Canon has developed a new method for manufacturing screens with QD-OLED technology, as announced by the Japanese giant last week. The new way of production eliminates the use of rare materialswhich could make components cheaper.
Although Samsung is at the forefront of supplying QD-OLED panels, its production technique requires rare metals — such as the chemical element indium (In), found mainly in China — which make the manufacturing process very costly, making the products with this technology are more expensive for consumers.
Proposing a more accessible form of production, Canon is working on a method that dispenses with the use of these precious metals to ensure a more stable chain free of geopolitical conflicts. For this, the manufacturer replaces indium compound with leada much more frequent, reusable and inexpensive metal.
Lead, on the other hand, has some disadvantages compared to indium. According to a report by the Nikkei Asiaone of the concerns was the durability of the cheaper metal in continuously active panels, but the manufacturer claims to have developed a composite as durable as the material used by Samsung.
The indium compound covers 88% of the color gamut based on ITU-R BT technical recommendations. 2020, while Canon’s technology can cover up to 94% of the range. Furthermore, the high efficiency of using light is expected to reduce the energy consumption of quantum dots by approximately 20% compared to conventional technology.

Canon did not reveal other details about what strategies it intends to adopt to market these products, but it is possible that this is its main pillar to gain space in the industry of monitors and televisions.
QD-OLED a evoluo do OLED
LG revolutionized the television market with the development of light emitting diodes (OLED), which dispenses with the use of a continuously illuminated panel to emit light. With this technology, each point of the screen is individually illuminated to ensure the best black color depth and excellent contrast ratio.
After about a decade, Samsung introduced Quantum Dot OLED (QD-OLED). This invention stands out for using quantum dots — that is, semiconductor nanoparticles that emit light — which guarantee superior brightness and greater color fidelity than OLED.
Televisions with Samsung’s QD-OLED technology are still limited in availability and prohibitively expensive. The Samsung S95B, for example, is available in European countries with suggested prices starting at €2,500 (about R$13,570) for the 55-inch version.
