  • Publication number: 20040012733
    Abstract: A method of manufacturing a liquid crystal display device is disclosed. The method comprises filling the space between two facing substrates with a mixture of pre-polymer and liquid crystal material, applying an external source of energy to initiate a polymerization, wherein as the polymerization proceeds a phase separation of the polymer and liquid crystal is generally also proceeding, after initiation of polymerization and before completion thereof, adjusting a parameter that affects one or both of the rates of polymerization and phase separation, so as to produce a variation in the polymerized structure, wherein the variation is a result of the rates of polymerization and phase separation being adjusted during the course of polymerization.

  • Patent number: 6402039
    Abstract: A chip card including a flexible body; at least one semiconductor chip supported within the flexible body and comprising a memory for storing the information; a display element capable of displaying at least a portion of the information stored in the semiconductor chip, the display element being supported within the flexible body and comprising display areas viewable from at least one side of the chip card; circuitry for controlling the display element; the chip card being capable of undergoing flexing of the type and magnitude experienced by a card during normal use, handling, and storage (e.g., storage in a pocket, wallet, or purse) without permanent damage to the display element and without permanent loss of the displayed information. A chip card may include a power source to provide multi-media capabilities by driving a speaker/microphone or showing a series of images to produce an animated display or film clip.

  • Patent number: 6068183
    Abstract: A method of delivering advertisement information from a source of advertisement information to a chip card for display on a display element of the chip card. The method includes establishing a communication path between the source and the chip card, transmitting the advertisement information from the source to the chip card via the communication path; and, displaying the transmitted advertisement information on the chip card display element. Also featured is a method of electronic ticketing that transmits ticketing information to chip card memory, and displays the ticketing information on the chip card display element.
