These rainbow colored OLED lights are part of an interactive display created by artist Emory Krall for Universal Display Corporation. Utilizing colored OLED panels, the TLO (Triangle Light Objects or Transparent Light Origami) is designed to combine light in an additive way.

“The TLO is an intuitive demonstration of how a white OLED lighting panel is created: overlapping layers of red, green and blue OLED materials are sandwiched within a single panel, which therefore emits white light,” explains the designer.
