Abstract

The invention relates to a flat panel display with hat-shaped bottom grid-controlled cathode structure and its manufacturing process, which includes a sealed vacuum chamber composed of an anode glass panel, a cathode glass panel and surrounding glass frames; layer and the phosphor layer prepared on top of the anode conductive layer; the supporting wall structure and getter accessory components between the anode glass panel and the cathode glass panel, and the grid lead layer, carbon nanotubes and cap type on the cathode glass panel Bottom-gate-controlled cathode structure; it can reduce the working voltage of the grid, improve the display brightness of the overall device, and reduce the working current of the grid. It has the advantages of stable and reliable manufacturing process, simple manufacturing process, low manufacturing cost and simple structure.

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 particularly relates to a flat panel display with a cap-type bottom grid-controlled cathode structure and its manufacturing process. Background technique [0002] Carbon nanotubes have small tip curvature radius, high aspect ratio, good physical and chemical properties, and excellent field emission characteristics, making them very suitable for use as field emission cold cathode materials. Using this principle, the device fabrication of field emission flat panel display is carried out. Carbon nanotube cathode field emission display is a new type of flat panel display device, which combines the a...
