The principle of field-emission display is almost the same as the traditional cathode ray tube, so it should display the image with the same quality as CRT. However, the triode structure and uniformity of field-emission is two key issues regarding the field-emission display. In this paper, a planar triode is discussed deeply. The structure of this planar triode is quite simple, and it can be fabricated...
Printable carbon nanotubes field emission displays with shadow mask (Shadow Mask CNT-FED) is suggested. A layer of insulator is screen printed on the upper surface of shadow mask, and address electrodes are fabricated on it. MgO film is deposited on shadow mask by electron beam evaporation. Secondary emission electrons escape from MgO film under the bombardment of primary electrons. In the simulation,...
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,...
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...
