Color sensor drives smartphone intelligent display management

May 12, 2014 // By Paul Buckley
Claiming an industry first, ams AG has introduced an integrated ambient light, color (RGB) and proximity sensor that is optimized for operation behind dark glass to drive intelligent display adaption in mobile devices.

The TMD3782 optical module is ideally suited for smartphones and tablets. The sensor integrated in the TMD3782 provides ambient light intensity (lux) and color measurement enabling mobile devices to automatically adjust their display’s color and brightness for the best viewing experience and power savings.

High-resolution displays are now standard features in mobile devices, making it critical they provide accurate colors and brightness while operating in a wide range of light sources, including fluorescent, incandescent and sunlight. The TMD3782 on-chip filters minimize the effects of ultra-violet and IR light and enable its photopic response thus improving the overall accuracy of light and color sensing.

Enhancing the user’s viewing experience across a wide range of lighting conditions offers mobile device manufacturers new means to draw consumers to their brand. The TMD3782 is able to sense light in a similar manner to the human eye, enabling more sophisticated control of the display brightness and color. The combination of ambient light and color sensing enables mobile devices to deliver more brilliant display colors and a superior viewing experience in all lighting environments.
