Baseplate and a method for manufacturing a baseplate for a field emission display

摘要

The present invention is a baseplate that has a supporting substrate with a primary surface upon which an array of emitters is formed. An insulator layer with a plurality of cavities aligned with respective emitters is disposed on the primary surface, and an extraction grid with a plurality of cavity openings aligned with respective emitters is deposited on the insulator layer. The extraction grid is made from a silicon based layer of material. A current control substrate formed from the silicon based layer of material of the extraction grid is provided such that the current control substrate is electrically isolated from the extraction grid and electrically connected to the emitters. The current control substrate has sufficient resistivity to limit the current from the emitters.
