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.

Application

  • Roll-to-roll mass production

OLED lighting has great potential as a lightweight and large-area diffused light source. The global market of OLED lighting is thriving and its application in generic lighting is also moving forward. We have been developing materials and manufacturing technology for low cost and high efficiency for large-area OLED lightings .

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 OLED (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.

Features of Sumitomo's OLED Lighting

We are also developing light-emitting materials focusing on improving efficiency, lifetime, power consumption and color rendering properties to achieve flexible OLED lighting. We developed a low-cost device structure using plastic substrate and non-ITO cathodes, a scalable roll-to-roll process technology to apply and dry inline, inkjet printing, and slot die printing technology as a printing method. We are also studying high efficiency technology by improving light extraction.
