A new guide to promising perovskite materials: The Perovskite Handbook

The MicroLED-Info team takes pleasure in recommending our new book - The Perovskite Handbook. This book gives a comprehensive introduction to perovskite materials, applications and industry. Perovskites offer a myriad of exciting properties and has great potential for the display industry.

The Perovskite Handbook

We believe that any display professional would find that perovskite materials are an area of focus that should not be ignored. The promising perovskite industry is currently at a tipping point and on the verge of mass adoption and commercialization and the first display-related perovskites are already reaching the market.

Plessey's Micro-LED display technology has been named a CES 2019 Innovation Awards Honoree

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced that it has been named a CES 2019 Innovation Awards Honoree in the Embedded Technologies category for its monolithic microLED displays.

Plessey developed a unique monolithic micro-LED process technology that can be used to produce Micro-LED displays without a pick-and-place stage. Plessey develops two generations of micro-LED displays. The first-gen Quanta-Brite are either LCoS or DMR display that are lit by an array of micro-LEDs, which Plessey says provide a more efficient and uniform display compared to current larger-LED lit displays.

Plessey purchased EVG's production wafer bonding system

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced a collaboration with EV Group (EVG), a wafer bonding and lithography equipment producer. As part of the agreement, Plessey purchased EVG's GEMINI production wafer bonding system to enable bonding and alignment at Plessey’s fabrication facility in Plymouth, UK.

Plessey says that the new system will enable it to bond its GaN-on-Si microLED arrays to the panel’s backplane at a wafer level. Plessey also says that EVG’s patented automated bond alignment system technology is suitable for Plessey’s requirements because it allows face-to-face alignment of the wafers with very high precision which will enable very small pixel sizes.

ALLOS and Veeco demonstrated the reproducibility of ALLO's GaN-on-Si epiwafer technology for uniform Micro-LED production

In November 2017 Veeco and ALLOS Semiconductors announced that the two companies have completed their micro-LED strategic initiative and demonstrated 200mm GaN-on-Si wafers for blue and green micro-LED production. ALLOS proprietary epitaxy technology was transferred onto Veeco's Propel Single-Wafer MOCVD System to enable micro-LED production on existing silicon production lines.

Yesterday ALLOS and Veeco announced the completion of another phase of their mutual effort to provide the industry with leading GaN-on-Silicon epiwafer technology for microLED production. The two companies now demonstrated the reproducibility of ALLOS’ 200 mm GaN-on-Si epiwafer technology on Veeco’s Propel MOCVD reactor when producing epiwafers for many prominent global consumer electronics companies.

Coherent reports new orders for its Micro-LED laser R&D tools

Laser equipment maker Coherent says that its customer have expressed a "reasonable amount of interest " in its Micro-LED solutions. The company is taking orders for R&D tools, but it says that mass production of Micro-LED displays is "still years away".

Coherent offers several laser-based tools used to produce Micro-LED displays, including Laser Lift-Off equipment (LLO) used to separate micro-LEDs from the sapphire wafer and Laser Induced Forward Transfer (LIFT) used to move micro-LEDs from the donor to substrate.
