Abstract

This is a flat displayer of petaline shape low grid cathode structure and its production process. It includes a sealed vacuum chamber formed by a anodic glass panel, a cathode glass panel and surrounded glass frame; on the anodic glass panel is a conducting layer coated with fluorescent; a supporting wall between the anodic and cathode panel and a getter; on the cathode glass panel are a grid down-lead layer, carbon nanotube and petaline shape low grid structure, which is capable of increasing the control function and efficiency of the grid, so increase the display quality.

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 production aspect of the flat panel field emission display particularly relates to a flat panel display with a petal-shaped lower grid-controlled cathode structure and its manufacturing process. Background technique [0002] Carbon nanotube field emission display technology will shine brightly on the stage of display technology. The principle is that electrons emitted by carbon nanotube cold cathodes do not require additional energy. The electron beam is narrow and has high brightness. Visible light is emitted by bombardment. This kind of display is very thin, light, and saves energy. Its higher display brightness makes it easy to read text in sunlight. T...
