Rapt Touch

RAPT Touch logoIreland-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.


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 logoShin-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.
