The most advanced multispectral 6-channel ambient light sensor, supplied and produced by ams for its biggest customer, Apple

For the semiconductor industry, the smartphone is a gold mine. Each component inside every OEM’s flagship phone holds substantial value for the component supplier, which sometimes gains a significant portion of the phone’s sales revenue too. Apple is one of the major OEMs that every supplier fights to work with, and for many years ams AG has been the world’s leading ambient light sensor (ALS) producer, due to its presence in every Apple iPhone.

ams produces most advanced multispectral 6-channel ambient light sensor in the iPhone X for its biggest customer : Apple - System Plus Consulting.

 

For the iPhone’s 10th anniversary, ams provided a custom version of its multispectral sensor, replacing and improving the iPhone’s ALS function.

Located in the phone’s front, above the main speaker, the ALS shares the flex PCB with the proximity sensor and the front microphone. The custom version provided by ams is a multi-spectral ALS in very long, narrow packaging (6 x 0.9mm).

The ALS’ architecture allows for large spectral sensing. Combined with a diffuser, the die sensor features six different cells, most likely dedicated to UV, red, green, blue, NIR1, and NIR2, thus providing a broad light spectrum. This allows the sensor to adapt the display color and brightness towards warm or cool-white based on the correlated color temperature (CCT) level of the phone’s environment.

This report analyzes the complete multi-spectral ALS, from the sensor die to the custom packaging developed for the device. This report also includes a complete cost analysis and a price estimate for the device.
