Abstract

The flat panel display includes cathode glass faceplate, anode glass faceplate, and sealed vacuum cavity surrounded by glass frame. There are control grid electrodes, Nano carbon tubes, and structures of branch type grid control cathode array 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 effective electron emitting area of Nano carbon tubes and reduces working voltage of grid electrode further so as to raise image quality displayed by the integral apparatus. Advantages are: stable and reliable manufacturing procedure, simple technique and structure, and low cost.
