Isolation busbar for a flat panel display device

摘要

In a display device having an evacuated envelope, an electron beam guide and an electron generating means for generating beams of electrons, a modulator structure on which is disposed a plurality of control electrodes may be formed by interconnecting selected ones of the control electrodes which operate at a common potential. This interconnected electrode structure decreases the number of control electrodes which extend from the evacuated envelope. The electron generating means is shielded from the interconnected electrode structure to prevent perturbation of the generated electron beams.
