Abstract:
Alarm clock LED displays are the grandparent of today's multipurpose LEDs. After the blue variety came along in the 1990s, engineers were able to combine them with red, green and yellow LEDs to create a beam of white light with potential beyond their use in a host of electronic gadgets. Even more recently, quantum dot nanotechnology is helping to create broader-spectrum LEDs with less of a blue hue.
