Abstract
A flat type color display apparatus includes a phosphor screen and 15 horizontal line cathodes activated in turn from the top one to the bottom one. An electron beam control means and a beam deflection means are provided. Each horizontal line cathode emits a horizontal sheet-shaped electron beam which is vertically deflected in 16 steps, and is divided into 320 rod-shaped electron beams by 320 vertically oblong slits and individually controlled of its intensity by 320 beam-control electrodes. The rod-shaped electron beams are horizontally deflected each selectively impinging R, G and B vertical phosphor stripes in turn. In the operation circuit, R, G and B video signals are sampled and held in R, G and B parts of 320 sample-hold circuits, and stored at one time in 320 memories for respective colors, and time sharingly applied to the respective beam-control electrodes. A color video image is thereby displayed of 240 lines each having 320 picture elements.
