InfiniLED, backed by ScienceWorks Ventures plc and a Tyndall National Institute (UCC) spin-out, has signed an access agreement with Tyndall National Institute, Cork (Tyndall).

Under the agreement, InfiniLED’s engineers will work within the institute’s ISO 9001 Certified Compound Semiconductor cleanrooms to fabricate μLED (MicroLED) technology.

In MicroLEDs, a parabolic structure is etched on the back of the LED wafer to focus the light generated into a collimated beam - the core differentiator of the μLED technology. These structures are effectively micro optics integrated directly at the LED wafer level.

There are a number of benefits of the MicroLED over conventional LEDs. The MicroLED is a planar LED structure based on a sapphire wafer – one of the simplest, lowest and most common LED wafer technologies used in conventional LEDs. Also, a MicroLED pixel can vary from in size from approximately 10 to 25µm and the emitting surface is minimised to the region near the focal point of the parabolic structure resulting in the collimated light. What's more, the light is projected perpendicular to the sapphire and does not get trapped and even better, the MicroLED concept can be applied to all LED materials (blue, green, red, NIR, UV).
