OLED display producers

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.

In January 2008 AUO resumed their OLED operation, and after years of development the company started mass producing AMOLEDs again in 2014. AUO is also developing OLED TV panels, flexible and bendable panels, transparent OLEDs and OLED lighting panels. The company's OLED program is mainly focused on wearable OLEDs and OLED for VR applications.

BCDTEK (also known as Shenzhen Xinshijia Semiconductor Technology) develops OLED ICs and OLED microdisplays.

IN 2022, BCDTEK announced it is building a $970 million 12-inch OLED microdisplay fab.

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 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

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 both LCDs and OLED displays.

CSoT started developing OLED technologies back in 2012. In 2013 it was reported that CSOT will invest over $4 billion to build a 8.5-Gen Oxide-TFT LCD+OLED TV fab, but that did not materialize. In 2017 CSoT started to construct a 6-Gen LTPS flexible AMOLED production line in Wuhan, China, in a $5.08 billion investment. CSoT is now producing mobile AMOLED displays at that fab, and is developing high-end technologies, including LTPO, microlens arrays and polarizer-free OLEDs.

Dresden Microdisplay was established in April 2010 as a spin-off from the Fraunhofer Institute with an aim to commercialize the Fraunhofer's OLED microdisplay technology.

Currently Dresden Microdisplay offers a single OLED microdisplay, the low power QVGA SVPO320. The company also offers bidirectional microdisplay samples.

eMagin is engaged in the design, development, manufacturing and marketing of OLED microdisplays. eMagin's traditional markets are the defense and industry ones, but the company is also targeting the consumer VR and AR markets with its latest microdisplays. eMagin is a public company (NYSE AMERICAN:EMAN).

eMagin is developing high-end OLED microdisplays, and in early 2017 started shipping 2k x 2k displays. eMagin is also developing direct-emission OLED microdisplays.

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.

Futaba Corporation is a Japanese company that produces Vacuum Fluorescent Displays (VFDs) and other industrial and commercial components and modules. In October 2011 Futaba bought TDK's part in their PMOLED joint venture, TDK Micro Device Corporation, which is now a Futaba subsidiary.

Futaba develops and manufactures small PMOLED displays for consumer applications including flexible PMOLEDs.

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.

The company has setup a small pilot line capable of producing 5" to 7" Oxide-TFT AMOLED panels (including transparent ones and embedded touch panels).

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".

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.

Kuntech (officially Shaanxi Kuntech Semiconductor Technology) was established in 2018 in Xian, Shaanxi, China with an aim to become an AMOLED producer.
