Abstract: A field emission display with improved viewing characteristics is described. The field emission display is formed with a baseplate and an opposing face plate. Field emission microtips are formed in openings in a conductive and insulating layer on the baseplate. An anode is formed on either the faceplate, or on the conductive layer surrounding each opening. Phosphorescent material is formed over the anode. A blocking layer is formed between the phosphor and the faceplate, such that during operation of the display direct light emission from the phosphor is blocked, resulting in indirect phosphorescence and a more comfortable display image. An optional reflective layer may be added over the conductive layer to increase phosphorescence.

Abstract: In accordance with the invention, a microwave vacuum tube device, such as a traveling wave tube, is provided with an electron source comprising activated ultrafine diamonds. Applicants have discovered that ultrafine diamonds (5-1,000 nm diameter), when activated by heat treatment in a hydrogen plasma, become excellent room-temperature electron emitters capable of producing electron emission current density of at least 10 mA/cm.sup.2 at low electric fields of 10 V/micrometer. Sources using these diamonds provide electrons for microwave vacuum tubes at low voltage, low operating temperature and with fast turn-on characteristics. A multiple grid structure is described for providing high quality electron beams particularly useful for traveling wave tubes.

Abstract: To fabricate a field emission device a micromechanically manufactured array (1) of widely-spaced tips (2) and a micromechanically manufactured perforated extracting electrode (3) are provided. The outer sides of the perforated extracting electrode are bonded to the array in a way that the perforated extracting electrode is facing the array. With the array of widely-spaced tips and the perforated extracting electrode being fabricated separately and bonded together subsequently, both the number of process steps required for each of the two parts and the manufacturing process costs are reduced.

Abstract: An optical correction layer for a light emitting apparatus having gaps in brightness at the light-emitting surface. The optical correction layer includes a plurality of optical correction regions centered over the gaps, and a plurality of optically transparent regions which overlay the remainder of the light-emitting surface. The optical correction regions include appropriately formed grooves which collect and redirect light adjacent the gap. The light is redirected to cover and effectively conceal the gap. The optically transparent regions permit light to travel through, without redirection.

Abstract: The present invention provides improved methods for making field emission devices by which one can pre-deposit and bond the diamond particles or islands on a flexible metal foil at a desirably high temperature (e.g., near 900.degree. C. or higher), and then subsequently attach the high-quality- emitter-coated conductor foil onto the glass substrate. In addition to maximizing the field emitter properties, these methods provide high-speed, low-cost manufacturing. Since the field emitters can be pre-deposited on the metal foil in the form of long continuous sheet wound as a roll, the cathode assembly can be made by a high-speed, automated bonding process without having to subject each of the emitter-coated glass substrates to plasma heat treatment in a vacuum chamber.

Abstract: A field emission display with focus mesh, and the method of making such a display, is described. There is a glass substrate acting as a face for a faceplate of the display. A conductive layer is formed over the glass substrate. A focus mesh dielectric that is formed over the conductive layer comprises a pattern of intersecting lines formed perpendicularly to one another. A focus mesh conductor overlays the focus mesh dielectric. Phosphor elements are formed within and separated from the pattern of intersecting lines, and over the conductive layer. During operation of the display, a first voltage is applied to the conductive layer, and a second voltage is applied to the focus mesh conductor. The first and second voltages create an electric field that focuses electrons emitted from field emission microtips, located at the baseplate, on to the phosphor elements.
