Texas Advanced Optoelectronic Solutions®, Inc., announced the first members of its next generation digital ambient light sensor (ALS) and proximity detection family that is designed to provide consumer electronics manufacturers with greater freedom to produce sleeker, more appealing and innovative product designs. These latest TAOS devices eliminate the need to use clear glass/plastic in front of the sensor or drill holes/slots into the display, bezel or frame in order for light to reach the sensor.
Specifically designed to operate behind darkened glass or other translucent materials, the TSL2771 device family provides both ambient light sensing and proximity detection in a single device that consumes far less power than currently available comparable solutions. Proximity detection is ideally suited for touch screen smart phones to automatically turn off the display or control other user functions and can also be used in laptops, desktop computers and monitors to conserve energy or maintain information privacy when the user is not present. Other emerging applications for proximity sensing technology include touchless display controls activation and management as well as human gesture detection.
