more stringent requirements for projection displays are met. The methods for producing such sloped surfaces and the considerations related to design of the sloped surfaces are disclosed.
