OLED displays are garnering attention for use in such mobile devices as digital cameras. These self-emitting displays are based on the phenomenon of organic electroluminescence, which occurs when voltage is applied to excite organic materials sandwiched between two electrodes. When the materials revert to their original state after being excited, they release energy as light. Because they are self-emitting, these displays are remarkably bright and unlike liquid crystal displays, offer a wide angle of view. Additionally, the technology features fast response speeds and emits light while generating virtually no heat, ensuring low power consumption and making them ideally suited for use in mobile devices.

Leveraging photosensitive-material technologies for electrophotographic devices, Canon has developed original RGB light-emitting materials and carrier-injection materials for OLED displays, achieving levels of efficiency and color purity among the highest in the industry.

The top emission structure of OLED displays, a structure designed to convey light to the top of the emission layer, also provides a large NA, achieving high luminance, low power consumption, and prolonged life. Canon is currently devoting its energies to the development of device and process technologies for commercialization in the near future. The company aims to mass produce high-performance OLED elements at a low cost to achieve advanced functionality in mobile devices.
