Agilent Turns on Mobile Light with Ambient Light Photo Sensor

5/13/2003 - Agilent Technologies Inc. (NYSE: A) introduced the Agilent Ambient Light Photo Sensor (HSDL-9000), which detects the amount of light at any given time and sends a signal to adjust the backlighting as necessary in a mobile screen or keypad. If there is sufficient ambient light, the backlighting is not turned on, thereby extending battery life in mobile electronic devices such as mobile phones, PDAs and laptop computers.

Agilent's new device outperforms silicon photodiode light detection solutions because its spectral response peaks at the same frequency (550 nm) as the human eye. It accurately predicts when backlighting is needed to be able to see a display clearly, especially in different light sources such as fluorescent and halogen. The Agilent HSDL-9000 performs equally well with all light sources, and, as backlighting is only necessary about 40 percent of the time (1), the new Agilent HSDL-9000 can add significant time between battery recharges. This is especially important considering the growing use of color LCD displays, which consume much more power than monochrome LCDs.

"With battery life at a premium in today's multi-function devices, Agilent's new ambient light detector is an important component for our customers' new mobile designs," said Kee Hane Ngoh, operations manager of Agilent's Infrared Products Operation. "In addition to battery-powered handheld devices, we also see applications for this technology in automobiles and other products based on its superior spectral response."

"The Ambient Light Photo Sensor adds to Agilent's impressive line-up of products for mobile communications, including FBAR filters, E-pHEMT power modules, embedded cameras, infrared transceivers, and surface-mount LEDs," said Colin Chin, vice president of worldwide sales and marketing for Agilent's Semiconductor Products Group. "No other component vendor offers all of these solutions for mobile appliances."
