[6][7][8] On August 31, 2011, Sony, Toshiba, and Hitachi agreed to a merger of their respective small-to-medium-sized LCD businesses, supported by an investment of two hundred billion yen from INCJ.

[11][12] JDI had accumulated consecutive losses since its IPO, a restructuring plan was announced in 2017, including closing down a production line in Japan and layoffs of approximately a third of its workforce.

[17] The Hakusan plant was built in 2015 and began operations in 2016 at a cost of US$1.5 billion, and has been partly idle since June 2019, due to Apple's use of OLED displays.

[18] In July 2020, the CEO of JDI revealed the company's plan to start mass production of OLED display panels for smartphones "as early as 2022" with a novel manufacturing technology, adding that it would require new funding.

The company has developed an improvement for darker black pixels (true-black appearance), called "IPS-NEO", which reduces the light shining through from the backlighting.

[26][27] For reflective LCDs without backlighting, JDI has developed an addressing technique using a thin-film memory device SRAM in addition to the conventional TFT for each pixel, so that a still image can be stored consuming a low amount of energy.

[29] In December 2019, it announced that it has developed a 1.6-inch microLED display module with a pixel density of 265 ppi and a peak brightness of 3,000 nits, which can be assembled to form a large screen.
