Problems solved by technology

At present, in most display devices, the gate structure is used above the carbon nanotube cathode. The manufacturing process of this control form is relatively simple, and the control effect of the gate structure is significant, but the gate current formed Relatively large, greatly reducing the display brightness of the overall display device

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 side grid control structure of beveled cathode 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 enhances control function of grid structure greatly, increases emission area and emission efficiency of cathode of Nano carbon tubes so as to be in favor of raising display brightness of whole apparatus further. Advantages are: stable and reliable manufacturing procedure, simple technique and structure, and low cost.
