The invention relates to a light-emitting display with a different-radian curved single-gate control double-hung conical ring surface cathode structure. The light-emitting display comprises a vacuum chamber formed by a front compressive hard glass plate, a rear compressive hard glass plate and a transparent glass frame, wherein an anode square electrode layer, an anodic epitaxial silver layer connected with the anode square electrode layer and a fluorescent powder layer prepared on the anode square electrode layer are arranged on the front compressive hard glass plate; the different-radian curved single-gate control double-hung conical ring surface cathode structure is arranged on the rear compressive hard glass plate; and a getter and a hidden support beam auxiliary component are arranged in the vacuum chamber. The light-emitting display has the advantages of being low in manufacturing cost, high in brightness, excellent in light-emitting brightness adjustability and simple in manufacturing structure.

AI Technical Summary

Problems solved by technology

In terms of the fabrication area of ​​the carbon nanotube layer, if the fabrication area of ​​the carbon nanotube layer is too large, the pixels of the light-emitting display will be reduced, and the display resolution of the display cannot be improved; but if the fabrication area of ​​the carbon nanotube layer is too small, there will be no Enough carbon nanotubes for electron emission are not conducive to improving the cathode current of light-emitting displays, so it is necessary to research and develop the production area and production process of the carbon nanotube layer; in terms of the production structure of the carbon nanotube layer, even if there is a larger carbon However, there is not enough effective carbon nanotubes to participate in electron emission, which also fails to achieve the purpose of increasing the cathode current of the light-emitting display. Therefore, it is also necessary to study the structure of the carbon nanotube layer.

Second, the gate operating voltage is significantly higher

If the effective distance between the gate and the carbon nanotube layer is too large, this will cause the gate operating voltage to increase, thereby causing high power loss in the light-emitting display, which does not meet the requirements of flat low-voltage display devices; If the effective distance of the nanotube layer is too small, it is very easy to cause electrical breakdown between the two, and at the same time, it also increases the requirements for the insulation performance of the insulating material between the two, and increases the production cost of the light-emitting display.

In addition, there are also problems such as unreasonable gate fabrication structure and too much interception of electrons emitted by carbon nanotubes at the gate, which also need to be solved together.
