Canon has developed a new QD-OLED material: replacing rare earth metals with lead, reducing costs by 99%

On May 29th, IT Home reported that Canon has developed an organic light-emitting diode (OLED) panel material that does not use rare earth metals and plans to commercialize the technology within a few years, according to Nikkei News.
This new material is quantum dot QD-OLED, which is a small semiconductor particle with a diameter of 1 nanometer. When illuminated or injected with current, particles will emit bright colors.
Other quantum dot displays have been used in high-end OLED televisions, but they cannot escape rare metals, such as the compound indium phosphide used by Samsung Electronics. (IT Home Note: Indium is a rare metal with minimal production, mainly produced in China.)
According to the report, Canon's new QD-OLED material will replace indium phosphide with lead, which is easily obtained from recycled raw materials in "urban mines". Canon's goal is to commercialize this material by establishing large-scale production technologies by the mid-2020s (around 2025).
Although the performance of lead is not as good as that of indium, Canon has designed a compound that is claimed to be as durable as indium phosphide by utilizing its expertise in composite materials such as office equipment carbon powder and ink. The material cost is expected to be reduced to one percent of that of Samsung QD-OLED.
