Belgium-based microLED microdisplay developer MICLEDI demonstrated a "Ferrari" red microLEDs on aluminium indium gallium phosphide (AlInGaP) starting material. The company says that these red microLED devices are produced using a CMOS-compatible flow, free of arsenide.
MICLEDI says that it uses advanced photolithography available in 300mm wafer fabs. The company's first red microLED on GaN is solidly in the red range with wavelength centered at 620nm and good full-width half-maximum (FWHM) of <50nm. This newest announcement of red on AlInGaP achieves 653nm wavelength at extremely narrow FWHM of <9nm.
In November 2022, MICLEDI demonstrated 630nm wavelength red GaN with a full-width-half-max (FWHM) in the range of 50nm. Earlier in 2022, MICLEDI announced a partnership with IQE, a supplier of compound semiconductor wafer products and advanced material solutions to the global semiconductor industry, to develop microLEDs for AR products.
In March 2022, MICLEDI announced that it will partner with GlobalFoundries in a manufacturing collaboration to develop microdisplays. MICLEDI's solution will be combined with GlobalFoundries' 22FDX platform to enable MICLEDI to mass produce microLED arrays.
In December 2021 MICLEDI demonstrated what it says is the industry's first microLED arrays-for-AR built on a 300mm CMOS manufacturing platform. In August 2022 the company announced a partnership with MicroLED Industry Association member QustomDot to develop full-color microLED microdisplays with QD color conversion. The company also launched microLED microdisplays with integrated micro-lenses, which it says it is a first for the display industry.
