Abstract

A flat tube display apparatus wherein a row of many electron beam generators (2) is arranged transversely in a thin flat vacuum tube body (1) to generate a number of beams in parallel with each other which travel in parallel with an image screen (6) and to deflect the beams toward the image screen at a predetermined position. The beams are guided without being widely diverged due to the provision of a number of side walls arranged in parallel with each other to confine beams and due to the provision of alternately strong and weak magnetic fields along the side walls. Image brightness can be further increased by a frit-glass-­ laminated structure of a multiplier or microchannel (5).
