According to reports, Google acquired Raxium, a US-based microLED microdisplay developer. The financial terms of this acquisition were not disclosed.

There's not much known about Raxium, beyond that it has developed a monolithic approach to develop microLED microdisplays, with a pixel pitch of 3.5 um.

Researchers from Japan's Toyohashi University of Technology and the Okinawa Institute of Science and Technology Graduate University have developed a flexible, multipoint microLED array film that can be flexibly attached to cover the brain and can illuminate specific brain regions.

The manipulation of neural activity by light (enabled by optogenetics), requires a thin, flexible and lightweight lighting source that is not toxic to living tissue. The new microLED film is highly suitable for this task, and the researchers hope that such devices will create a new area of neuroscience research aimed at comprehensively understanding the brain information that underpins how neural activity, behaviors, and disorders are linked.
