Digital Color Sensors

TAOS has announced the TCS3x71 and the TCS3x72 digital color RGB sensors with an infrared blocking filter and a proximity sensor. The sensors provide color measurement and, when coupled with an IR LED, offer proximity detection over a wide range of lighting conditions and through a variety of attenuating materials. The IR blocking filter is integrated directly on-chip and localized only to the color sensor photodiodes. High-accuracy color sensing requires eliminating errors caused by the IR spectral component in light sources. The on-chip IR blocking filter minimizes these effects, eliminates requirements for external IR filtering, and enables the devices to perform ambient light sensing (ALS). ALS instruments are used in display-based devices to enable automatic backlight brightness control based on lighting conditions for optimum viewing and energy conservation.
