Problems solved by technology

In the current flat-panel devices, the structure in which the gate is located above the carbon nanotube cathode is generally adopted. The manufacturing process is relatively simple, and the control function of the gate is relatively significant, but the formed gate current is relatively large. The requirements are relatively high, which is its disadvantage

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 inner concave formed structures of grid control 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 reduces working voltage of grid electrode further, enhances control function and control efficiency of grid electrode so as to be in favor of raising brightness and image quality displayed by the whole apparatus. Advantages are: stable and reliable manufacturing procedure, simple technique and structure, and low cost.
