Panasonic Corp said on Thursday there are partnered an associate of Japan Display to license out a low-cost organic light-emitting diode (OLED) panel-making process, a likely solution to the regular method used by dominant South Korean manufacturers.

The unlisted affiliate, JOLED, is at talks with several global panel producers to license its printing process for OLED panels, where organic colour materials are deposited onto glass substrates in many ways much like ink-jet printing.

The method can produce OLED screens 20 percent to 30 percent less expensive than the present evaporation process simply because it does not need equipment which include vacuum chambers or metal masks to deposit large materials, depending on JOLED.

Panasonic will design and develop printing equipment, while a unit of panel and chip-making equipment manufacturer Screen Holdings Co will be liable for actual output of the apparatus and maintenance.

JOLED, created in 2019 by merging the OLED divisions of Panasonic and Sony Corp, also promises to start mass production of smaller panels alone in 2020.

To finance the assembly plan, JOLED raised JPY 47 billion ($425 million) in June through the sale of new shares to auto parts maker Denso Corp and three other Japanese firms, JOLED said separately on Thursday.

Smartphone makers are actually increasingly shifting to OLED, with Apple Inc adopting them for their latest iPhone X, as OLED screens are often thinner and might show more vivid colours than lcd (LCD) panels.

Japanese manufacturers began investing in OLED technology from the 1990s, led by Sony and Pioneer Corp. Most lost because of expense and defect rates, allowing South Korea’s Samsung Electronics Co and LG Display Co to consider lead.
