Lextar

Lextar logoEstablished in 2008 in Taiwan as a subsidiary of AU Optronics, Lextar Electronics Corporation is a leading LED developer. Lextar produces LED chips, LCD backlights, automotive LEDs, lumiaires and other lighting solutions.

In 2018 Lextar introduced its first micro-LED chips - both RGB ones and color conversion ones, both suitable for mass transfer processes.

Nichia

Nichia logoJapan-based Nichia Corporation is a leading chemical engineering and manufacturing company that produces LEDs, laser diodes, battery materials and more.

Nichia develops micro-LED chips, transfer technologies and related equipment.

Epileds Technologies

Epileds logoTaiwan-based Epileds Technologies was established in 2006 at the Tainan Science Park. Epileds develops, designs and produces blue, green, red, and white light LED wafers and chips.

In early 2018 it was reported that Epileds has initiated an R&D project to develop micro-LEDs and mini-LEDs. In May 2018 Foxconn acquired a stake in Epileds, with a specific interest in its micro-LED project.

Changelight

Changelight logoEstablished in 2006, China-based Changelight is a manufacturer of LED devices, mostly for outdoor applications.

In 2018 it was reported that Changelight is developing both mini-LEDs and micro-LEDs. For micro-LED displays, Changelight focuses on chip and mass transfer technologies.

San'an Optoelectronics

San'an Optoelectronics logoSan’an Optoelectronics is China's largest LED epitaxial wafers and chips producer. San'an says it produces over 24 million epitaxial wafers and 300 billion LED chips annually - which is about 58% of the total production in China.

In 2018 San'an signed a long-term agreement with Samsung to co-develop and supply LED chips for Samsung's Micro-LED displays.

Aledia

Aledia logoFrance-based Aledia, founded in 2011, developed a technology to grow 3D GaN LEDs on 200 mm and 300 mm silicon wafers using CMOS wafer-fabrication processes and tools. Aledia says that its LED chips are 25% cheaper compared to traditional planar LED chips, and these LEDs can be used for micro-LED displays.

Aledia raised over $40 million in two financing rounds in 2013 and 2015 and $36 million in its Round C financing round in 2018. In 2020 Aledia announced that it plans to establish a 140 million euros LED production fab. The company raised 80 million Euros towards the new plant in 2020, and in 2022 announced a $30 million line of credit.

Glo

Established in 2003 in the USA (with operations in Sweden as well) based on research performed at Lund University, Glo is developing GaN nanowire based micro LEDs for display applications. In 2021 the company was acquired by Nanosys.

Glo says that its Nanowires enable red, green and blue microLEDs with the reliability of an inorganic materials system. Glo is targeting the entire display market, from small-sized wearable displays to TV panels and large-area displays and can use its microLEDs on both CMOS and LTPS backplanes. Glo is a fabless operation - it has an manufacturing agreement with one of the world's largest LED makers to produce its microLED chips and it has also signed an agreement with one of the world's largest display makers to produce the actual MicroLED panels.

PlayNitride

PlayNitride logoTaiwan-based PlayNitride was established in June 2014 to research and develop Nitride related materials and applications. The fabless company is now focusing on GaN based MicroLEDs.

PlayNitride developed its own microLED epiwafer production process (using Aixtron’s G5+ MOCVD systems), its own stamp-based transfer technology and also its own repair technology (SMAR.Tech).

PlayNitride is developing wearable passive-matrix PMOLEDs in a joint-venture with affiliate RiTDisplay. The company also developed a technology branded as PixeLED Matrix, which is a tiled microLED display module for TVs and signage.

Epistar

Epistar logoEpistar Corp, based in Taiwan and established in 1996, is one of the world's largest LED producers. The company specializes in high-brightness LED devices for general lighting and consumer electronics.

Epistar is developing Micro LED chips but has yet to announce any products or market intentions. Some reports suggest the Epistar is likely to first produce 100-micron LEDs (in 2017) to be used in large displays. This will be followed by smaller LEDs for smaller displays.
