Canon introduces next-gen perovskite quantum-dot inks for OLED displays

Canon Inc. has announced the development of a quantum-dot ink with a perovskite structure (‘perovskite quantum-dot ink’) with the potential to help realize next-generation OLED displays with ultra-high definition, such as quantum-dot 8K displays, a technology that thus far has been unachievable. The performance and image quality of display devices continue to rapidly improve, and towards this end, one such approach that is gaining momentum is applying quantum-dot technologies (QD) to meet the need for displays with higher image quality,” Canon said.

Quantum dots are semiconductor nanocrystals that measure only a few nanometers in diameter and can emit light with high brightness and high colour purity. Displays with quantum-dot technology are attracting growing attention due to their wide colour gamut that makes possible high visual expressiveness. To address the issue of durability, Canon is leveraging its proprietary technologies nurtured through development of ink and toner. The company has established a unique method to form a protective shell on quantum dots, thereby achieving practically durable perovskite-dot ink with retained colour purity and light usage efficiency. Canon’s quantum-dot inks have the potential to help realize next-generation OLED displays with ultra-high definition, such as quantum-dot 8K displays, a technology that thus far has been unachievable.
