Description
Technical field
The invention belongs to photoelectron science and technology field, integrated circuit science and technology field, display technology field, micro-
Electronics Science and Technology field, vacuum science and technical field and the field that intersects in nanometer science and technology field, relate to
And to the making of plane Flied emission active display, and in particular to the plane Flied emission active display of carbon nanotube cathod
Make, be related specifically to a kind of active display for inclining the clamp type simple gate control class anise big side cathode construction of pyramid.
Background technology
Field emission light-emitting display be it is a kind of can show dynamic, the display device of still image, with display image matter
Amount is high, operation temperature area is wide, visual angle is big, the low superiority of power consumption.In the negative electrode of Flied emission active display prepares material, carbon is received
Mitron is a kind of cold cathode of excellent performance.For the preparation technology of CNT, the introducing of screen printing technique is exactly
One all well and good selection；This causes the carbon nanotube layer for making the carbon nanotube layer of large area and making specific pattern, all
Become to be highly susceptible to realizing.In the field emission light-emitting display of three-stage structure, between anode and carbon nanotube cathod, introduce
Gate structure；Due to the distance between gate pole and carbon nanotube cathod very little, this causes the gate work voltage of very little with regard to energy
The enough electric-field intensity formed in carbon nano tube surface needed for CNT carries out electron emission, forces carbon nanotube emission largely electric
Son.With the research to carbon nano-tube material so that the research and development process of field emission light-emitting display has been accelerated.
But undeniably, also exist in the carbon nano tube field-emission active display of three-stage structure a large amount of undecided
Technical barrier.First, the field-electron emission efficiency of CNT.CNT carries out field-electron emission, and this is to be formed
The premise of active display anode working current；If CNT has very low electronic transmitting efficiency, then also just cannot shape
Into big active display anode working current, just cannot more be referred to as indexs such as the luminosity for improving active display
.In current field emission light-emitting display, the electronic transmitting efficiency of CNT is generally low, more there is substantial amounts of carbon nanometer
Pipe just fails to participate in field-electron emission at all, and this needs to solve.Second, the ability of regulation and control of gate pole is very weak.When the applying on gate pole
After operating voltage, it is impossible to enough to form strong electric field intensity on carbon nano tube surface top, also just fail to force CNT to carry out
Electron emission；Or, under the precondition for forcing CNT to carry out electron emission, carbon nanotube emission electron amount
Number, do not regulated and controled by gate work voltage but.These are all the weak specific manifestations of gate pole ability of regulation and control, it is necessary to be ground
Study carefully solution.3rd, carbon nanotube layer prepares area very little.Small carbon nanotube layer prepares area, also implies that carbon nanometer
The quantity of pipe becomes too small, and this is obviously unfavorable for improving and improving the luminosity of active display.But it is how reasonable
Further increase carbon nanotube layer prepares area and improves the making structure of carbon nanotube layer, in addition it is also necessary to constantly explored.
Property simple and easy to apply that problem, gate pole make in addition, the making structure of gate pole-carbon nanotube cathod influences each other etc., it is also desirable to one
And solve.Additionally, in the manufacturing process of actual Flied emission active display, actual fabrication technological feasibility, it is fabricated to
This and be fabricated to power etc., also can not be ignored.The solution of these technical barriers, is worth thinking over.
