Beneficial effect：The present invention possesses following significant progressive：

First, type of being dehisced on described flat lower arc is solely gated in the more edge cathode constructions of ring concave surface probe, has been made recessed The more edge cathode constructions of face probe.Wherein, to surround, negative electrode is recessed to bottom out lower floor to the curved surface top edge of two layers of negative electrode boundary layer extended line The hollow circular of surrounding, has very big electrode edge；The curved surface lower edge of two layers of negative electrode boundary layer extended line is then around the moon The extremely recessed annular with sawtooth pattern gap bottomed out around lower floor, equally also has very long electrode edge.It is cloudy in CNT In the field emission light-emitting display of pole, there is distinctive " fringe field enhancing " phenomenon, this phenomenon is at the concave surface more edges of probe It is fully used in cathode construction.Being prepared in the carbon nano tube surface of negative electrode boundary layer transition zone marginal position can form more Powerful electric-field intensity, it will also launch more electronics, this is for further enhancing the luminous intensity of active display, changing The luminous gray scale controllability of kind active display is all beneficial.

Secondly, type of being dehisced on described flat lower arc is solely gated in the more edge cathode constructions of ring concave surface probe, has been made flat Dehisced on lower arc type gate pole.Wherein gate pole dehisce electrode plane layer mainly it is recessed to negative electrode bottom out boundary layer upper right side curved surface it is following The CNT of edge position carries out electron emission control, and gate pole dehisces electrode cambered surface layer then major regulatory negative electrode is recessed to bottom out boundary layer The electron emission of the CNT of the curved surface upper marginal position of upper right side；Gate pole electrode auxiliary connection layer of dehiscing is then further Ensure that additional gate pole potential smoothly while can be delivered to that gate pole dehisces electrode cambered surface layer and gate pole is dehisced electrode plane layer.When After gate pole applies operating voltage, powerful electric-field intensity will be formed in carbon nano tube surface, forces carbon nanotube emission to go out A large amount of electronics；Meanwhile CNT institute launching electronics quantity number, can become with the change of gate work voltage swing Change.This all embodies strong performance of control of the type gate pole to carbon nanotube cathod of being dehisced on flat lower arc.

3rd, type of being dehisced on described flat lower arc is solely gated in the more edge cathode constructions of ring concave surface probe, CNT Prepare on negative electrode boundary layer transition zone.Negative electrode boundary layer transition zone is surrounded on that negative electrode is recessed to be bottomed out around lower floor, has very big table Area, the area for preparing of this carbon nanotube layer for allowing for being prepared on negative electrode boundary layer transition zone increase；Meanwhile negative electrode boundary layer Concave shape is presented in transition zone, and this can cause the area for preparing of carbon nanotube layer further to expand.So, the quantity of CNT Naturally increase.Remove outside some CNTs impaired in manufacture craft, there are more CNT energy Field-electron emission is simultaneously participated in, is very helpful for the anode working current for improving active display.

In addition, type of being dehisced on described flat lower arc is solely gated in the more edge cathode constructions of ring concave surface probe, it is not necessary to special Different display making apparatus, is not related to special display making material, and these measures are both contributed to further reduce and lighted The cost of manufacture of display.

Except the technical problem of invention described above solution, form the technical characteristic of technical scheme and by these skills Caused by the technical characteristic of art scheme outside advantage, it is cloudy that type of being dehisced on flat lower arc of the invention solely gates the ring concave surface more edges of probe The other technical characteristics included in other technologies problem that the active display of pole structure can solve, technical scheme and these The advantages of technical characteristic is brought, it will be described in more detail with reference to accompanying drawing.
