Abstract: A display having electrically activable display medium (16 or 17) positioned between first and second support members (12 and 14 or 72 and 74) each of which carries electrode means (such as 19 or 54) has at least one of said support members (14) comprising a plurality of segments (such as 41-44 or 50 and 52 or 66) with adjacent segments being aligned edge-to-edge. Each segment preferably has a plurality of pixel electrodes (19 or 54) and the display preferably comprises a larger number of pixels.

Abstract: A liquid crystal display comprises (a) a first transparent base; (b) a plurality of first picture electrodes on the first transparent base; (c) a plurality of data lines for supplying electrical signals to the first picture electrodes; (d) a second transparent base, parallel to and spaced apart from the first transparent base; (e) a plurality of second picture electrodes on the second transparent base; (f) a plurality of varistor elements made of a varistor material comprising zinc oxide as a primary metal oxide and cobalt and praseodymium oxides as additive metal oxides, in amounts of between 0.1 and 8.0 atom % cobalt and between 0.08 and 8.0 atom % praseodymium, one varistor element being associated with and in electrical contact each second picture electrode; (g) a plurality of scan lines for supplying electrical signals to the second picture electrodes via the respective associated varistor elements; and (h) electrooptically active liquid crystal material between the first and second picture electrodes. In a preferred embodiment, the plurality of varistor elements is in the form of a varistor array comprising an integral body of varistor material having two major opposing faces, one of the opposing faces having an array of indentations thereon, each indentation defining a varistor element.

Abstract: A liquid crystal projection display, having (a) a light source for producing light of at least two different primary colors; (b) an imaging element corresponding to each primary color light produced by the light source, each imaging element comprising plural pixel elements, each pixel element comprising liquid crystal composition dispersed in plural volumes in a containment medium and being independently addressable to primarily scatter light incident thereon in the absence of a sufficient electric field and to primarily transmit light incident thereon in the presence of a sufficient electric field; and (c) a lens for projecting light transmitted by each imaging element onto a screen; the liquid crystal composition in the pixel elements of the imaging element corresponding to the primary color light of longest wavelength including a pleochroic dye of a color complementary to the primary color light of longest wavelength, which pleochroic dye preferentially absorbs incident light which has not been scattered by the liquid crystal material in the absence of the sufficient electric field and transmits incident light in the presence of the sufficient electric field.

Abstract: A display presenting an image having enhanced contrast has a screen which switches between a bright, image-presenting state and a dark, image-less state, to minimize glare from ambient light reflections. Alternatively, a shutter which switches between a substantially transparent state and a dark, light absorbing state is placed over a conventional screen.
