Flat-board display of round grid side-wall emitting structure and mfg. process

Abstract

The flat panel display includes cathode glass faceplate, anode glass faceplate, and sealed vacuum cavity surrounded by glass frame. There are cathode conductive layer, Nano carbon tubes, and sidewall emission structure of round grid on the cathode glass faceplate. There are anode conductive layer and phosphor layers prepared on the conductive layer on anode glass faceplate. Structure of supporting wall and attached elements of getter are located between anode glass faceplate and cathode glass faceplate. The invention increases electronic field-emission area of cathode of Nano carbon tubes, electronic emission efficiency, and enhances control function of grid electrode so as to be in favor of raising display brightness of apparatus further. Advantages are: stable and reliable manufacturing procedure, simple technique and structure, and low cost.
