A new structure of under-gate carbon nanotube (CNT) field emission display (FED)panel is proposed in this paper with normally-on driving scheme. In this structure, the gate electrode is still located beneath the cathode with the cathode and focus electrode arranged alternately. The effect of the under-gate is to prevent the field emission when the negative voltage is applied on the gate electrode...
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...
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...
