The Nikkei reports that JOLED aims to start producing prototype OLED panels in the second half of 2017. JOLED developed a 21.6" UHD panel and actually aims to start offering the panel in 2017 to medical monitor makers and other commercial applications.
JOLED is using a printing based process and it is estimated that production costs will be 30% to 40% lower than evaporation based processes - but the performance of soluble OLED materials are not yet up to par with evaporation materials. The panels are made on an Oxide-TFT backplane, and the process is optimized for 10 to 30 inch panels. JOLED expects to achieve mass production in FY2018 (April 2018 to March 2019).
In April 2016 we reported that JOLED developed OLED panels, a 12.2" FHD (180 PPI) panel and a 19.3" 4K one (230 PPI). JOLED is preparing a Gen-4.5 fab, and investments in its R&D and pilot production facility are expected to reach $160 million.
In early 2016 it was reported that Japan Display (JDI) aims to acquire JOLED, but that did not materialize, at least yet. JDI was interested in Sharp's LCD division, originally, but Sharp finally decided to sell out to Foxconn. In 2015, it was reported that JOLED is in talks with Apple for a possible supply agreement for Apple's future iPad devices.
