Micro UV LED Chip (die)

Micro UV LED Chip size : 12ʂ x 24ʂ We can sell custom made micro UV LED chips with wavelengths from 385nm to 405nm.
Micro LED displays are being researched and developed as a next-generation display applied for AR glasses, VR glasses, and flexible displays. Because it is difficult to make efficient micro Red LED chips, we propose to apply micro UV LED chips instead.
We can obtain full color by exciting RGB phosphor by micro UV LED chips, and this method makes the mass transfer process and LED drivers simple, so its manufacturing cost is reasonable and looks realistic.
For detailes, please refer to the page of "Display" among "Applications".
