The MicroLED-Info newsletter (January 10, 2023)

Samsung announced its 2023 microLED TV lineup, with a wide range of sizes - from 50-inch to 140-inch. The TVs will still be highly expensive, but Samsung is expected to reduce its prices, and in addition it will be possible (finally) to self-install the TVs.

The MicroLED CX range of TVs will include sizes of 50-, 63- 77-, 89-, 101-, 104- and 140-inch. Not all the TVs will ship at once and in all regions. It is expected that the main TV will the the 77-inch one. But at the expected high prices, these will be sold at very low volumes, most likely.

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.

AR developer Mojo Vision announced that as it finds it challenging to raise more funds, it is changing its focus to develop its microLED technology and "decelerating" its work on the smart contact lens system.

According to reports, Mojo Vision has laid off 75% of its employees - it is estimated that the company laid off around 100 employees (it had around 150 employees before the change). The company's CEO says that the its microLED display technology has "is significant near-term market potential".

TCL announced and demonstrated its latest AR smart-glasses, the RayNeo X2, which features a monochrome microLED display engine.

We do not have any information on the microLED display, but other specifications include a Snapdragon XR2 chipset and a wearable ring controller. The RayNeo 2 will ship to developers in Q1 2023, and TCL hopes to launch it as a commercial product later on.

MicroLED-Info and Perovskite-Info are happy to announce the 2023 edition of The Perovskite Handbook.
