Light-emitting display with misaligned relative angular arc-ring cathode three-curve trunk curved door control structure

Abstract

The present invention discloses a light-emitting display with a misaligned relative angular arc-ring cathode three-curve trunk curved door control structure. The light-emitting display comprises a vacuum enclosure and a getter accessory element arranged in the vacuum enclosure. The vacuum enclosure is composed of a glass-sealed upper separator, a glass-sealed lower separator and a strip-shaped transparent frame; there are an anode-permeable film bottom layer, an anode outer-line thick silver layer and a thin light-emitting layer on the glass-sealed upper separator, the anode-permeable film bottom layer is connected with the anode outer-line thick silver layer, and the thin light-emitting layer is formed on the anode-permeable film bottom layer; and a misaligned relative angular arc-ring cathode three-curve trunk curved door control structure is formed on the glass-sealed lower separator. The light-emitting display provided by the present invention has the advantages of high light-emitting brightness of the display, a low cost, and a reliable process.

Description

technical field [0001] The invention belongs to the fields of optoelectronic science and technology, nanometer science and technology, integrated circuit science and technology, vacuum science and technology, plane display technology and microelectronic science and technology, and relates to planar 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, and in particular relates to a luminescent display with a three-curved main-line curved gate structure of a cathode with a staggered relative angular arc torus. Background technique [0002] Carbon nanotubes are tubular materials with diameters on the order of nanometers, which have high mechanical strength and very good electrical properties. In a vacuum environment, carbon nanotubes can emit electrons only by applying an external voltage. In current field emission flat panel displays, carbon nanotubes hav...

Problems solved by technology

[0003] However, there are still many technical problems to be solved in the field emission light-emitting display of the triode structure.

For example, one, the control ability of the gate electrode to the carbon nanotube cathode is very weak

The specific performance is: when the gate voltage is applied to the gate, the number of electrons emitted by the carbon nanotube cathode is very small, or many carbon nanotubes do not emit electrons at all. From a macro perspective, it is impossible to form a large The current of the luminous display, which is not helpful to improve the technical indicators of the luminous display such as luminous brightness, luminous gray scale, etc., but also makes the gate electrode production lose its original meaning

Due to the short d
