Coherent publishes new white paper to discuss the role of lasers in microLED production

This is a sponsored post by Coherent

Coherent is a leading global supplier of lasers and photonics technology. For the MicroLED industry, Coherent provides several solutions from a single laser source, optical systems up to an integrated system for the three vital processes in MicroLED fabrication – Laser Lift-Off (LLO), Laser-Induced Forward Transfer (LIFT), and Repair/Trimming.

Coherent recently published a new white paper that provides an update on how high-energy ultraviolet laser beams enable LLO and LIFT processes. The white paper shows the importance of a perfect combination of laser and optical design to a how these lasers ensure placement accuracy and mass transfer that will remain future-proof as microLED chip die size continues to shrink.

Visionox reveals that its full-process pilot line is now capable of producing microLED displays

Visionox reveals that the company's MicroLED pilot line, which is the first full-process line built in China, is now capable of producing displays, from driver backplane, through transfer process to full module production. The LED chips themselves are produced by a third party.

Last year Visionox has established a subsidiary called Chenxian Optoelectronics to handle its MicroLED project. Visionox's strategy for the next five years is to focus on OLED and MicroLED displays (the company does not produce LCD displays, so this strategy is not a surprise).

Youngwoo DSP to lead a Korean effort to develop microLED display technologies

Korea-based test equipment maker Youngwoo DSP announced that it was chosen to lead a new Government-funded project to develop ultra-small microLED package technology (likely this refers to a LED transfer and assembly technologies).

The four-year project (which will end by December 31, 2024) will be awarded with a budget of 25.36 billion Won ($21.4 million USD). The project's goal is to enable the production of 360 PPI displays. The core technology will be around the alignment precision, it seems

We talk lasers in the microLED industry with Bolite Optoelectronics' CEO

The founder and General Manager of Bolite Optoelectronics, Dr. Bowen Cheng, was invited to present at the recent Touch Taiwan 2021 Conference in April. The title of his talk was “Laser Processing Applications for the Manufacturing of Mini and MicroLED Displays.” Since it was presented in Mandarin only, microled-info.com caught up with Dr. Cheng to learn more about this trending subject and the company he started.

Laser repair equipment for TFT arrays (Bolite in partnership with Contrel Technology)

Q: Dr. Cheng, can you please tell us a little about your background, prior to starting Bolite?

I was a research engineer at Xerox PARC and helped develop surface micromachined microspring interconnects in a project funded by the U.S. Army Research in collaboration with Oracle. I was also a vital member of the team that successfully demonstrated the world’s shortest wavelength diode laser at the time, a 250 nm UV laser for military applications. With these experiences in both semiconductor laser processing and MEMS processing, I decided to start Bolite and build a team to develop state-of-the-art laser solutions for microprocessing applications.

Q: I must admit I’ve not heard of Bolite before. What differentiates you from other laser microprocessing companies?

ETRI researchers develop a novel method to produce microLEDs using a new film material

Researchers from Korea's Electronics and Telecommunications Research Institute (ETRI) developed a new process to produce microLED displays, which they say can be highly cost effective.

MicroLED production using SITRAB (ETRI)

The new process is based on a novel film-like material developed at ETRI, called SITRAB. Using lasers, the process apparently detaches the microLED from the original epiwafer and bonds it to the SITRAB film in the same process step. The LEDs are then transferred to the final target backplane.

3D-Micromac launches a new microLED LIFT mass transfer tool

3D-Micromac announced a new microLED mass transfer tool, called microCETI. The company says its new technology can be used to transfer over 130 million microLEDs per hour.

MicroCETI is based on a laser-induced forward transfer (LIFT) process that can support almost any microLED material and shape. The tool also includes optional modules - a laser lift-off (LLO) module, and a single LED die repair module.
