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.

Description

technical field [0001] The invention belongs to the fields of flat panel display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to device fabrication of flat panel field emission displays, in particular to carbon nanotube cathodes. The device manufacturing aspect of the flat panel field emission display, in particular relates to a flat panel display with a circular gate sidewall emission structure and its manufacturing process. Background technique [0002] Display devices have penetrated into various fields of modern society. With the rapid development of information display technology, higher and higher requirements are put forward for display technology and display devices. Since carbon nanotubes are fired with excellent field emission characteristics, they have attracted the attention of many researchers. Carbon nanotubes have a high aspect ratio and are very suitable as cold cathode mater...
