18.4: Field Emission Display Architecture based on Hopping Electron Transport

The Hopping Field Emission Display (HopFED) is a new architecture for field emission displays. In this architecture electrons from each sub-pixel are transported in a hopping mode via secondary electron emission over the wall of a funnel placed above the sub-pixel emitters. This leads to the following advantages: Improved sub-pixel electron spot, improved contrast and color purity, reduced damage to field emitters by ion-bombardment and a low capacitance addressing option.
