Abstract: |
The invention relates to a filed emission display device, comprising: anode with fluorescent layer, conductive cathode and grid, where the cathode comprises electron emission material, and for a pixel, the electron emission material is distributed on two sides of the grid of the pixel, and the grid is suspended in air between the electronic emission material and fluorescent layer of the pixel. And the preferred: the grid is made of metal wire, which can be gold wire, nickel wire, or other metal wire. And it also comprises at least two insulating barriers and the metal wire hangs on the top of the insulating barriers. And the preferred: the cathode is made of cylindrical metal wire; the electron emission material comprises carbon nano tube, formed on the surface of the cylindrical metal wire. And it has the following advantages: low starting voltage, realizing high-resolution flat display, and improving electron emission efficiency. |
