Key Words

• Nanotube

• LCD Liquid Crystal Display

• Technology

• Fullerene

3
Nanotube

• A hollow, cylindrical or toroidal molecule made
  of one element, usually carbon.
• Nanotubes are being investigated as
  semiconductors and for uses in nanotechnology.
• A microscopic tube whose diameter is measured in
  nanometers.

4
LCD Liquid Crystal Display

• a method of displaying readings continuously, as
  on digital watches, portable computers, and
  calculators, using a liquid-crystal film, sealed
  between glass plates, that changes its optical
  properties when a voltage is applied.

5
Technology

• The application of science, especially to
  industrial or commercial objectives.
• The scientific method and material used to
  achieve a commercial or industrial objective.
• Electronic or digital products and systems
  considered as a group

6
Fullerene

• any of a class of molecules of carbon having a
  roughly spherical shape

7
What is a Carbon Nanotube?

• A carbon nanotube is a one-atom thick sheet of
  graphite rolled up into a seamless cylinder with
  diameter of the order of a nanometer

• A Nanometer is 1/100,000,000 of a meter and
  nanotubes range in size of 3 nm to 30 nm

Who first Discovered Carbon Nanotubes?

• In 1991, a Japanese scientist by the name of
  Sumio Iijima discovered fullerene related carbon
  nanotubes

• He also noted that there were approximately 80
  different types all with distinct properties

• Carbon Nanotubes can be up to 50 times stronger
  than steel

11
So Why Carbon Nanotube Displays?

• Carbon Nanotube Displays require much less energy

• Feature more-vivid colors than LCDs

• Nanotechnology is making displays potentially
  less expensive allowing displays to be larger and
  cheaper than before

12
So When will I see a Carbon Nanotube Display?

• According to companies like Microsoft, Canon, and
  Toshiba we can expect to see Carbon Nanotube
  Televisions and Computer Monitors by 2007 or 2008

Carbon Nanotube Televisions are projected to
start at around 1,300 but a price for computer
monitors has not been released
