Taiwan's AUO Corporation (previously known as AU Optronics) was formed in 2001, by the merger of Acer Display and Unipac Optoelectronics. Later in 2006 AUO merged with Quanta Display. AUO is one of the world's largest producers of LCDs.
In 2006 AUO became the world's first AMOLED producer but in 2007 the company decided to shift focus back to LCD, and stopped investing in OLEDs.
BOE Display, founded in 1993 in Beijing China, is one of the world's leading display makers, producing both LCDs and OLEDs. BOE also produces LCD backlighting units and solar panels.
BOE has been producing small glass-based OLEDs for some time, but the company's focus is currently in flexible and foldable OLEDs. In October 2017 BOE started to produce flexible OLED displays at its first flexible OLED line, the Chengdu B7 6-Gen fab. The annual capacity of the B7 line, when complete and at 100% yields, will be 45,000 monthly 6-Gen substrates, or about 90 million smartphone OLEDs.
EverDisplay Optronics (also known as Hehui Optoelectroics, and EDO), established in Shanghai, China in 2012, is an AMOLED display producer.
Everdisplay started mass producing AMOLED displays towards the end of 2014 in a 4.5-Gen line with a monthly capacity of 20,000 substrates (EDO was China's first AMOLED maker). Since then the company added its second production fab, a 6-Gen flexible AMOLED line in Shanghai.
EDO is producing panels for wearables, smartphones, laptops, VR devices and more. Many of EDO's displays are available in the OLED marketplace.
In 2021, Everdisplay became a public company.
HKC, established in 2001 in Shenzhen, China, is an LCD producer that has three LCD production sites in Chongqing, Chuzhou and Mianyang. The company is one of the world's largest LCD makers, with an estimated market share of around 10% from the global TV panel market, and around 6.5% of the global display industry as a whole.
HKC aims to become an AMOLED producer. In 2023, it started a collaboration with JDI to build an eLEAP AMOLED production line in China. These plans were canceled though towards the end of 2023. The company continued to develop its AMOLED technologies, and in early 2025 it acquired Royole's AMOLED production line equipment.
In July 2025 HKC produced its first AMOLED display sample - a smartphone type panel, produced on an advanced Oxide-TFT (IGZO) backplane.
Innolux was established in 2009 in Taiwan as a merger between Innolux, CMO and TPO. Both TPO and CMO had OLED subsidiaries. The company was known as Chimei Innolux up until October 2012 when it decided to change its name back to Innolux.
CMO's OLED subsidiary was called Chi Mei EL Corporation (CMEL) and was producing AMOLED displays until the merger (the company was producing panels up to 7.6" in size). TPO was developing small (3-4 inch) AMOLED displays but did not reach mass production and faced technical difficulties.
INT Tech, established in 2016 in Taiwan, developed advanced technologies for the display industry. INT Tech is a public company that went public in Taiwan at the end of 2018.
INT is developing an ultra-high pixel density OLED display (UHPD) and truly-flexible sensor (SPIC) technologies. The company has a production line in Taiwan, and is constructing a production line in China (owned by its subsidiary KT&T).
In January 2020 INT Tech produced its first prototype display - a 0.7" 2,300 PPI real RGB side-by-side AMOLED display. In April 2020 INT Tech signed an agreement to establish a $143 million OLED display fab in the city of Taizhou in Zhejiang province, China (via KT&T).
In 2025, INT Tech unveiled the world's highest brightness full-color OLED microdisplay at 60,000 nits, and later in the year followed with a 100,000 nits microdisplay.
Japan Display (JDI) is a display producer, formed in 2011 in Japan by the merger of Sony's, Toshiba's and Hitachi's display businesses and funded by Japan's government fund Innovation Network Corporation (INCJ).
JDI was late to the OLED industry, and in 2017 JDI 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". The company however didn't achieve mass production of displays beyond small wearable AMOLEDs (which it supplied to Apple). In 2025, the company stopped its OLED production as it could not compete with larger scale producers.
In 2022, JDI announced a maskless OLED deposition process which they refer to as eLEAP. JDI is focused on that technology, but it has yet to initiate production.
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.
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.
Royole was established in 2012 to develop novel display technologies and IP. Royole built a $1.7 billion 5.5-Gen (45,000 monthly substrates) flexible AMOLED production facility in Shenzhen, China, and was mostly focused on novel flexible OLED production, although it also developed a VR headset (the Royole Moon), sensor platform, ePaper-based products and more.
Royole was backed by several Banks and VC funds and had offices in California US and Shenzhen, China. In September 2017 Royole raised $800 million in its fourth financing round.
In 2022 Royole faced financial problems, failing to secure large customers for its OLED panels. In 2023, the company went out of business. Its production equipment was later sold to HKC.
