Field emission image uniformity improvement by laser treating carbon nanotube powders

Carbon nanotube powders were synthesized by arc discharge method and incorporated into the paste to be applied in the screen printing process. It was investigated that the field emission image uniformity was efficiently improved by laser treating carbon nanotube powders. The laser energy burned out carbon particles to reveal more carbon nanotubes and graphitized carbon nanotubes. In addition to uniformity improvement, field emission properties were also reinforced after laser treating. For instance, turn-on voltage decreased from 3.2to2.2V∕μm, while field enhancement factor increased from 2200 to 2900.

59.2: Invited Paper: Development of CNT-FED by Printing Method

4″ to 20″ carbon nanotube field emission display (CNT-FED) and back light unit (CNT-BLU) have been fabricated by printing method. The gated arrays of cathode plates were fabricated by screen printing and photolithography processes. Taiwanese research results on FEDs are also described.

45.3: Pentacene Organic Thin-Film Transistor Integrated with Color Twisted Nematic Liquid Crystals Display (CTNLCD)

Pentacene Organic Thin-Film Transistor (OTFT) integrated with Color Twisted Nematic Liquid Crystals Display (CTNLCD) has been developed. This display used photolithography, pentacene deposition, color filter and TNLC. In addition, we successfully develop the OTFT passivation layer process to avoid the damage of TNLC. Above these processes are integrated to manufacture the 3 inch CTNLCD panels with 64 ×128 pixels.

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.

7.3: Novel Structure of Carbon Nanotubes Backlight Unit

A novel structure of carbon nanotubes backlight unit (CNT-BLU) was introduced to improve the uniformity. From the calculation and experimental verification, large improvement on uniformity can be observed. Benefiting from these important results, the new planar backlight technology has chances to proceed to mass production and reduce the cost of optical films such as diffuser and/or brightness enhancement film. Based on the structure, the printed CNT-BLU has the potential to replace traditional backlight technology because of its good properties like the simple processes, easy to large scale, low surface Temp and Hg-free…etc.

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.
