Samsung Display, the world's largest display maker was spun off from Samsung Electronics in April 2012. In July 2012 Samsung Mobile Display was merged into Samsung Display, which maintains two display units: OLED and LCD.

Samsung Display is the world's largest OLED producer. You can read more about Samsung's OLED products here.

TCL 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.

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.

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".

OLiGHTEK (also known as the Yunnan North OLiGHTEK Opto-Electronic Technology Co), established in 2011, is a Chinese based company that develops and produces OLED microdisplays.

In 2017 OLiGHTEK announced a joint-venture with BOE Technology to establish a $170 million OLED microdisplay fab in Kunming, China. The fab is now under construction and according to reports trial production will begin in 2019.

For more information on OLiGHTEK's OLED microdisplay - and the entire OLED microdisplay market, check out our OLED Microdisplays Market Report.

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.

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

Sichaun CCO Display Technology was established in 2008 in Chengdu, China by Changhong Electronics group and Chengdu Hi-Tech Investment Group.

Sichuan CCO produces PMOLED displays and has an annual capacity of 12 million 1-inch displays. The company's PMOLED displays range from 0.7" monochrome to 2.5" full color.

In 2013 the company shifted its focus to AMOLED panels, and in June 2013 the company announced plans to build a 4.5-Gen AMOLED fab by 2016. There were no updates on this plan since.

WiseChip Semiconductor Inc (WSI) was established in 2005 in Taiwan. The company develops and produces PMOLED displays. In 2009 WiseChip acquired fellow PMOLED maker Univision.

Wisechip says it's the world's second largest PMOLED maker, and the company now enjoys a surge in PMOLED demand (we hear the same from other PMOLED makers). The company currently offers glass-based PMOLEDs ranging from 0.33" to 5.5".

In May 2020 we posted an interview with Wisechip's VP of R&D.

Nippon Seiki was established in 1946 in Japan and is making and selling instruments for automobiles and office automation appliances.
