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 structures of hollow bottom grid array on 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 trapping electron beam by grid structure, increases brightness of the display, and enhances area and quantity of electron emission of Nano carbon tube cathodes. 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 flat panel field emission display, in particular relates to a flat panel display with hollow bottom grid array structure and its manufacturing process. Background technique [0002] Carbon nanotubes have a small tip curvature radius, exhibit excellent field emission characteristics, and are very suitable for use as cold cathode materials for field emission display devices. The field emission display is a display device that uses the electron beam emitted by the field emission cold cathode to bombard the phosphor layer to emit light. It has a working principle similar to that of the cathode ray tube display, and also inherits the high...
