Press Release Summary:
Featuring red, green, and blue filters, Models TCS3404 and TCS3414 derive color chromaticity and illuminance of ambient light with 16 bits of resolution for managing LED and CCFL display backlighting. Both include internal infrared-blocking filter, which eliminates error resulting from IR spectral component of light source. Housed in 2.095 x 1.875 mm chip-scale packages, devices automatically eliminate signal fluctuation resulting from ac lighting flicker without external capacitor.

TAOS, Inc. Announces Industry's Smallest RGB Digital Color Light Sensors with Infrared-Blocking Filter
New TAOS Digital Color Light Sensors Provide a Means for Deriving Color Temperature and Chromaticity Coordinates to Manage LCD Display Backlighting
September 22, 2008 (Plano, TX) - Texas Advanced Optoelectronic Solutions®, Inc. (TAOS; www.taosinc.com) today announced the industry's smallest RGB Digital Color Sensors. The TCS3404 and TCS3414 Digital Color Light Sensors with integrated red, green and blue (RGB) filters can derive the color chromaticity and illuminance (intensity) of ambient light with 16-bits of resolution for managing light-emitting diode (LED) and Cold Cathode Fluorescent Lamp (CCFL) display backlighting. Applications that will benefit from these capabilities include televisions, industrial and commercial signage, architectural lighting, and embedded display calibration.
The TCS3404 and TCS3414 devices can help white-color balance a display panel or captured image in diverse lighting conditions and manage RGB LED backlighting to maintain color consistency over an extended period of time. They can also be used to automatically adjust the display brightness of a backlight to extend the battery life, increase lamp life, and provide optimum viewing in diverse lighting conditions.
Both devices are packaged in a six-lead chipscale package, providing a very small footprint that measures 2.095 mm by 1.875 mm with a height of only 0.685 mm. Moreover, the chipscale package includes an internal infrared-blocking filter that eliminates the error resulting from the infrared spectral component of the light source while measuring light intensity and color as the human eye sees it without the need for an external filter. Additionally, the patent pending in-package trim capability minimizes device-to-device and system-to-system tolerance allowing very precise repeatability to be attained.
The TCS3404 and TCS3414 automatically eliminate signal fluctuation resulting from AC lighting flicker without an external capacitor. Programmable analog gain and integration time support a dynamic range of 1,000,000-to-1 in the TCS3404 and TCS3414. A synchronization input provides precise external control of the sensor's integration cycle allowing the internal conversion cycles to be synchronized to a pulsed or pulse-width-modulated light source. The synchronization mode can either be internally timed or externally timed. The manual timing control feature can be used to manually start and stop the integration time period. The device can support free-running and serial-bus-controlled integration modes.
"Today's announcement of the industry's smallest integrated RGB color sensors with a digital interface underscores the continuing TAOS commitment to provide world class leadership in three key technologies: light sensing, color sensing and packaging," Carlo Strippoli, Vice President of Marketing and Sales for TAOS, Inc. "At TAOS, one of our goals is to combine these three technologies in products that will further enable the optoelectronics market to realize its full potential."
The TCS3404 and TCS3414 have a wide operating temperature range of -40 degrees Celsius to 85 degrees Celsius and provide a 16-bit digital output with SMBus (TCS3404) at 100 KHz or I2C (TCS3414) at 400 KHz. Pricing for the TCS3404 and TCS3414 is $2.29 in quantities of 1,000 pieces.
