Abstract

In a flat panel display device a beam guide assembly includes electron guide meshes, a focus mesh and an acceleration mesh, which are retained in a spaced parallel relationship by insulative posts. Modulation electrodes, within an electron gun section of the display device, are extended toward the guide meshes so that the guide meshes and the modulation electrode partially overlap in a spaced parallel relationship. The focus and acceleration meshes are extended toward the gun section to partially overlap the modulation electrodes in a spaced parallel relationship. Insulative posts are arranged along the extended portions to retain the spaced parallel relationships of the electrodes and the meshes. A cathode support is held by the insulative posts and supports a cathode within the gun section in the desired location and orientation with respect to the guide meshes. A unitized beam guide/electron gun assembly is thus achieved.
