Mobile devices and laptops come with multiple sensors under their surface that help improve the user experience. Smartphone users are familiar with this Automatic brightness feature Which is mainly used in mobile devices. This is a feature that is available on both iOS and Android platforms. However, this feature is also being added to the latest laptops, MacBooks and Chromebooks. Here, we will discuss how Automatic brightness Features work.
What are the features of automatic brightness??
The auto-brightness feature automatically adjusts the brightness of the display according to its surroundings. Most smartphones and laptops come with LCD or OLED displays. Both of these types of screens can work differently, but their real function is to reflect light into your eyes through the display.
A bright display is ideal when you’re out in the sun, but it’s best to have a dim screen in low light conditions. The maximum brightness of most displays can be harsh on your eyes in a dark environment, so the manufacturers have included the necessary brightness controls. Thus, the auto-brightness feature saves you from the tedious task of manually adjusting the brightness more than once a day.
How do features work?
As mentioned earlier, our phones and laptops come with several sensors under their surface. Some of the sensors present in smartphones include proximity sensor, accelerometer, gyroscope, barometer, motion sensor, ambient light sensor and others. What is behind the auto-brightness feature is the ambient light sensor.
An ambient light sensor is a type of photodetector (it works almost like a camera) that can measure the amount of light ambient light around the device. The light sensor calculates the ambient light just like an image.
This sensor adjusts the brightness of the display according to the amount of light present around you. It understands when you are out in direct sunlight and when you are in bed with the lights off. Ambient light sensors are usually found somewhere in the front bezel of the device.
How have the features evolved over the years?
Some Pixel phones and some Samsung devices have “adaptive brightness” features that make AI foldable. It presumably learns how to manually adjust the brightness of your display and does the same for you. Samsung says, “It helps your phone to learn the screen brightness of your choice in different light.”
Apple’s “True Tone” feature not only uses more sensors to adjust the brightness but also tries to adjust the color temperature to match the user’s surroundings.
