Definitions

  • Example 5b 440nm SiO 2 Nanoparticles Coated by Roll-to-Roll Process with Small Nanoparticles
  • Electroluminescence measurements showed enhanced OLED light extraction from the nanoparticle coated pixels. An improvement of 50% at current densities between 2-20 mA/cm 2 was shown with this modification.
  • Example 7 Light Extracting OLED Substrate having Nanoparticles Overcoated by High Index Polymer Applied in Roll-to-Roll Process.
  • the 5mm x 5mm shadow mask was then realigned, and 200nm of Al metal was deposited to form the cathodes contacting the tops of the pixels.
  • This process provided OLED devices containing several independently addressable 5mm x 5mm pixels with 4 pixels disposed over nanoparticles.
