JOLED (Japan OLED) was established in August 2014 by Japan Display, Sony and Panasonic with an aim to become an OLED medium display producer (focusing at first on OLEDs for tablets, monitors, laptops and signage).
JOLED Is using an ink-jet printing process, which (according to the company) enables it to produce at a lower cost - around 30-50% cheaper compared to evaporation. JOLED is using Sumitomo's P-OLED materials.
US-based Kopin Corporation is a developer of microdisplays and other components for wearable devices.
In December 2016 Kopin announced it is developing OLED microdisplays, and the company since introduced several OLED microdisplays (the first ones were 1" 2Kx2K and 0.49" 1280x720) and announced several design wins.
Kopin signed agreements with OLiGHTEK and with BOE's JV with OLiGHTEK for the production of its OLED microdisplays, but later started working with Lakaeside Optoelectronics.
In early 2023 Kopin spun-off its OLED business unit to Lightning Silicon Technology.
KT&T was established in 2020 as a spin-off from INT Tech, to commercialize its OLED microdisplay technology, following INT Tech's $143 million OLED fab in the city of Taizhou in Zhejiang province, China.
In 2022, KT&T introduced its first microdisplays, based on its own UNEEDXR technology that enables ultra-high pixel densities on either TFT or silicon backplanes. The company's technology is based on RGB structure, without color filters, to achieve high brightness (up to 12,000 nits) and low power consumption.
Following several rounds of investments, KT&T became an independent company, and INT Tech is still a major shareholder.
Kuntech (officially Shaanxi Kuntech Semiconductor Technology) was established in 2018 in Xian, Shaanxi, China with an aim to become an AMOLED producer.
The company has setup an AMOLED R&D center, researching different flexible AMOLED technologies, and has plans to build a $6 billion 6-Gen flexible AMOLED production line by 2021.
Kunshan Mengxian Electric (also known as Qingyue Optical) was established in 2020 in China with plans to produce OLED microdisplays. The company is owned by Qingyue, a PMOLED producer that was spun-off in 2021 from OLED maker Visionox.
In 2020, Kunshan Mengxian announced its plans for a $55 million OLED microdisplay line, in Kunshan, Jiangsu province. The company is looking to produce direct-emission RGB OLED microdisplays.
Lakeside Lightning Semiconductor (LLS, also called Lakeside Optoelectronics) was established in April 2017, in Changzhou, Jiangsu, China. The company develops and produces OLED microdisplays.
LLS operates a small 8-inch production line in Changzhou, and is building an advanced 12-inch OLED microdisplay fab in Yixing (Wuxi). Lakeside is collaborating with US-based Lightning Silicon Technology (Kopin).
LG Display, based in Korea, is one of the world's largest display makers. LGD produces screens for TVs, laptops and mobile devices, focusing on OLED technologies.
LG Display is the world's leading OLED TV and monitor panel producer (based on its WOLED architecture). The company also produces flexible AMOLEDs for wearables, tablets and smartphones (branded as pOLEDs, and supplied to many companies including Apple). LG Display is also offering automotive OLED displays, transparent OLEDs, and is developing OLED microdisplays.
Lightning Silicon Technology was established in early 2023 as a semi-spin-off from Kopin, to develop and supply advanced OLED microdisplays to consumer AR and VR markets. The company licensed Kopin's technology. Kopin holds 20% in Lightning Silicon.
Lightning Silicon is a fabless company and has an agreement with China-based Lakeside Lightning Semiconductor.
Established in Shanghai, China in 2016, Lumicore develops display ICs and also produces OLED microdisplays. In 2021 the company started to construct a 8-inch OLED microdisplay production line in Nanjing. The low-volume line is now capable of mass production.
In early 2024, Lumicore announced it has raised $100 million in its Series A funding round. The company announced several microdisplay products.
Metaways (also called Zhejiang Hongxi Technology) is an OLED microdisplay producer based in China.
