MicroLED display developers

Leyard Optoelectronics

Leyard logoChina-based Leyard Optoelectronic, established in 1995, produces LED based products, including displays and lighting. The company's main business is large-area LED screens.

In 2020, Leyard announced its entry into the microLED industry, with a partnership with Epister to setup a Mini-LED and Micro-LED production site in Wuxi, China, in a $142 million investment. In 2021 CHN Energy Investment has installed the world's largest microLED display (216-sqm) using Leyard's displays.

Kura Technologies

Kura Technologies logoUS-based Kura Technologies, established in 2016, develops augmented reality (AR) glasses, and related technologies. The company has wide backing from a range of investors and Universities.

Kura's AR glasses are powered by a microLED microdisplay that company the develops in-house. Kura is also developing its own display controller chipset. The company's Gallium AR glasses offer 8K resolution, full-color, ultra-high brightness and a 150-degree FOV.


Silicon Core logoUS-based SiliconCore, established in 1997, develops driver chips for LED displays, and large scale indoor displays. SiliconCore says that its Common Cathode technology enables the highest performance, coolest operating and brightest direct-emission LED displays.

In recent years SiliconCore develops displays based on miniLEDs and microLEDs.


Raxium logoUS-based Raxium, established in 2017, develops microLED microdisplay technologies.

Raxium did not reveal much about its technology, beyond saying that it developed a monolithic approach to develop microLED microdisplays, with a pixel pitch of 3.5 um.


Raysolve logoHong Kong based Raysolve Technology, established in 2019, is a fabless microLED microdisplay producer. The company develops microdisplays based on its CoANODE architecture and innovative bonding technology.

Raysolve says that its innovative large size GaN-on-Silicon wafer-level integration technology enables the production of high quality microLED chips with high yields. In December 2021 the company raised $10 million (bringing its total funding to $15 million).


Sundiode logoUS-based Sundiode develops microLED microdisplays based on its stacked-RGB pixel structure.

In 2021, in collaboration with KOPTI and Jasper Display, Sundiode unveiled a microdisplay prototype that features 200 PPI and 100um pixels. The display is an array of stacked-RGB micro-LED pixels on a single chip bonded directly onto a Si CMOS backplane.


EpiPix was spun-off from The University of Sheffield in the UK, to commercialize technology for multi-color microLED arrays on a single wafer developed at the University’s GaN Centre for Materials and Devices.

The company is developing red, green and blue microLED epiwafers with a pixel size ranging from 30 microns down to less than 5 microns. EpiPix says that it achieved record-breaking IQE results.
