Canon QD-OLED

2023: Product Announcement

On May 26, 2023, it became known that Canon had developed a new method for producing QD-OLED displays, which reduces the cost of such products by two orders of magnitude.

QD-OLED panels combine quantum dot (QD) technology with organic LEDs (OLEDs). Compared to conventional LCD screens, OLED displays have higher contrast and improved color reproduction. In addition, in the case of OLED, backlight is not required, since organic LEDs emit light on their own. At the same time, the addition of quantum dots allows you to accurately control the luminance of each pixel, as well as solve the problem of OLED burnout.

Canon has developed a new QD-OLED display manufacturing technique

QD-OLED is the most advanced display technology. But such products are very expensive, since only Samsung is engaged in their production, and the manufacturing process provides for the use of rare earth metals, in particular, India. Canon specialists managed to find an alternative approach: to replace India, the extraction of which is concentrated mainly in China, it is proposed to use widely available lead.

It is reported that Canon engineers were able to solve the problem of low lead efficiency when used as part of quantum dots. As a result, this metal can be used instead of expensive indium in QD-OLED displays. The financial cost of using Canon technology may be about 100 times less than Samsung's approach. In addition, there is no need to purchase India from China, which ensures technological independence. Once commercialised, Canon's achievement could see prices for premium-class TVs plummet. Mass production of panels of a new type is planned to be organized in the mid-2020s.^[1]
