They function differently, but the end result is light being shined through the display into your eyes. Sometimes the light can be very harsh, so these devices have included brightness controls essentially since the beginning.<\/p>\n<p>Ideally, you want the display to be dim when you\u2019re in a dark environment and bright in direct light. So every time the lighting in your surroundings changes, you may want to adjust the brightness to match. This becomes pretty tedious if you\u2019re doing it multiple times throughout the day.<\/p>\n<p>What if you didn\u2019t have to manually adjust the brightness yourself? What if your device could sense the lighting conditions and adjust the display brightness for you? That\u2019s where the idea for auto-brightness came from.<\/p>\n<p><strong>RELATED:<\/strong> <strong><em>How to Turn Off Auto Brightness on Android<\/em><\/strong><\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"How_It_Works\"><\/span>How It Works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-773340\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/12\/iPhone-notch.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"iPhone notch\" width=\"650\" height=\"350\" src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.shutterstock.com\/image-photo\/antalya-turkey-june-23-2020-new-1762295039\">Yalcin Sonat\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>Okay, so that\u2019s a great idea, but how does it actually work? How does a phone or laptop know how bright it is around you? Let\u2019s talk about sensors.<\/p>\n<p>Your phone and laptop have dozens of sensors inside. Phones, for example, have motion sensors, a proximity sensor, accelerometer, gyroscope, barometer, and an ambient light sensor. That last one is the magic behind auto-brightness.<\/p>\n<p>An ambient light sensor is actually pretty simple. It\u2019s a type of <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Photodetector\">photodetector<\/a> that has some fancy sensors to measure the amount of ambient light present. You can think of it as a type of camera.<\/p>\n<p>Imagine you take a photo and then combine all the colors from the photo to create the \u201caverage\u201d color. A light sensor calculates the ambient light in a similar way. That measurement unit is called \u201c<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Lux\">lux<\/a>.\u201d<\/p>\n<p>That\u2019s a lot of words to simply say the sensor can tell when you\u2019re outside under direct sunlight and when you\u2019re laying in bed with the lights off. It then adjusts the display brightness accordingly. The ambient light sensor can be found somewhere in the bezel on the front of the device.<\/p>\n<p><strong>RELATED:<\/strong> <strong><em>How to Turn Off Auto Brightness on iPhone<\/em><\/strong><\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"A_Bright_Idea\"><\/span>A Bright Idea<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As devices have continued to get more advanced, so has auto-brightness. Google Pixel devices have \u201cAdaptive Brightness,\u201d which adds AI to the mix. It learns how you adjust the brightness on your own and does it for you along with the light sensor.<\/p>\n<p>Some iPhones, iPads, and Macs have Apple\u2019s \u201cTrue Tone,\u201d which uses even more sensors to not only adjust the brightness, but also color temperature to match your surroundings. That\u2019s pretty neat.<\/p>\n<p>It\u2019s a simple concept executed with fancy little sensors.
