Problems With Indium

• Shortage of Indium
• Required for LCD, PDP almost every other
  display technology
• sourced from Russia and Canada
• Part of the indium tin oxide layers (ITO)
• primary conductor used on glass substrates
  because of wetting properties

Problems With Indium

• carbon Nano Tube
• Possible replacement for ITO
• Uses Tunnel Effect
• grown instead of sputtered
• adheres to glass

• higher resistance to ion sputtering
• longer panel life
• high exoelectron emission
• provides priming particals
• Crystal Emissive Layer
• Increase of phosphor emissions

16
PDP

• Increase of Dielectric constant of barrier ribs
• Lower power loss
• Low Te and spatially Distributed Drive
• Higher ionization/excitation rates
• High Xe Content Drive

OLED
21
OLED

• Light from radiative recombination of electrons
  and holes
• Action from an atom in an excited state undergoes
  a transition to ground
• releases a photon
• Primary parts are
• hole donor
• electron donor
• emissive layer

23
OLED

• Advantages of organic semiconductors
• molecules are held together by weak van der waals
  forces
• carrier mobilities are low
• typically less than 1cm2/v-s
• high fluorescence efficiencies
• epitaxy is not required
• properties can be tailored with Types of
  Materials
• can be fabricated on large substrates
