This is the first mass production of OLED displays by printing. It differs from the conventional vapor deposition method. JOLED will produce 10- to 32-inch, medium-sized high-performance and high-quality OLED displays under the OLEDIOTM brand, for high-end monitors, medical monitors, automotive displays, and so on.
There are numerous advantages to printing OLEDs, but it has proved to be challenging. JOLED is producing OLED displays using the proprietary TRIPRINTTM technology that forms an EL layer by printing RGB EL materials. While the printing method requires advanced technical capabilities, it is expected to represent a major innovation in OLED display production, because its production process is simple and efficient, and it is adapted for medium- to large-sized OLED production, which is difficult using the conventional RGB vapor deposition method.
JOLED has been carrying out R&D of printed OLED and started production in the pilot line in 2017. It started operation of mass production line in 2019 and has been making trial products. JOLED now will move from trial to mass production and aim at expansion of sales.
“We are so delighted to ship our brand-new OLED display OLEDIO from the world’s first printed OLED mass production line, which is full of our technology and expertise,” said Tadashi Ishibashi, representative director and president of JOLED. “I am filled with deep emotion when I reflect upon our journey from the establishment as a R&D company to today, overcoming several challenges, and finally reaching mass production. We will produce high-performance and high-quality OLED displays using the groundbreaking printing method and will provide innovations to the medium-sized category in the world OLED market.”
