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.
Claims34
A field emissive display, comprising:
- a) at least one electron emission electrode controlled by at least one orthogonal extraction electrode;
- b) at least one fiber containing at least one high voltage electrode and at least one phosphor emissive layer;
- and
- c) at least one spacer fiber used to support the structure of said field emissive display under high vacuum.
A method of creating a uniform specific gap between fibers in an electronic display comprising;
- a) adding a material between said fibers to maintain a specific gap between said fiber;
- b) holding said fibers rigidly in place;
- and
- c) removing said material between said fibers.
A method of fabricating fiber for an electronic display comprising:
- a) drawing fiber from a preform;
- b) placing shape holding tool into the draw region to hold the shape of said preform/fiber during the draw process.
A method of fabricating fiber for field emission display where a sacrificial part of the fiber is used to hold the shape of the fiber during the fiber draw process an is subsequently removed using one of the follow processes:
- a) chemically removed using a lost glass process;
- b) mechanically removed using a reaming tool;
- c) mechanically removed using a sacrificial wire and tearing said wire from said fiber.
