Abstract

The invention relates to a flat panel display with an inverted staggered ballast structure and its manufacturing process, comprising a sealed vacuum chamber composed of a cathode glass panel, an anode glass panel and surrounding glass frames; layer and the phosphor layer prepared on the anode conductive layer; the support wall structure and getter accessory components between the anode glass panel and the cathode glass panel, and the control grid, carbon nanotube cathode and inverted fault on the cathode glass panel Arrangement ballast structure; by adjusting the gate voltage, the current flowing through the carbon nanotube cathode can be further adjusted, thereby adjusting the ability of the carbon nanotube cathode to field-emit electrons, so that the overall carbon nanotube cathode can uniformly and stably emit a large number of electrons The effect of further improving the luminous uniformity of the whole device has the advantages of stable and reliable manufacturing process, simple manufacturing process, low manufacturing cost and simple structure.

Description

technical field [0001] The present invention belongs to the fields of plane display technology, electronic science and technology, vacuum science and technology, integrated circuit science and technology, and nano science and technology, and relates to device fabrication of flat panel field emission displays, in particular to It relates to the device manufacture of flat panel field emission display with carbon nanotube cathode, especially relates to a flat panel display with inverted staggered ballast structure and its manufacturing process. Background technique [0002] Carbon nanotubes have a small tip curvature radius, high aspect ratio and good electrical conductivity. When an appropriate voltage is applied, a large number of electrons will be emitted, forming a unique cold field emission phenomenon, which has already attracted many researchers. of great importance. The field emission flat panel display made of carbon nanotubes as the cathode material is a new type of h...
