Applied Nanotech To Introduce 14-In Black And White Carbon Nanotube TV
Nano-Proprietary, Inc. announced that its subsidiary Applied Nanotech, Inc. (ANI) will reveal to the world their 14” diagonal black and white carbon nanotube TV at International Display Workshop 2003 (December 3-5) in Fukuoka Japan (http://idw.ee.uec.ac.jp/). This prestigious yearly display conference is sponsored by the Society for Information Display and The Institute of Image Information and Television Engineers of Japan.
ANI will be presenting three substantial breakthroughs in the development of displays - excellent uniformity and gray scale; techniques that considerably lowers the capital investment for manufacturing TVs; and improved characteristics of electron emission from carbon nanotubes making the devices compatible with low cost (CMOS) drivers’ technology.
As described in patent application No. 60/254,374, publication No. 2002-0110996 A1 (“Low work function material”), ANI perfected a process of dopping carbon nanotubes with certain alkali materials. To improve the electron emission process, it is very important to lower the barrier encountered by electrons at the surface of the carbon nanotube. By treating the carbon nanotubes with alkali material, ANI proved that it is much easier to extract electrons from carbon nanotubes. Threshold voltages lower than one volt per micrometer can be achieved, resulting in driving voltages lower than 50 volts enabling low cost electronic drivers (CMOS compatible) to be applied.
Given that the cost of electronic drivers generally comprises 50% of the cost of a display and due to the low capital investment for the manufacturing process developed by ANI, carbon nanotube electron emission technology is emerging as a stellar candidate to achieve affordable large area entertainment and home TVs.
