- Abstract
- Top-emitting arrays of organic light-emitting diodes (OLEDs) have been fabricated and demonstrated on complementary metal-oxide-silicon (CMOS) circuitry. The 8x8 array of OLEDs is composed of 90 mu m micropixels with a 55 mu m separation. The OLEDs are based on an emitting layer of tris-(8-hydroxyquinoline)aluminum (Alq(3)) doped with coumarin 6 to provide green light emission. A layer of N,N'-diphenyl-N, N'-bis(3-methylphenyl)1-1'-biphenyl 1-4, 4'-diamine (TPD) was used as a hole transport layer and poly(ethylenedioxythiophene) doped with polystyrenesulfonate was used as a buffer layer between the TPD and the CMOS anode metal. Bright light was emitted through a semitransparent Mg:Ag cathode when the micropixel was driven by an individual current source. (C) 2000 American Institute of Physics. [S0003-6951(00)02126-4].
