Starting next year, the Chinese display specialist China Star Optoelectronics (CSOT) plans to build its first factory for the mass production of OLED displays, in which the panels will be manufactured in a novel way - like an inkjet printer.
As reported by the Taiwanese industry service DigiTimes, CSOT plans to begin construction of a so-called 8.5G factory in the city of Guanghzou in southeast China in 2021. The company plans to produce the first OLED panels using inkjet printing there within a few years. Mass production at the new plant is said to be targeted for 2024.
Technology (almost) ready for mass production
CSOT has been working under high pressure for several years on the production of OLED panels using inkjet printing. The company has already made significant advances in the technology, which includes the actual manufacturing process, but also the production of the carrier layers required for the panels.
It has also developed new materials to ensure that OLED displays produced by inkjet manufacturing are capable of displaying the widest possible color space. CSOT, which is part of the ecosystem surrounding the Chinese television and smartphone manufacturer TCL, plans to invest the equivalent of around $6.8 billion in its first factory for project-printed OLED displays.
Although the new technology promises to make OLED displays cheaper to produce, it does not achieve the same high pixel densities as are common in displays for smartphones and other compact electronic devices. Instead, the panels produced by inkjet printing are likely to be used primarily in televisions and other large-format devices. TCL had already shown first prototypes of this type.
