Micro LED technology builder VerLASE introduced a novel mass transfer technique for Micro LED display production based on its “Large Area Assembly Platform” (LAAP), which the company revealed in June, 2019. With similar concept, the company transfer the technology into a simpler, semiconductor-fab compatible solution based on Photo-Mechanical Actuation (PMA). According to VerLASE, the solution uses a novel formulation comprising of fab compatible chemistries and transfer stamp architecture in a unique way to deterministically pick-up a large ...

Apple just won another Micro LED related patent with other 63 patents issued on October 8, 2019, reported Patently Apple. The patent, titled “Optical Verification System of verifying Micro Device Transfer,” focuses on mass transfer process, which has been one of the most challenging issues that slow down Micro LED commercialization. (Image: the U.S. Patent and Trademark Office) In the patent, Apple described an optical verification method and mass transfer system which includes optical imaging and inspection for monitoring Micro LED transfe...

The development of Micro LED display technology has further materialized in 2019 in the form of more solid applications presented in big trade shows. Micro LED products demonstrations marked the intensified collaboration between industry players in the supply chain across the world. Researchers, chip makers, panel producers, equipment providers and application device developers have intensified their cooperation to accelerate Micro LED technology progress.

During the trade show, LEDinside visited exhibitions of equipment providers and attended conferences of fabrication process developers to find answers on all areas of Micro LED manufacturing. Below are displays and presentations made by companies that are expected to make crucial contributions to the Micro LED supply chain.

Successfully obtaining technologies able to mass produce Micro LED products, Korean mid-sized LED maker Lumens begins to produce both small- and large-sized Micro LED display prototypes planned to be showcased at CES 2018.

The Korean Institute of Machinery and Materials (KIMM) announced on 24th July that it developed a new technology to possibly facilitate the mass transfer process of Micro LED manufacturing, as Business Korea carried in its report.

A major bottleneck in the commercialization of Micro LED displays is the mass transfer of micron-size LEDs to a display backplane. Research by LEDinside, a division of TrendForce, reveals that many companies across industries worldwide have entered the Micro LED market and are in a race to develop methods for the mass transfer process. However, their solutions have yet to meet the standard for commercialization in terms of production output (in unit per hour, UPH), transfer yield and size of LED chips (i.e. Micro LED is technically defined as LEDs that are smaller than 100 microns).
