Researchers from the Beijing Institute of Technology and MIIT have developed perovskite quantum dots microarrays with strong potential for quantum dots color conversion (QDCC) applications including micro-LEDs displays.

Perovskite quantum dots (PQDs) hold potential as an attractive material and can resolve some of the problems found in conventional QDCC. While perovskite quantum dots are relatively new, they have already been shown to have attractive properties that make them extremely suited for electronic and optoelectronic applications.

Kulicke and Soffa Industries (K&S) announced that it has received two purchase orders, from two separate customers, for its LUMINEX, a disruptive laser-based mini and micro LED die-transfer solution.

K&S says that its highly flexible system is capable of single die transfer, multi-die transfer and mass transfer, supporting sorting, mixing, re-pitching and placement process steps. The broad flexibility of this system addresses the growing advanced display value chain and supports needs of LED, OSAT, panel and display suppliers.

The Korean Ministry of Trade, Industry and Energy is funding a new five-year project that aims to develop microLED display technologies in Korea, to support research at small and medium-sized enterprises and providing services for the industry such as consulting, patent development, and product commercialization strategy programs.

There are four participating organizations in the new project: Electronic Display Industrial Research Association of Korea, Korea Photonics Technology Institute, Korea Electronics Technology Institute, and Korea Automotive Technology Institute. The total project's budget is 18.3 billion Won ($14.8 million USD).

China-based Nationstar Optoelectronics announced a new "cooperation agreement" with Huawei for the development of mini-LED and micro-LED display technologies.

The two companies will, it seems, conduct "in-depth innovation" in these fields, and will open a joint innovation center. The company did not disclose any more details regarding the microLED project.
