Canon develops OLED panel materials that do not rely on rare earth metals, ushering in a new era

News on May 29, according to the editor's understanding, Canon has recently developed a new organic light-emitting diode (OLED) panel material that does not rely on rare earth metals and is expected to be commercialized in the next few years.

The new material composed of tiny semiconductor particles with a diameter of 1 nanometer is called quantum dot QD-OLED. When light shines on it or an electric current is injected into it, these tiny particles emit bright, vivid colors.

There have been other quantum dot displays used in high-end OLED TVs before, but they still relied on rare metals, such as the compound phosphorus used by Samsung Electronics Indium (indium is a rare metal with very limited production and its main origin is China).

According to reports, Canon’s new QD-OLED material will use lead instead of indium phosphide, and lead can be easily obtained from recycled raw materials in “urban mines”. Canon aims to commercialize the material around 2025 by establishing mass production technology.

While lead doesn’t perform as well as indium, Canon used its expertise in composite materials such as office equipment toner and ink to design a product called Indium Phosphide. Same durable compound. The cost of the material is expected to be reduced to one percent of Samsung's QD-OLED.

This breakthrough by Canon will have a major impact in the field of OLED technology. The application of this technology can not only reduce the demand for rare earth metals, but also is expected to reduce material costs, improve production efficiency, and accelerate the development of OLED displays. This technological advancement is significant for companies that make consumer electronics products such as televisions and mobile phones.

With Canon’s breakthrough in QD-OLED materials, we can expect more high-quality OLED display products that do not rely on rare earth metals to appear on the market in the near future . This will bring more choices to consumers and further promote innovative development of display technology.
