Abstract

This invention relates to a panel display with doped-polysilicon field emission cathode array structure and its process technology, in which, the display includes a sealed vacuum cavity composed of a cathode panel, an anode panel and surrounding glasses, anode conduction strips etched on the anode panel and fluorescence powder layer on the conduction strips, a supporting wall and getter attached elements, in which, a doped polysilicon field emission cathode array structure is prepared on the cathode panel to reduce the distance between the cathode and the grating, control the working voltage of the grating and reduce the current of the control grating.

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 device manufacturing aspect of the field emission display particularly relates to the manufacturing process of a field emission flat display device with a doped polysilicon field emission cathode array structure and a carbon nanotube cathode. Background technique [0002] Carbon nanotubes have a small tip curvature radius, high aspect ratio, good field emission characteristics and excellent physical and chemical stability. Carbon nanotubes themselves are coaxial, tubular substances that emit large amounts of electrons when an applied voltage is applied. The flat panel display using carbon nanotubes as the cathode material is a new type of field emission d...
