Presentation Summary

  • VTT develops ultra-thin, printed Organic Light Emitting Diodes (OLED) for displaying dynamic signage icons, characters or numerals on flexible planar surfaces.
  • The realization of this novel signage technology is based on three enabling platforms: polymer light-emitting materials, printing deposition methods and roll-to-roll processing techniques.
  • We present the end applications of printed OLED technology in RFID field. RFID driven smart poster with the OLED as RFID tag indicator, RFID driven seven segment OLED display and RFID driven smart package with 2 colour OLED indicator will be presented.
