Description:

An innovative microLED technology based on a novel bottom-up growth technique is demonstrated. The novel technology allows for overcoming main fundamental limitations hindering further development of microLEDs. The technology allows for RGB emission within a single materials system (InGaN/GaN). Blue and green emissions have earlier been demonstrated, but now also a red emission peaking at 635nm is realized. The technology is suited for hybridization with extremely high accuracy, using a cold-bonding flip-chip method. MicroLED technology based on the pyramidal architecture is promising for manufacturing of micro displays for applications such as Head-Mounted-Displays (HMDs) and Head-Up-Displays (HUDs).
