Micro-LED Production - Page 7

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.

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.

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 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).

Toray Industries announced several new materials suitable for microLED production. The materials were developed in collaboration with Toray Engineering, developer of production and inspection equipment for the microLED industry.

The new materials announced today are a laser-transfer release material, a bonding material and a substrate side-wire material (used in a tiled display architecture). The bonding material and the side-wire material are both based on Toray's RAYBRID proprietary photosensitive conductive material.

VueReal announced that it has received volume orders for its transparent displays from automotive and aerospace customers. The company is producing custom displays at its pilot production line in Canada.

Back in June VueReal demonstrated its first transparent microLED display. The display is between 3 and 4 inches in size, with high brightness (over 3,000 nits) and very high transparency (85%). Vuereal says that its microLED cartridge- and printing- based production process enables the production of custom displays with high yield and high throughput.

According to a new report from Korea, Samsung plans to build a new TV production line in Vietnam, that will be dedicate to microLED TV production. The new plant will begin production in 2022, and will be used to produce its upcoming smaller 77-inch and 88-inch TVs. Samsung is also expanding its facility in Vietnam which is currently used to produce the 110-inch microLED TVs.

Samsung aims to reduce the production costs of its MicroLED TVs, and has launched a project that will develop a TFT backplane for its future TVs (to replace the currently used PCBs). The company hopes that this will enable it to reduce the production costs of its microLED TVs to the level of its 8K QLEDs. This sounds a bit optimistic, at least for TVs in sizes such as 77-inch or 88-inch.

USA-based eLux was established in 2016 as a spin-off from Sharp Labs of America, to commercialize a unique MicroLED production technology. A year ago we discussed the company's technology and business with its CEO, Jong-Jan Lee.

Today eLux announced that it has installed an automated fluidic assembly tool at its prototype fab in Taiwan. The new tool features fully automatic cassette-to-cassette fluidic assembly of ten display panels, each up to 15-inch in size. The tool has provisions for capture and recycle of microLEDs and assembly fluids to minimize operating costs, and its capacity can be expanded by adding two additional modules.

In 2020 Taiwan's LED developers Epistar and Lextar announced plans to establish a joint holding company, effectively merging the two companies, into Ennostar Incorporation.

During a recent investor conferences, Ennostar's CEO said that Epistar will gradually upgrade its miniLED production line in Taiwan to produce microLED chips. The plan is to reach a yearly capacity of over 400,000 6" microLED wafers. In the long term the company will focus its microLED production in Taiwan, while its Chinese factories will produce miniLEDs.

In 2019 San'an Optoelectronics announced that it aiming to build a $1.78 billion Mini-LED and Micro-LED production site in Hubei, with plans to start production in March 2021. Later it was reported that the construction is delayed due to the Covid-19 pandemic.

According to the latest news from China, the production is actually progressing well and San'an plans to start trial production by the end of the month. The second stage phase of the construction project is actually starting ahead of schedule - by half a year.

In 2020 Compound Photonics (CP) announced its high-performance IntelliPix microLED microdisplay backplane technology. CP's backplane supports resolutions up to 2048x2048 and a pixel pitch from 1.5 um and up.

Compound Photonics now announced a partnership with specialty foundry GLOBALFOUNDRIES (GF) to produce the IntelliPix backplanes. CP's devices will be realized on GF’s best-in-class 22FDX specialty semiconductor platform.
