22.3: A Reflective‐Type Carbon Nanotube Field Emission Display

A 3.5-inch, 60×120 pixels, reflective-type carbon nanotube emitter field-emission display has been fabricated by thick-film process. A seven-segment numerical indicator showing digit image was also demonstrated using opposed diode structure as comparison. The technical development, including design and fabrication of the nanotube emitters, phosphor, and vacuum package process was described.

24.4: Planar Triode Structure Carbon Nanotubes Field Emission Display

A new planar triode structure of CNT-FED has been fabricated. The gate electrode and the CNTs emitters were almost on the same plane. The gate pulls out the electrons from the both side CNTs emitters. The electron beam would be focus on the top of the gate electrode.

P‐46: Color Carbon Nanotube Field Emission Display

A 10-inch, 240 ×320 pixels, triode structure color carbon nanotube field emission display (CNT-FED) was fabricated after screen printing, photolithography and vacuum sealing process. The new normal on driving method was applied in triode CNT-FED, and the resolution was improved better than normal off FED.

Low-cost fabrication of triode structure carbon nanotube field emission display

A triode structure carbon nanotube field emission display (CNT-FED) was fabricated by screen printing and sandblasting process.

P‐119: A Highly Precise Processes for Cathode Structure of CNT‐FEDs

In this work, the cathode structure of carbon nanotubes field emission display (CNT-FED) was fabricated by both the screen printing and photolithography processes. In order to get the precise cathode structure and lower processes cost (reducing one or two mask), bottom-exposure method based on existed CNT layer to be the mask, and then photo-sensitive dielectric paste was executed. Dielectric holes are made precisely directly over CNTs emitters, regardless of sintering shrinkage phenomenon and alignment deviation in the photolithography process. In this manuscript, 10″ normal triode structures are demonstrated.

Field emission display using carbon nanotubes as emitters

A fully sealed field emission display (FED), indicator, using carbon nanotubes (CNTs) as emitters is examined. The CNTs chunk, synthesized by arc discharge, were crushed, mixed with conductive pastes and then screen-printed on glass for the cold cathode. And the anode plate, an ITO glass printed P15 phosphor, was separated from cathode using 90 micrometers spacers. The indicator display performed a turn-on voltage as low as 250 V, and the emission current density 2.2 mA/cm2 under 300 V with brightness of 500 nits. The pixels, driven by open drain IC with 5 V gate voltage, showed the clock image which indicated the application of CNTs-FED. No significant degradation of this performance was observed during 1000 mins testing. The influence of printing condition and surface treatment process on the emission characteristics will also be discussed in this letter.

Field emission characteristics of carbon nanotube emitters using screen-printing technique

A carbon nanotube emitter with high uniformity, adhesion and emission current has been formed by screen printing. The raw carbon nanotubes (CNTs) chunk were crushed, purified, dispersed, mixed with organic additives and then screen printed on Ag electrode. After burning out the organic additives under two thermal cycles, the surface of CNTs emitters were treated. The treated emitters showed a better emission characteristic than untreated emitters.
