Image display apparatus with deformable accelerating electrodes

摘要

An image display apparatus provided with wire electron sources, electron beam control electrodes for controlling the electron beam emitted from the electron sources, electron beam deflecting electrodes for deflecting the electron beam, electron beam accelerating electrodes an electron beam light-emitter which emits light when struck by an electron beam, and an evacuated enclosure having a transparent face at which the light-emitter is positioned and enclosing the electron source and electrodes, at least the electron beam accelerating electrodes being electrodes which are adapted to be deformed when subjected to a Coulomb force to a predetermined beam position, thereby eliminating the adverse effect on the image due to deformation of electrodes cause by the Coulomb force generated when each electrode has a voltage applied thereto.
