Ambient light

Functional testing

Extended battery life and easy-to-view displays by optimizing a device to its environment. Key aspects for a great user experience in the ever-connected world of today.


Ambient light sensors in a smart device make the device aware of its surroundings, resulting in reduced power consumption and viewing comfort. Ambient light sensors detect the amount of light available and help a processor to adjust the backlight or illumination of a display. Ambient light sensor (ALS) testing verifies the sensor's assembly and functionality.


In a managed environment, like in a dark room, an adjustable light source is located over the ambient light sensor and different luminance situations are simulated.
