Problems solved by technology

In most current field emission displays, either the gate operating voltage required to force the carbon nanotubes to emit a large amount of electrons remains high, or the gate current is too large, or the gate current is too high at a low gate voltage. The anode current is too small, that is to say, there are not...

Abstract

The invention relates to a flat panel display with a multiple coaxial column surface and lateral grate as well as its manufacturing technique, which comprises a sealed vacuum cavity composed of an anode glass faceplate, a cathode glass faceplate and a glass enclosing frame; an anode conductance layer positioned on the anode glass faceplate; a fluorescent powder layer prepared on the anode conductance layer; a supporting wall structure and an auxiliary component of getter that are arranged between the anode glass faceplate and the cathode glass faceplate; a grid lead layer, a carbon nanometer tube and a multiple coaxial column surface lateral grate structure on the cathode glass faceplate. Therefore, the invention is able to further lower down the working voltage of the grid structure and improve the quality of displayed image in the whole device. Besides, the invention has the advantages of reliable and stable manufacturing process, simple manufacturing technique, low manufacturing cost and simple structure.

Description

Technical field [0001] The present invention belongs to the intersecting fields of flat panel display technology, microelectronics science and technology, vacuum science and technology, and nanoscience and technology, and relates to the production of flat-panel field emission displays, and specifically to carbon nanotube cathodes. The content of the device manufacturing of flat-panel field emission displays, in particular, relates to a flat-panel display with a multi-coaxial cylindrical side gate control structure and its manufacturing process. Background technique [0002] The carbon nanotube field emission display is a new type of active light-emitting fully cured flat panel display. The working principle of this display is almost the same as that of the traditional cathode ray tube display. It uses electron beams to bombard the phosphor layer to emit visible light. , It retains the advantages of high brightness, high display image quality, fast response speed and large viewing...
