In a triode carbon nanotube FED employing barrier ribs, barrier ribs are formed on cathode lines by a screen printing method, a mesh structure is mounted on the barrier ribs, and a spacer is inserted between the barrier ribs through slots of the mesh structure, thereby stably fixing the mesh structure and the spacer within a FED panel due to support by the barrier ribs.
Abstract:
A method for fabricating a field emission device which can display a color image. Anodes to be doped with a color fluorescent film of the same color are connected to each other so that the color fluorescent film can be coated on the anodes of a front surface substrate using an electrophoretic method. An insulating layer is formed between anodes which cross each other to prevent the anodes from contacting each other. It is possible to obtain a cheap and clean fluorescent film by sequentially forming the fluorescent films of the respective colors by the electrophoretic method. The field emission device can be easily packaged since the anodes of the front surface substrate on which the fluorescent film is formed can easily contact the external terminals of the rear surface substrate.
Abstract:
An electric field emission display (FED) and a method for manufacturing a spacer thereof are provided. The FED includes a spacer having a structure in which a multi-focusing electrode layer, an electron beam amplifying layer and a getter layer are stacked between an anode and a cathode, or a spacer having a structure in which a first electrode layer, a first insulating layer, a second electrode layer, a second insulating layer, a third electrode layer, a third insulating layer and a fourth electrode layer are sequentially stacked. Thus, electron beams can be easily focused by the multi-focusing electrode of the spacer, and high luminance can be realized at low current due to electron beam amplification of the electron amplifying apparatus. Also, the diamond tip is used as an electron emission means, to thereby obtain a low driving voltage, stability at a high temperature, and high thermal conductivity. Also, a getter formed of a thin film is used, to thereby minimize a getter adhesion space, and an insulating layer formed of ceramic is used, to thereby suppress leakage current of the electrodes. According to the method for manufacturing the FED and a spacer thereof, time for manufacturing the spacer is reduced, and support stiffness is increased by the insulating layers formed of ceramic interposed between the electrode layers, to thereby increase the aspect ratio of the spacer to a desired level. Also, a multitude of electrode layers to which the negative voltage is applied, is provided in the spacer, to thereby suppress absorption of electrons to the surface of the spacer, and the number of electrons colliding against the fluorescent material is increased, to thereby increase the luminance of the device.
Abstract:
A field emission device by which a color image can be displayed and a method for fabricating the same are provided. The anodes to be doped with the fluorescent film of the same color are connected to each other so that the color fluorescent film can be coated on the anodes of the front surface substrate using the electrophoretic method. The anodes crossing each other are detoured by forming an insulating layer in an area in which the electrodes cross each other. It is possible to obtain a cheap and clean fluorescent film by sequentially forming the fluorescent films of the respective colors by the electrophoretic method. Packaging can be easily performed since the anodes of the front surface substrate on which the fluorescent film is formed can easily contact the external terminals of the rear surface substrate.

A method is provided for fabricating a field emission device which can be adopted as the source for a flat panel display, an ultra-high frequency amplifier sensor, or an electron-beam-applied instrument. A polyimide layer is used as a release layer and a metal mask is formed thereon, thereby enabling the height of micro-tips to be easily controlled. Since the polyimide layer is soluble in an appropriate solvent, contamination does not occur during an etching process, thereby increasing the reliability of the device.
