Indiglo
Indiglo is a brand name of Indiglo Corporation, solely owned by Timex for licensing purposes. Timex electroluminescent lamps, branded Indiglo, were introduced through Kmart in 1992 in the Ironman watch line. The technology is comparable to the Illuminator technology used by Casio.
Other watch models exhibit an Indiglo backlight that only lights up the numbers, rather than the entire LCD display, which is achieved by means of a specialized film that inverts the LCD transmissivity. The Timex Datalink USB uses this technology. Indiglo devices emit a distinct blue or white or other color. The name derives from the word indigo.
Indiglo has been used for other devices such as clock radios, electronic personal organizers, and nightlights. Timex has also used the Indiglo trademark for luminescent paint on the hands of their analog watches, while making no distinction between this product form and the electrically powered electroluminescent feature on their other watches.
