Abstract: A light emitting device has an enclosure with a face portion, a cold cathode within the enclosure, a phosphor layer disposed on an interior surface of the face portion, an extracting grid between the cold cathode and the phosphor layer and a defocusing grid between the extracting grid and the phosphor layer. Electrons emitted from the cold cathode are defocused by the defocusing grid and impact the phosphor layer when an electric field is created between the cold cathode and the phosphor layer due to applied voltages at the cold cathode, extracting grid, defocusing grid and phosphor layer. The phosphor layer emits light through the face portion in response to electrons incident thereon. Secondary electron emission may also occur resulting in increased electron impact upon the phosphor layer, thereby increasing light output. A mirror layer may be included to reflect light toward the face portion of the light emitting device. The mirror layer also inhibits low energy electrons from impacting the phosphor, thereby enhancing the blink rate of the light emitting device.

Abstract: A masking layer is provided on selected areas of an electrode structure that is at least partly performed, to define masked areas and unmasked areas (emitter cells). A first constituent with particles and a second constituent are then applied to the emitter cells, and the particles are selectively directed towards the bottoms of the emitter cellsnulle.g. by electrophoresis. The masking layer is then removed from the masked areas, together with any stray quantities of the first and second constituents on the masking layer. The first and second constituents are then processed (e.g. by curing) to create broad area field electron emission sites in desired locations of the electrode structure.

Abstract: Provided are a low-temperature formation method for emitter tips including copper oxide nanowires or copper nanowires and a display device or a light source manufactured using the same. The low-temperature formation method includes preparing a substrate having an exposed copper surface. The copper surface contacts an oxide solution at a low temperature of 100null C. or less to grow copper oxide nanowires on the surface of the substrate. Optionally, a reduction gas or a heat is supplied to the copper oxide nanowires, or plasma processing is performed on the copper oxide nanowires, thereby reducing the copper oxide nanowires to copper nanowires. Thus, emitter tips including copper oxide nanowires or copper nanowires are formed densely at a low temperature such that the emitter tips have a shape and length suitable for emission of electrons.
