Aledia

Aledia logoFrance-based Aledia, founded in 2011, developed a technology to grow 3D GaN LEDs on 200 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.

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.

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.

Epistar

Epistar logoEpistar Corp, based in Taiwan and established in 1996, is one of the world's largest LED producer. 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.

Glo

Glo logoEstabilshed in 2010 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.

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.

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.

Micro Nitride

Japan-based Micro Nitride was established in 2018 as a subsidiary of Nitride Semiconductors to develop micro UV LED chips for Micro-LED displays.

Micro Nitride's technology, called μUV-LED+RGB phosphor, uses UV micro-LEDs and RGB phosphors.
