Luminescent display with bilateral ring flat concave angle spine and cathode combination slope surface gate controlled structure

Abstract

The invention discloses a luminescent display with bilateral ring flat concave angle spine and cathode combination slope surface gate controlled structure. The display comprises a vacuum chamber formed by an upper flat glass sealing plate, a lower flat glass sealing plate and a transparent glass frame, an anode film connection layer on the upper flat glass sealing plate, a phosphor layer formed on the anode film connection layer and an anode silver outer conductive layer connected with the anode film connection layer, a bilateral ring flat concave angle spine and cathode combination slope surface gate controlled structure on the lower flat glass sealing plate as well as a getter in the vacuum chamber and isolation insulation wall attached components. The luminescent display of the invention has the advantages of being manufactured at low production cost and through simple production process while achieving high brightness.

technical field [0001] The present invention belongs to the fields of integrated circuit science and technology, vacuum science and technology, optoelectronic science and technology, microelectronics science and technology, nanometer science and technology and plane display technology, and relates to plane field emission luminescence The manufacture of the display 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 gating structure on the slope surface of a double-side ring flat concave sharp angle thorn cathode combination and a manufacturing process thereof. Background technique [0002] With the introduction of screen printing technology, the development of field emission light-emitting display manufacturing technology has been promoted. Not only can the production of large-area carbon nanotube cathodes be realized, but also the production cost of field emission ...

AI Technical Summary

Problems solved by technology

Second, the fabrication area of ​​the carbon nanotube cathode is too small

Without a certain amount of carbon nanotubes for electron emission, it is impossible to reach the rated operating current required by the light-emitting display, so it is not surprising that the various image technical indicators of the light-emitting display have declined

Third, the gate-cathode distance is too large

Because the distance between the gate and the cathode is too large, in order to achieve the electric field strength necessary for carbon nanotubes to emit electrons, it i
