Abstract:
A double-sided fiber-based display includes a plasma tube array sandwiched between two electro-optic materials. The electro-optic materials are preferably sandwiched between two fiber arrays. The two fiber arrays contain wire electrodes to set the charge in the plasma tubes and are parallel to each other and orthogonal to the plasma tube array. The fibers can be alternatively coated with a transparent conductive coating, such as a carbon nanotube film, to spread the voltage across the surface of the fiber. The plasma tubes contain wire electrodes to ignite a plasma along its entire length. The tube surfaces that are in contact with the electro-optic materials are preferably thin and flat. The fiber and plasma tube wire electrodes are preferably directly connected to a circuit board which houses electronics to address the display.
Abstract:
The disclosure teaches using at least two orthogonal arrays of complicated shaped glass rods or very large fibers-like structures (from here in referred to as fibers) with wire electrodes to fabricate plasma displays with plasma cells larger than 0.05 mm3 in volume. (The volume of a plasma cell is defined by the width of the plasma channel times the height of the plasma channel times the pitch of the pair of sustain electrodes.) To increase the size of the bottom fiber and keep the addressing voltage constant or to reduce the addressing voltage, the address electrode is moved from the bottom of the channel up into the barrier rib. Moving the address electrode up into the barrier rib will reduce the distance, d, between the address electrode and the sustain electrodes, thus increasing the electric field of the addressing pulse. To maintain a more uniform addressing field and build redundancy into the display an additional address electrode can be included in the barrier rib wall on the other side of the plasma channel.
Abstract:
A process for fabricating a fiber-based display includes drawing fiber onto a cylindrical drum, removing the fibers from the drum to form an array of fibers, and laying at least one array of fibers removed from the drum between two plates to form a fiber-based display panel. 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, and field emissive displays.
Abstract:
An array of complex shaped top fibers that each include an address electrode, barrier ribs to form a plasma channel and a phosphor coating on the plasma channel create structure in a plasma display panel. The top fiber array is disposed on the plate facing the viewer and the light generated by the phosphors must penetrate through the top fibers to the viewer. The top fibers can be composed of a colored material associated with the color phosphor layer to add color purity and contrast to the plasma panel. The sustain electrodes are placed on the plate facing away from the viewer and can be included in an array of fibers containing wire sustain electrodes. The sustain electrode surface does not need to be transmissive since the generated light is transmitted through the top fiber array. Therefore, the sustain electrodes can be composed of a reflective metal and cover the majority of the surface of the bottom plate. Covering a large percentage of the bottom plate with sustain electrodes causes the maximum spreading of the electric field and generates the highest plasma efficiency. The sustain electrode bottom plate or array can also be reflective to reflect both the UV light generated by the plasma back toward the phosphor layer and the visible light generated by the phosphor layer back toward the viewer.
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.
Abstract:
The invention relates to a field emission display constructed using an array of fibers and an orthogonal array of emitter electrodes. Each fiber in the fiber array contains an extraction electrode, spacer, a high voltage electrode and a phosphor layer. The array of emitter electrodes consists of carbon nanotube emitters attached to conductive electrodes. The emitter electrodes are separated using non-conductive fibers. A getter material in the form of a wire is placed within the array of emitter electrodes to maintain a high vacuum within the display.
Abstract:
A fiber-based PALC (plasma addressed liquid crystal) display device includes two plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top array includes three alternating top fibers, each top fiber including at least one wire address electrode and built in liquid crystal spacers. The top fibers are composed of a colored material with absorbing sides, which builds into the display the color filter and black matrix functions. The bottom array includes identical bottom fibers, each bottom fiber including a hollow plasma channel and two wire channel electrodes. Polarizing films and liquid crystal alignment layers are applied to the top and bottom fibers, which are assembled orthogonal to each other and a liquid crystal material is filled between them. The PALC display is sealed around the perimeter to contain the liquid crystal and the wire electrodes are brought out through the seal and connected to the drive control system.
Abstract:
A full color fiber plasma display device includes two glass plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top fiber array includes identical top fibers, each top fiber including two sustain electrodes located near a surface of the top fiber on a side facing away from the viewer. A thin dielectric layer separates the sustain electrodes from the plasma channel formed by a bottom fiber array. The bottom fiber array includes three alternating bottom fibers, each bottom fiber including a pair of barrier ribs that define the plasma channel, an address electrode located near a surface of the plasma channel, and a phosphor layer coating on the surface of the plasma channel, wherein a luminescent color of the phosphor coating in each of the three alternating bottom fibers represents a subpixel color of the plasma display. Each subpixel is formed by a crossing of one top fiber and one corresponding bottom fiber. The plasma display is hermetically sealed with a glass frit. The sustain and address electrodes are brought out through the glass frit for direct connection to a drive control system.

Abstract:
A process for frit-sealing together a panel of a fiber-based information display includes assembling the panel and sealing, after the step of assembling, the panel by forcing a glass frit to flow between the two glass plates that comprise the panel using narrow strips of glass. The glass frit-seals the top and bottom glass plates together and covers the wire electrodes at the end of the fibers to dielectrically isolate them from each other. The process of assembling and frit-sealing the panel is particularly suitable for use in an information display, such as plasma emissive displays, plasma addressed liquid crystal displays, and field emissive displays
