AI Technical Summary

Problems solved by technology

Second, the effective emission area of ​​carbon nanotubes is too small
Third, the problem of excessive gate current is also prominent
However, if the gate current is too large, it means that the number of field emission electrons trapped by the gate is too large, which will greatly reduce the luminous brightness and luminous intensity of the light-emitting display.

Abstract

The invention discloses a light-emitting display with an inclined parallel crossed gating square pointed triangular roof-type cathode structure, and the display comprises a vacuum chamber which consists of a cathode packaging plate, an anode packaging plate and a transparent glass frame. The anode packaging plate is provided with an anode conducting layer, a fluorescent powder layer prepared on the anode conducting layer, and an anode external extending line layer connected with the anode conducting layer. The cathode packaging plate is provided with an inclined parallel crossed gating square pointed triangular roof-type cathode structure. The display also comprises a supporting column located in the vacuum chamber, and a getter attaching element. The display is simple and feasible, is high in light brightness, and is high in finished rate.

Description

technical field [0001] The present invention belongs to the fields of vacuum science and technology, optoelectronic science and technology, integrated circuit science and technology, display technology, microelectronics science and technology and nano science and technology, and relates to a flat field emission display The manufacture specifically relates to the manufacture of a planar field emission luminescent display of a carbon nanotube cathode, in particular to a luminescent display with a slanted straight parallel fork-gated mouth-pointed triangular-top cathode structure and its manufacturing process. Background technique [0002] Carbon nanotubes are a new type of tubular objects with a diameter of about tens of nanometers; under the action of a sufficiently large external electric field, carbon nanotubes will emit a large number of electrons without applying other energy, forming a unique cold field Therefore, carbon nanotubes are also an excellent cold cathode mater...
