MICLEDI to develop red microLED AR displays in collaboration with IQE

Belgium-based microLED microdisplay developer 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.

Under this agreement, IQE will provide MICLEDI with a 200mm (8-inch) platform to scale and commercialise its technology to achieve high-volume production for red microLEDs. This geometry allows for compatibility with both standard 200 mm and 300mm silicon foundries, which enables the partnership to deliver economies of scale.

STRATACACHE CEO details the challenges and goals of the company's upcoming US-based microLED display production fab

Global digital signage solution provider STRATACACHE is constructing the first US-based complete display production facility in Eugene, Oregon. The future MicroLED E4 fab is planned to commence production in 2022, and the fab will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly.

XDC installs the world's first 300mm elastomer stamp based microLED transfer tool

MicroLED display technology developer X Display Company (XDC) announced that it installed the world's first 300 mm elastomer stamp based mass MicroLED transfer equipment late in 2020. This tool was installed in the US and the company hopes to start shipping several similar tools for its customers later in 2021.

STRATACACHE to build the first MicroLED production line in the US, mass production expected by 2023

Global digital signage solution provider STRATACACHE is embarking on a project to construct a microLED display production line in Eugene, Oregon. The company aims to start production in this fab at around 2022-2023, with plans to adopt these microLED displays in its own solutions.

The new factory (E4) will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly. The company plans to produce a wide range of displays, from tablet-sized panels to large-area displays. Some of these displays will be flexible and transparent as the company sees a market demand for such technologies. The yearly capacity of the E4 is expected to start at a 1 million square meters per year.
