OLED materials
Our OLED materials are used primarily in the key three layers of light-emitting panels (μOLED*2) in the EVF*1 in Canon cameras: the hole transport layer, emission layer, and electron transport layer. High-mix, low-volume production allows us to supply a diverse range of OLED materials at commercial scale, tailored to different needs, properties, and applications.

- *2 OLED：Organic Light Emitting Diode
Introducing the Principle
In an OLED, when a voltage is applied, holes are injected from the anode and electrons from the cathode, and light is emitted when the holes and electrons recombine in the emission layer. Organic electronic materials are used in each layer of the OLED.
Production Process and Features
To be able to synthesize OLED materials, which require high purity, we employ the following production process.
Our OLED Material Production Strengths
- Can handle end-to-end production from synthesis to sublimation purification, with extensive experience in multi-step synthesis
- Quality pre-screening of key raw materials to prevent production issues
- Can achieve the high levels of purity required for organic semiconductors
- Sublimation purification enables the removal of solvent and metal components
