Aixtron is upbeat on the microLED industry, says orders for its production tools have started to kick in

During Aixtron's Q1 2022 financial results conference call the company's CEO made some interesting comments on its microLED business and the market in general.

Aixtron says that it sees the microLED display industry advancing "as expected". Demand for its microLED production tools has "started to kick in". The company is "increasingly confident" that we will 'soon' see commercial microLED displays on the market.

Visionox developed wearable and tiled microLED display samples

In December 2021, Visionox announced that it finished the construction of its MicroLED pilot line, which is the first full-process line built in China. The pilot line can produce complete displays, from driver backplane, through transfer process to full module production. The LED chips themselves are produced by a third party.

During Visionox's 2022 Technology Innovation Launch Event, the company announced that it has successfully built 1.84" wearable microLED display samples, in addition to glass-based 12.7" tiled display modules. Visionox did not reveal any more details about these new display samples.

HC Semitek to use Aixtron's G5+ C MOCVD systems for microLED production

Aixtron announced that Wuhan-based HC Semitek is using Aixtron's Planetary AIX 2800G4-TM (IC2) and AIX G5+ C MOCVD systems to produce microLEDs. All of these systems, shipped in Q4 2021, feature a configuration of 8x6 inches.

Aixtron says that this AIX G5+ C system uses wafer-level control (based on Auto-Feed Forward) of the film surface temperature during the epitaxial process in combination with Ultraviolet (UV) pyrometry. This warrants, according to Aixtron, a very accurate control of the Indium incorporation into the Multi-Quantum wells (MQW), which will ultimately define the wavelength consistency among all produced wafers

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.

San'an and CSoT launch their microLED Joint Venture

In March 2020, we reported that CSoT (owned by TCL) and San'an Optoelectronics have agreed to co-develop micro LED materials and production processes and equipment, in a 300 million Yuan (around $43 million USD) investment.

A few days ago it was reported by the Xiamen Xiang'an Industrial Zone that the new CSoT/San'an joint project have been officially launched. CSoT and San'an Optoelectronics established a new company called Xiamen Xinying Display Technology, which will establish an R&D base in the Xiang'an industrial zone.

The Perovskite Handbook - 2022 edition

MicroLED-Info and Perovskite-Info are happy to announce the 2022 edition of The Perovskite Handbook. This book is a comprehensive guide to perovskite materials, applications and industry, and it is now updated to January 2022 and lists recent developments and new companies, initiatives and research activities.

Perovskites are an exciting class of materials that feature a myriad of exciting properties. Perovskites are now entering the display market, with applications in quantum dots, LEDs, lasers and more.

The Perovskite Handbook

Reading this book, you'll learn all about:

  • Different perovskite materials, their properties and structure
  • How perovskites can be made, tuned and used
  • What kinds of applications perovskites are suitable for
  • Perovskites Quantum Dots
  • Perovskite solar cells, their merits and challenges
  • Perovskites-based LEDs
  • The state of the perovskite market, potential and future

The book also provides: a history of perovskite research, a guide to perovskite companies and developers, information on leading collaboration and development projects, a comprehensive list of perovskite companies and much more!

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).
