Liquivision F1 heralds underwater OLED application
OLED displays have been incorporated for the first time into computers used by scuba divers.
However, the Liquivision F1, powered by Osram Opto Semiconductors' Pictiva OLED display, now offers divers a dependable illuminated display. The F1's OLED display is bright, viewable at sharp angles and its impressive performance has rendered all other diving computers (free and scuba) outdated.
Designed by record-holding freedivers, the Liquivision F1 is the first use of an OLED display in a dive computer. Traditional LCD diving computers are difficult to read underwater, mainly because they use standard low-contrast reflective LCDs. These are most often the same type seen in an ordinary wristwatch i.e. black characters on a gray background.
"Traditional diving computers are notorious for being unreadable in anything except the most ideal underwater conditions," said Eric Fattah, founder of Liquivision. "The Pictiva OLED changed this situation from the core. The OLED is extremely bright, and can be read at any angle. Most importantly, it consumes much less power than an LCD, so it can be on the entire dive."
Technical divers place their trust in their dive computer. Being unable to read it for any reason can interfere with the safety of the dive. For this reason, tech divers would bring numerous lights and back up lights, whose primary purpose was to illuminate their computer, rather than see marine life.
Pictiva OLED displays by Osram support both parallel and serial interfaces and are available in single color (yellow, orange, green, or white) with 4-bit grayscale capability. Operating half-life is 40,000 hours under ambient conditions.
