Small sensor module offers colour, ambient light and proximity sensing

An optical sensor module launched by ams is claimed to be the smallest on the market to deliver a combination of colour, ambient light and proximity sensing. It is said to provide OEMs with design flexibility and a better display viewing experience.

The TMD3700 measures 4 x 1.75mm with a height of 1mm, suiting next generation mobile phones with tight layout and mechanical design constraints. It has a 45° field of view, ambient light sensing accuracy of ±10%, and an operating range of 200mlux to 60,000lux behind dark glass. This enables smartphones to measure the surrounding light environment and automatically adjust display colour and brightness.

The TMD3700 colour sensor channels each have UV and IR blocking filters and a converter allowing simultaneous data capture necessary for accurate measurements. The combination of photopic colour and ambient light sensing enables smartphones to perform real-time adjustment of the display properties; such as white point, colour gamut and colour saturation.

The device eliminates electrical and optical crosstalk which allows for reliable proximity detection.
