Planar display device with float-grid structure and its production

Abstract

A flat display and the manufacture craft with the floating grid structure, including: the sealed vacuum cavity that forms by the cathode board, the anode board and the glasses encircling frame; the anode board with the photoetching conducting layer and the fluorescent layer preparing on it; the cathode board with the cathode conducting layer, the vegetal carbon nanometer tube cathode and the grid conducting layer that controls the electron transmission; the support wall structure and the getter accessorial component; fixes floating grid structure for controlling the carbon nanometer tube cathode with the strong grid structure on the cathode board, can improve the manufacture successful rate of the whole parts, reduce the manufacture cost and simplify the manufacture craft, enhance the controlling effect of the grid structure to the carbon nanometer tube cathode.

Description

technical field [0001] The invention belongs to the fields of plane display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to the manufacture of flat panel field emission displays, in particular to flat panels for carbon nanotube cathodes. The content of device fabrication of field emission display, especially related to the fabrication process of field emission flat panel display device with floating gate structure and carbon nanotube cathode. Background technique [0002] Carbon nanotube is a coaxial tubular substance with unique geometric shape, small tip curvature radius, high aspect ratio and stable physical and chemical properties. It is an ideal material for emitting cathodes. At present, the preparation methods for carbon nanotube cathodes can be roughly divided into two categories, namely: direct growth method and transplantation method. The field emission characteristics of carbon nan...

Problems solved by technology

But not all electrons fly vertically to the anode glass panel, and some electrons will fly to the supporting wall structure in a disorderly manner; when the electrons bombard the supporting wall structure, secondary electrons will be excited from the supporting wall structure, and other The emission of secondary electrons will have a certain impact on the display device, which in turn will affect the display image quality of the device, and in severe cases will lead to the burning and scrapping of the entire display device
