Abstract:
A display apparatus is provided to implement high electric field dispersion and uniform electron discharge characteristic by using an NPC(Nano-Porous Carbon) as an electron discharge source. A first substrate(110) and a second substrate(120) are arranged to face each other. At least one cell(150) is formed between the substrates. A first electrode(131) is arranged between the substrates to face the cells. An emitter layer(141) is formed on the first electrode by including an NPC material so as to discharge electrons into the cell by a voltage applied from the first electrode. Gas is filled in the cell to generate ultraviolet rays by electrons which are discharged through the emitter layer. A light emitting layer(125) is formed on a region corresponding to the cell in order to generate luminous energy by reacting to the ultraviolet rays. The emitter layer is formed by pattern-printing NPC paste through an ink-jet printing method.
Abstract:
A method for manufacturing a field emission electrode by using an array of a nano-wire is provided to enhance largely a high field emission effect by using characteristics of the nano-wire. Dispersion is formed by diluting a nano-wire or a nano-wire including magnetic particles in an organic solvent. The dispersion is dispersed into a base fixed to a top end of a magnetic field generation unit. The organic solvent is evaporated from the dispersion of the base so that the nano-wire is aligned at an arbitrary angle in a vertical line or a horizontal line or between the vertical line and the horizontal line along a magnetic field direction in the magnetic field. A metal is deposited on the base in order to fix the aligned nano-wire on the base.
