Sumitomo Chemical's Polymer OLED Lighting

Technology Advantages

  • Facile color tuning using a single emitter layer
  • Simple structure leads to better productivity
  • Processable solution: cost-effective technology
  • Ultra-thin lighting tiles giving natural light
  • Low power consumption: reduces environmental impact of lighting

We believe that polymer OLED lighting can create new value in the future by shedding completely new light on life with energy efficiency and comfort.

Comparison of PLEDs and SMOLEDs

Because PLED lighting is formed by a single emissive layer, it entails a simpler production process and lower production costs compared to SMOLEDs.

Compared with small molecule organic LED (SMOLED), PLED technology has great potential to enable more cost-effective production of lighting panels because of its simpler production process.
Sumitomo Chemical is developing PLED lighting technology. Our technology enables a light-emitting layer to be formed by a single printing. With printable PLEDs, production costs will be lower and larger lighting panels will be easily produced.

Future Prospects


Flexible lighting

  • Further power reduction for general lighting applications
  • Polymer OLED (Organic Light Emitting Diode) on plastic substrates delivers the following advantages:
    • Low cost of production
    • Lightweight
    • Flexible
    • Robust


Development Plan

We are aiming to develop PLEDs for design lighting applications by 2013 and for general lighting by 2015. We are developing PLEDs with plastic substrates with the aim of commercialization by 2015.
