Abstract:
A reflective display is formed using two orthogonal fiber arrays and an electro-optic material. The bottom fibers contain plasma channels, used to address the electro-optic material. Wire electrodes built into the fibers address both the plasma and the electro-optic material. The fibers are composed of glass, plastic or a combination of glass and plastic. Color is imparted into the display using colored fibers, adding a color coating to the surface of the fibers, or adding the color to the electro-optic material. The electro-optic material consists of a liquid crystal material, electrophoretic material, bichromal sphere material, electrochromic material, or any electro-optic material that can serve to create a reflective display. Another possible reflective display is formed using an array of hollow tubes filled with an electrophoretic material sandwiched between two plates.
Abstract:
A fiber-based display includes orthogonal arrays of fiber with co-drawn wire electrodes placed between two plates to form an information display. One of the key concepts of the invention is that all structure of each row and column of a display panel is contained within each fiber of both arrays. Therefore, the entire functionality of the display is contained within each fiber of the display. Containing the structure of the display within the fibers not only eliminates multi-level alignment process steps, but allows for the fabrication of very large flat panel displays. The fiber arrays are formed by drawing fiber from a preform onto a cylindrical drum and then removing them from the drum as a sheet of fibers. The fiber arrays are assembled between the plates before a seal is applied. Tight control of the fiber shape and cross-section is obtained using a lost glass or polymer process. The cross-sectional shape of the fibers in the fiber arrays are suitable for use in a flat panel display, such as plasma emissive displays, plasma addressed liquid crystal displays, field emission displays, reflective displays, three-dimensional and multiple view displays.
Abstract:
A process and system for controllable production of continuous lengths of microwire having a core covered by a glass coating are provided. According to the method of the invention, a glass tubing is loaded with a core material. Thereafter, the process includes the step of heating the tubing containing the core material for melting thereof, softening a tip of the glass tubing and forming a drop of the core material in the molten state surrounded by an outer glass shell. During the process, the gas is evacuated from the glass tubing in order to control elevation of the drop. The method includes drawing the heated outer glass shell into a continuous microwire filament and stabilizing the temperature and mass of the drop during the process. Accordingly, the system includes a suitable glass feeder mechanism, a rod feeder mechanism, a furnace configured for forming a drop of the core material in the molten state surrounded by an outer glass shell, controllable vacuum and cooling devices and a receiver section for receiving the microwire obtained after the cooling. The system also includes a controller and sensing means configured for producing signals representative of the gas pressure in the tubing, temperature temperature of the drop, the speed of the microwire, the value of the microwire diameter, the value of the spool diameter and other relevant parameters.
Abstract:
The invention relates to photonic fibers and methods for the production thereof. A photonic fiber consists of a central area and ducts surrounding said central area and is characterized by the fact that at least two metallic conductors (2) are disposed near and along a central fiber (1). A photonic crystal fiber consists of a central fiber core and air ducts surrounding said central fiber core and is characterized in that at least six inner ducts are arranged so as to border the central fiber core while outer ducts are disposed so as to border the inner ducts. According to the inventive method for producing said photonic fibers, capillary elements and/or rods made of glass are combined into geometrical structures comprising at least one central fiber and an outer coating, said geometrical structures are heated and are subjected to a drawing process, and molten liquid metal is filled into hollow spaces of the capillary elements near the central fiber once the drawing process has been completed.

Therefore, the entire functionality of the display is contained within each fiber of the display. Containing the structure of the display within the fibers not only eliminates multi-level alignment process steps, but allows for the fabrication of very large flat panel displays. The fiber arrays (17 or 27) are formed by drawing fiber from a preform onto a cylindrical drum (70) and then removing them from the drum as a sheet of fibers. The fiber arrays are assembled between the plates before a seal is applied. Tight control of the fiber shape and cross-section is obtained using a lost glass or polymer process. The cross-sectional shape of the fibers in the fiber arrays are suitable for use in a flat panel display, such as plasma emissive displays, plasma addressed liquid crystal displays, field emission displays, three-dimensional and multiple view displays.
Abstract:
A drawn glass-coated metallic member has a thermal contraction coefficient differential such that the thermal contraction coefficient of the glass is less than that of the metallic member. The thermal contraction coefficient differential is maintained within a predetermined range during drawing. The glass is placed under residual compression, interfacial bonding between said glass and said wire is substantially uniform, and surface cracking and bond breaks between metal and glass are substantially prevented. A dynamic balance is maintained between the surface tension of the molten alloy and the resistance to high temperature deformation by the glass vessel in which it is contained, enabling the production of glass-coated amorphous or nanocrystalline alloy members having predefined cross-sectional shapes.
