Japan Display (JDI) is a small/medium display maker, formed in September 2011 by the merger of Sony's, Toshiba's and Hitachi's display businesses and funded by Japan's government fund Innovation Network Corporation (INCJ), which holds 70% of the shares.
JDI considers OLEDs to be the core technology of the next generation small size and medium size displays, and in 2017 the company announced that it is going to perform a "last-chance" restructuring to focus on OLEDs as there is "no future for the smartphone panel business without OLED".
In August 2014 JDI, together with Sony, Panasonic and INCJ, launched JOLED to develop and produce printed OLED panels. In December 2016 JDI raised $635 million from INCJ to increase its stake at JOLED, and in 2020 the company raised $935 million from Ichigo. In October 2019 Japan Display announced it has started to produce OLED displays - likely indeed this is low volume production for Apple's wearables. In 2023 JOLED filed for bankruptcy, and JDI took over all of its assets.
In 2022, JDI announced a new OLED deposition process which they refer to as eLEAP, that the company says is a breakthrough OLED production process. The company seems now focused on commercializing this technology, and in early 2023 it signed an agreement with HKC to start mass production of eLEAP OLED displays by 2025.
