ams (SIX: AMS), a leading worldwide supplier of high-performance sensor solutions, released the TCS3430, the first XYZ tristimulus True Color sensor IC to be offered with a small footprint made for consumer devices such as notebooks, smartphones and tablets.
Offering digital measurements of illuminance (brightness) and chromaticity matching the CIE 1931 “Standard Observer” XYZ scale enabling True Color functionalities – which is the industry standard for quantifying the average human’s perception of light – the miniature TCS3430 could be used for functions such as display management, automatic white color balancing or color management.
OEMs which move from RGB color sensors to the new cost effective TCS3430 will be able to achieve dramatic improvements in camera and display performance, enabling users of mobile devices to enjoy:
The TCS3430 benefits from proprietary ams technology for fabricating interferometric optical filters directly on the wafer. The ams interferometric filters can be built with the spectral characteristics of the XYZ spectral responsivity model of the human eye. In the TCS3430, the filters provide five channels: X, Y and Z channels and two infrared channels. The IR channels are used for improved light source detection. The Y channel’s response to the green portion of the visible light spectrum provides a measure of illuminance, enabling the TCS3430 to operate as an ambient light sensor as well as a color sensor.
The TCS3430 is equipped as a packaged IC measuring 2.41mm x 1.75mm x 1.00mm. The opening of the sensor needs to be covered by an achromatic diffuser. The TCS3430’s high sensitivity and wide dynamic range mean that it can be mounted behind dark or transparent cover glass. It operates from a 1.8V supply and provides an I2C interface to a host processor.
“The TCS3430 is the smallest available True Color sensor. It enables consumer products to drastically improve and manage their color and brightness performance, much more precise to the ambient light conditions and to the True Color of images”, said Kevin Jensen, Senior Marketing Manager for Color Sensors at ams. “Consumers are becoming more and more aware of the concept of color. Recent surveys confirm that consumers find it challenging to match items from their home to store or online products. The precise white point balancing of images does not only improve the quality of images for designers and professionals but also assists general consumers to make decisions and reduce overall product returns”, he added.
