Abstract: This invention relates to a video display device in which the image area of the screen is divided into multiple sectors in the vertical direction and an electron beam is vertically deflected at each of these sectors to display multiple image lines, and particularly to a construction of cathode wires suspended horizontally in order to generate an electron beam at each sector. In this invention, distance between the wire cathodes and back electrode and also between the wire cathodes and the control electrode are held constant by providing insulated members under the wire cathodes.

Abstract: In an image display apparatus, horizontal-extended line cathodes (22a-22d), an electron beam extraction electrode (23), a control electrode (24), a first focusing electrode (25) having horizontal-elongated apertures (35, 45), a second focusing electrode (26) having vertical-elongated apertures (36, 46), a horizontal deflection electrode (27a, 27b), a vertical deflection electrode (28a, 28b) and a screen (29) are provided in this order toward a travelling direction of electron beam, and each of both deflection electrodes comprises a pair of comb-shaped conductive sheets which are insulatedly interdigitated with each other on the same vertical plane.

Abstract: 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.
