Mitron；Gate pole twill electrode upper strata, gate pole twill electrode lower floor and layer presentation diagonal shape arrangement after gate pole twill electrode, this
Sample, same gate work voltage, it becomes possible to regulate and control to greater area of carbon nanotube layer enables to more carbon nanometers
Pipe is while launching electronics, this can for the luminous gray scale of the greatly luminosity of improvement active display, enhancing active display
Modulability is very favorable.
Secondly, in many hollow face cathode constructions of projection cake layer of three described cambered surface twill simple gate controls, made more raised
The hollow face negative electrode of cake layer.Cake layer is truncated cone-shaped, the carbon nanotube layer on cake layer can be raised, so that CNT
Coverage becomes smaller between layer-gate pole, reaches the mesh for reducing gate work voltage, reducing active display power attenuation
's；Cake layer is the hollow round table shape of depression, so that each cake layer has electrode edge very long, in addition, cake layer
Quantity is eight, and so overall negative electrode low-lying area face conductive layer just has longer electrode edge.Therefore, for well-known " side
Edge electric-field enhancing " phenomenon is fully used.The electrode edge of negative electrode low-lying area face conductive layer, electric-field intensity can be further enhanced,
The CNT of the position can launch more polyelectron such that it is able to significantly increase the luminous intensity and luminance of active display
Degree.
3rd, in many hollow face cathode constructions of projection cake layer of three described cambered surface twill simple gate controls, prepared by CNT
On the conductive layer of negative electrode low-lying area face.Negative electrode low-lying area face conductive layer is located above the cake layer that depression hollow round table shape is presented, so
The surface area of negative electrode low-lying area face conductive layer is very big, and this, can that is, the area for preparing of carbon nanotube layer has obtained effective expansion
The quantity of carbon nanotubes for participating in field-electron emission becomes many.Since having more CNTs can launch a large amount of electronics, that
Obtain in active display bigger anode working current namely easily thing.This is for reducing active display
Power consumption, improve active display luminosity be all substantially it is beneficial.
Additionally, in many hollow face cathode constructions of projection cake layer of three described cambered surface twill simple gate controls, it is not necessary to special
Making apparatus, special manufacture craft is not needed more, and this can further reduce the cost of manufacture of Integral luminous display.
Except invention described above solve technical problem, constitute technical scheme technical characteristic and by these skills
