Light-emitting display with inclined semicircular gating pointed straight pentagonal pyramid cathode structure

Abstract

The invention discloses a light-emitting display with an inclined semicircular gating pointed straight pentagonal pyramid 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.

Problems solved by technology

For example, due to the large distance between the gate and the carbon nanotube layer, the gate operating voltage is very high, which does not meet the mainstream requirements of low-voltage and low-power-loss flat-panel display devices

Due to the unreasonable structure between the gate and the carbon nanotube layer, the control performance of the gate to the carbon nanotube layer is poor, that is, the amount of electrons emitted by the carbon nanotube cannot change with the change of the gate operating voltage. This will invisibly greatly increase the power loss of the overall light-emitting display. In severe cases, with the loss of the ability to regulate the gate operating voltage, the light-emitting display will be scrapped.

In terms of carbon nanotube cathodes, in view of the unreasonable structure of the cathode, the electron emission efficiency of carbon nanotubes is seriously reduced, and more carbon nanotubes cannot participate in electron emission. out of the question
