About us

QubeDot GmbH develops and manufactures microLEDs and microLED-displays based on the InGaN material system for particularly high optical performance and switching speeds. We offer our worldwide customers & partners ruggedized microLED displays and customized microLED solutions. Made in Germany, with a complete European supply chain.

QubeDot's core competency is its expertise in InGaN-based custom microLED solutions - starting with fully comprehensive consulting, design of lithography mask and processing in the fab. Our technology is used for various applications in industries such as metrology, defense, machine vision, integrated circuits, biology, optogenetics and microscopy.

QubeDot offers microLED solutions for applications that demand small emitter sizes, and often, small batch sizes too. From prototype to production, we partner with customers at every stage to engineer the right solution for their specific use case.

SMILE-platform

With our microLED arrays we offer the first ready-to-use SMILE-platform. SMILE is an acronym for
"Structured Micro Illumination Light Engine" and comprises our microLED-array product range with
different pixel numbers & sizes, wavelengths & intensities. All light sources are controlled directly from computer via USB, and pattern creation works immediately after installation. A SMILE-platform consists of a customized microLED chip, electronics, housing and a graphical user interface for control.
