Abstract: A substrate for a multi-color liquid crystal display (LCD), an LCD having the substrate, and methods of manufacturing the substrate and the LCD. In one embodiment, the substrate includes: (1) a substantially planar base and (2) a cell wall structure, located on a surface of the base, that defines at least first and second sets of independent cells having corresponding independent fluid fill ports when the cell wall structure is bonded to an opposing substrate.

Abstract: A stereographic liquid crystal display (LCD) and various methods of manufacturing and operating such stereographic LCD. In one embodiment, the LCD includes: (1) first and second substrates having a cell wall structure located in an interstice therebetween that defines first and second sets of independent cells in the LCD; (2) a first controllable liquid crystal (CLC) material located in the first plurality of independent cells, the first CLC material selectively exhibiting an "on" state and an "off" state and having a first polarity when in the "on" state; and (3) a second CLC material located in the second plurality of independent cells, the second CLC material selectively exhibiting an "on" state and an "off" state and having a second polarity when in the "on" state.

Abstract: Methods of manufacturing a liquid crystal display ("LCD"); specifically, a multi-color LCD, e.g., a red-green-blue ("RGB") LCD. The methods include the steps of: (1) depositing a twist agent on a first substrate, the twist agent becoming an in situ twist agent, (2) bringing a second substrate into proximity with the first substrate to form at least one interstitial region between the second and first substrates, (3) introducing liquid crystal ("LC") having an initial pitch into the at least one interstitial region proximate the in situ twist agent and (4) stimulating the LC and the in situ twist agent to cause the LC and the in situ twist agent to mix in situ, the in situ twist agent changing the initial pitch of the LC.

Abstract: Driver apparatus and methods of driving at least a portion of a cholesteric liquid crystal ("CLC") panel to a state having a given reflectivity. One of the methods includes the steps of: (1) initially driving the portion to a nematic phase, (2) subsequently driving the portion to a cholesteric phase focal-conic state, the cholesteric phase focal-conic state providing a known reference state for subsequent driving of the portion and (3) thereafter driving the portion to the state having the given reflectivity.

Abstract: A light modulating apparatus containing cholesteric liquid crystals capable of indefinite zero field retention of optical images, including full color and complete gray scale capability, is described. This invention is predicated on establishment of zero field multistable liquid crystal domains representing a continuous distribution of states ranging from the highly reflective planar to the light-scattering focal-conic structures. The zero field multistable domain structure stability is achieved by controlling solid surface-liquid crystal boundary interactions to provide essential equalization of the total system energy of each of the domain structures. This is the first time this equalization, and thus zero field multistability, has been achieved without the use of a polymer gel addition to create rigid polydomains in the liquid crystal mix.

Abstract: A cholesteric liquid crystal display ("LCD") and methods of operating and manufacturing the LCD. The LCD includes: (1) a controllable cholesteric liquid crystal (CLC) located between first and second substrates, the controllable CLC selectively exhibiting an "on" state and an "off" state and having a circular polarity of a predetermined handedness when the controllable CLC is in the "on" state and (2) a circular polarizer, located proximate the first substrate and having a circular polarity of a particular handedness, that cooperates with the controllable CLC to increase the difference between the relative brightness of the "on" state and the "off" state, whereby a contrast ratio of the cholesteric LCD is increased.
