Kuntech (officially Shaanxi Kuntech Semiconductor Technology) was established in 2018 in Xian, Shaanxi, China with an aim to become an AMOLED producer.
Taiwan's AUO (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 the world's number 3 manufacturer of TFT-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 maker, producing both LCDs and OLEDs. BOE also produces LCD backlighting units and solar panels.
BOE has a 5.5-Gen LTPS fab in Ordos that produces LCDs, and was also meant to produce OLED displays but it's not clear if the fab is actually in production. BOE started to produce flexible OLED displays at its Chengdu B7 6-Gen fab in October 2017.
China Star Optoelectronics Technology (CSOT, also called Shenzhen Huaxing Photoelectric Technology) is a China based display producer (owned by TCL, Century Science & Technology Investment and Samsung Display). The company is producing small and large LCD panels and is developing OLED technologies.
In March 2012 it was reported that the company plans to enter the AMOLED market. The original plan was to start production by the end of 2012 in a 4.5-Gen LTPS line, but that never materialized. In October 2012 AUO filed a law suit against two of its former executives that allegedly stole technologies (including AMOLED related ones) from the company and supplied it to CSOT.
CPT (Chunghwa Picture Tubes) was established in 1971 in Taiwan and is a maker of LCD and CRT displays.
In June 2012 it was reported that the company has started developing AMOLED panels and has a small-size experimental line. CPT is currently producing AMOLEDs in low volume, and is also reportedly aiming to mass produce flexible OLEDs in the future.
EverDisplay Optronics (also known as Hehui Optoelectroics) established in Shanghai, China in October 2012 aims to establish China's first AMOLED LTPS production facility.
Everdisplay started mass producing 5" 720p AMOLED displays towards the end of 2014 in a 4.5-Gen line with a monthly capacity of 20,000 substrates. Since then the company added more displays - wearable panels and larger 5.5" ones. Everdisplay is also developing flexible panels, transparent panels and high-density AMOLEDs for VR applications. According to reports, Xiaomi's Redmi Pro smartphone uses EDO's (and BOE's) 5.5" FHD AMOLED panels.
New Vision Optoelectronic was established in August 2010 in Guangzhou with an aim to become an AMOLED producer. The company is collaborating with the South China University of Technology (SCUT) and is a wholly-owned subsidiary of Skyworth.
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” and 4”) AMOLED displays but had some technical difficulties.
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". JDI requires around $1.7 billion to start OLED production, and is now raising the funds needed - looking for partners in Japan and China.
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 received an investment from the Innovation Network Corporation of Japan, a public-private investment fund, which still holds the majority sake, with JDI, Sony and Panasonic holding smaller stakes.
