August 3, 2016 -- ams AG, a provider of sensors and analog ICs, launched the TMD3700 optical sensor module that delivers a combination of color (RGB), ambient light and proximity sensing, providing OEMs with design flexibility.
The TMD3700 footprint, at 4.00 x 1.75mm and with height of 1.00mm, is ideal for next-generation mobile phones with extremely tight layout and mechanical design constraints. It’s wide 45-degree field-of-view, ambient light sensing accuracy of +/-10% and operating range of 200mlux to 60Klux behind dark glass, enable smartphones to measure the surrounding light environment and automatically adjust display color and brightness for optimal viewing.
The TMD3700 color sensor channels each have UV and IR blocking filters and a dedicated converter allowing simultaneous data capture necessary for accurate measurements. The combination of photopic color and ambient light sensing enables smartphones to perform real-time adjustment of the display properties; such as white point, color gamut and color saturation, to achieve the best visual color accuracy.
The TMD3700 features allow dynamic elimination of both electrical and optical crosstalk producing reliable proximity detection; a function used by smartphone manufacturers to disable the touchscreen display when it is held close to the user’s face. In addition, the module’s integrated IR LED is calibrated for maximum performance and consistent operation.
