Lumiblade tiles use OLED technology, which allows for a very homogenous surface light. Unlike LEDs, this light will never have those pesky hot spots. OLEDs work by passing low levels of electricity through thin layers of organic semiconductor materials. In other words, the tiles are a stack-up of films that can be electrically charged, causing them to become “excited” and emit light. Right now, the tile sizes are limited in size, but they can be linked together into endless configurations.
