UK-based IQE is a pure play compound semiconductor provider with a global footprint, that supplies advanced materials and wafer products to the semiconductor industry. IQE business segments include wireless, photonics and CMOS.
Over the years IQE collaborated with several microLED makers regarding microLED wafers. In May 2023 the company launched a new portfolio of 200mm (8”) Red, Green and Blue epitaxial wafer products for microLED display qualification.
Based in Xiamen City and established in 2017, XM-Plus (Xiamen Lingyang Huaxin Technology Co.) designs and produces display driver ICs. The company offers drivers for LCDs, Mini-LEDs, Micro-LEDs and AMOLED displays.
Ireland-based Rapt Touch (RAPT) is a provider of optical multi-touch systems for display makers and systems integrators. RAPT developed a unique and patented optical touch technology that is fully compatible with microLED displays, at all sizes.
RAPT's FTIR technology is based on low-cost LEDs that create an optical mesh of infrared light signals, read by photodetectors. The LEDs and the photodetectors are placed on the edge of the display. The performance is not affected by capacitive coupling or display pattern noise, and can be used on any screen size.
RAPT's solution offers superb optical and touch performance and is highly compatible with OLED and microLED displays. The technology is cost effective as it is based on off-the-shelf components and its costs grow linearly with size (unlike other touch solutions).
RAPT Touch is a privately held company, with over 90 issued patents. RAPT’s products have already been deployed in several projects and systems, including Google’s 55” Jamboard, and HiteVision products.
Established in 2012 in Korea, Soft-EPi that specializes in GaN-based epitaxial growth using MOCVD equipment.
The company supplies GaN Template on sapphire, non-polar GaN templates, GaN-free AlGaN Template on PSS, and UV-A epi wafers. For the microLED market, Soft-EPi developed a red gallium nitride LED epiwafer technology.
Shin-Etsu Chemical is Japan's largest chemical maker, and one of the leading chemical makers in the world. The company's leading the market for polyvinyl chloride, semiconductor silicon and photomask substrates.
Shin-Etsu has developed several materials used in the production of MicroLED displays, including a microLED stamp and temporary support substrates used for cleaning and transfer processes.
Shin-Etsu Engineering has also developed a range of equipment systems for the production of microLED displays - including LLO systems, bonding/debonding equipment and high-speed repair systems.
Taiwan-based Ultra Display Technology developed a microLED mass transfer solution based on customized flat mass-transfer stamps.
The company's product is the stamp with the LEDs already in place, for microLED display makers to directly deploy on their display substrates
Austria-based FAMETEC, a member of the EBNER Group of companies, produces wafers grown using a McSap (multi net shape c-axis Sapphire boules) process. The company produces high-end 6", 8" and 12" epi-ready sapphire wafers.
FAMETEC produces wafers specifically for microLED growth,and is shipping wafers to a tier-1 Asian microLED developer.
TLi (Technology Leaders & Innovators) is a Korea-based developer of display drivers, for LCDs, OLEDs and microLED displays. The company's products includes timing controller, driver ICs and ROIC.
TLi developed a microLED driver IC with Common Anode and Common Cathode, and aims to start sampling its first product by the end of 2021.
US-based Amorphyx develops amorphous-metals based display backplanes, which can be used to drive displays using quantum-tunneling. The company says that such backplanes will enable extremely fast conductivity and thus "unlimited" refresh rates.
Amorphyx's AMNR-based backplane are compatible with LCDs, OLEDs, microLED and e-paper displays.
The Fraunhofer Institute for Applied Polymer Research (IAP) develops bio-based and synthetic polymers, from the laboratory to the industrial scale. Applications are diverse across many markets, such as bio-based packaging, lightweight materials, truck tires and more.
The Fraunhofer IAP is active in the display industry, with its IAP functional polymer systems division looking into a broad range of materials, including light-emitting polymers and quantum dots. The focus lies in solution processing of these materials with a strong focus on printing methods.
Specifically for the MicroLED industry, the institute developed quantum dot materials as light converting materials for microLEDs. The IAP participates in the CoCoMe research project that develops printed QD color filters.
