Problems solved by technology

[0003] In most of the display devices reported so far, the control mode in which the gate structure is located above the carbon nanotube cathode structure is adopted. The manufacturing process is relatively simple, and the control effect of the gate structure is significant, but the gate voltage remains high. , the grid current is too large, and the effective electron emission area of ​​the carbon nanotube cathode is small, etc. are also unfavorable factors.

Abstract

The invention relates to a flat panel display with an open square bottom grid control structure and its manufacturing process, comprising a sealed vacuum chamber composed of an anode glass panel, a cathode glass panel and surrounding glass frames; an anode conductive layer arranged on the anode glass panel And the phosphor layer prepared on the anode conductive layer; the support wall structure and getter accessory elements between the anode glass panel and the cathode glass panel, and the grid lead layer, carbon nanotubes and open squares are arranged on the cathode glass panel The bottom gate control structure can further increase the electron emission area of ​​the carbon nanotube and reduce the working voltage of the grid structure, and 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 an open square bottom gate control structure and its manufacturing process. Background technique [0002] The carbon nanotube cathode field emission display is a flat display device that uses the electron beam emitted by the carbon nanotube cold cathode to bombard the phosphor layer to emit visible light. It has high brightness, high definition, high luminous efficiency, low power consumption, and thin volume. It can be widely used in various information display equipment fields such as large-screen wall-mounted TVs, large outdoor billboards, and ...
