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.
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 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.
In 2018 HC SemiTek announced it is launching a new project to develop Micro-LED chips.
In 2018 Lextar introduced its first micro-LED chips - both RGB ones and color conversion ones, both suitable for mass transfer processes.
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.
Nichia develops micro-LED chips, transfer technologies and related equipment.
