Module meets performance and space needs of ultra-thin mobile devices

Mouser now stocks the TMD3700 proximity and color sensor module from ams. The optical sensor module senses RGB color, ambient light, and proximity to provide OEMs with design flexibility and the ability to provide a better display viewing experience — all in the industry’s smallest footprint for color and proximity modules. The sensor module’s performance and small space requirements are optimal for next-generation mobile devices with ultra-thin profiles and narrow bezels. The module features a small 4mm × 1.75mm footprint with a height of just 1mm, making it ideal for next-generation mobile phones with extremely tight layout and mechanical design constraints. The module’s wide 45-degree field-of-view, ambient light sensing accuracy of ±10%, and operating range of 200mlx to 60klx behind dark glass all enable smartphones to measure the surrounding light environment and automatically adjust display color and brightness for optimal viewing. The sensor channels each have UV- and IR-blocking filters and a dedicated converter that allows 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 to achieve the best visual color accuracy. The device’s numerous features enable dynamic elimination of both electrical and optical crosstalk, which produces reliable proximity detection — a function that allows smartphones to disable the touchscreen display when held close to the user’s face. In addition, the module’s integrated IR LED is calibrated for maximum performance and consistent operation. The modules are supported by an evaluation kit. The kit includes a main controller board with a PIC microcontroller, USB 2.0 cable, a module daughter card, plug-and-play USB HID class drivers, and GUI software that allows users to control the proximity and color sensor settings.
