A double gate structure ZnO Field Emission Display (ZnO-FED) is proposed. In this kind of structure, a planar gate electrode is printed onto the cathode plate, it is used to modulate the conductive current from the ZnO emitters; a mesh grid with MgO layer is placed above the cathode plate and as the other gate electrode. Compare to the normal planar triode structure ZnO-FED, the focus performance...
A new field-emission triode with a carbon nanotube (CNT) cathode is proposed in this paper. This triode consists of three glass plates: the first one represents the cathode plate, which has an array of holes to which the CNTs are applied by printing; the second plate is mounted below the cathode plate and contains the gate electrodes; and the third one is the anode. The electric field generated by...
Field emission display inherits excellent display qualities of traditional CRT and is a prospective flat display panel. Traditional normal gate FED consists of front and rare glass substrates, using spacer matrix for maintain fixed gap. Compared with diode structure, the modulation voltage is lower in triode structure because of the shorter gap between gate and cathode. However, in a normal gate triode,...
A carbon nanotube field emission display (CNT-FED) composed of a cathode, a gate electrode and an anode is fabricated. The device is analyzed by IR spectra. The gate electrode was fabricated using corrosion reaction. The luminance of the triode structure FED is measured
Summary form only given. Recently, the carbon nanotube field emission display has drawn more and more concern. With its excellent image display quality and low fabrication expense, the printable CNT-FED will take the place of cathode ray tube as the major consumer-priced and mass-market display. A normal CNT-FED device is composed of the CNT cathode, the gate electrode, the anode and dielectric insulator...
In this paper, we calculated and compared the performance of three different structures of CNT-FED: a normal triode structure, a double-gate structure, and a structure with insulator channel. By calculating the electrical field and the electron trajectories, we found that the normal triode structure is easy to induce pixel-pixel interference; while the double-gate structure subtract the anode current...
