China-based MicroLED microdisplay developer Jade Bird Display is building a 650 million Yuan ($92 million USD) display production line in Hefei, China. The construction of the building is already at a final stage.

It is estimated that JBD will be able to produce around 120 million panels in this fab. The company's current main product is a 0.13" VGA panel , so it is likely that JBD is referring to 120 million 0.13" panels.

AR glasses developer Kura Technologies, which is using an in-house develooped microLED display its products, announced a partnership with TSMC to build its initial custom micro-LED display chipset.

The company's custom mixed-signal display driver integrated circuits and other supporting devices, have already been successfully taped out on a standard, high-volume CMOS node at TSMC. Kura says that its DDIC is the smallest process node ever used on a micro-display driver and is also the world’s fastest micro-LED driver.

Researchers from Xerox PARC have developed a new micro-transfer printing technique that can be used to mass-transfer microLED devices. This technology offers high performance, simple and robust structure, and high process scalability and flexibility.

The new technology uses thermally induced adhesion modulation of shape memory polymer (SMP) materials. The idea is to use a print head that uses an individually-addressable micro-fabricated resistive heater array, which locally delivers heat for transfer of single microLED devices.
