Belgium-based microLED microdisplay developer 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. MICLEDI says that the companion integrated circuits will provide the image processing, driver, and control functions necessary to complete the display modules using wafer-to-wafer hybrid bonding.

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.

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 the Korea Institute of Machinery and Materials (KIMM) have developed a stretchable microLED display, that can be stretched in both directions. The researchers say that the display can stretched by up to 25% without distortion to the image.

The researchers report that they have managed to successfully fabricate a 3" microLED display. This was achieved by using metamaterials with unique mechanical properties that do not exist in nature - mainly that if they are stretched in one direction, they also stretch in the perpendicular dimension, and so the display is not distorted. They term the display a 'metadisplay'.

MicroLEDs are seen as the future of the display industry, bringing higher brightness, more efficient and longer lasting displays that will enable new and exciting production paradigms and business models.

MicroLED-Info is now offering companies a comprehensive private microLED seminar that will cover the present and future of the microLED industry and market.
