Problems solved by technology

However, in most of the current flat panel display devices, the working voltage of the gate structure is high, and it is difficult to connect with the conventional integrated driving circuit, and making a dedicated integrated driving voltage will only further improve the overall device. cost, which does not meet the quality requirements of flat panel devices

Abstract

The flat panel display includes following parts: sealed vacuum cavity composed of glass faceplate of anode, glass faceplate of cathode, and glassed-in frame; anode conductive layer on the glass faceplate of anode, and phosphor layer on the anode conductive layer; the support wall structure between the glass faceplate of anode and the glass faceplate of cathode, and accessorial components for getter; cathode conductive layer, Nano carbon tube, and beveled circular truncated cone grid controlled cathode structure setup on the glass faceplate of cathode. The invention raises efficiency and quantity of electron emission of cathode in Nano carbon tube, reduces operating voltage of grid electrode so as to be in favor of preparing flat device in high quality. Advantages are: stable and reliable fabricating procedure, simple technique, low fabricating cost, and ordinary 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 a frustum-inclined gate-controlled cathode Structured flat panel display and its manufacturing process. Background technique [0002] The flat field emission display device of carbon nanotube cathode is a kind of vacuum microelectronic flat panel display device, which makes full use of the cold field emission principle of carbon nanotube cathode, and relies on the low working voltage of the grid structure to make the carbon nanotube cathode emit A large number of electrons bombard the phosphor layer in the anode structure to emit visible light. The working principle of this display is actually an improvement of the working principle of the cathode ray tube display, so it can meet or exceed th...
