What is Always On Display (AOD)?

A feature called Always On Display (AOD) is showing up more frequently on modern smartphones. It's a function that enables information to be displayed on your phone's screen even when it's locked, without requiring you to turn it on. This feature has become popular because it can be useful in many situations and can save you time and battery life. We'll discuss what AOD is, how it functions, as well as its advantages and disadvantages, in this blog post.

What is Always On Display?

A smartphone's screen can display information like the time, date, battery life, and notifications even while it is locked thanks to a function called Always On Display. The function displays the information you select to show by keeping a tiny section of the phone's screen lighted continuously. This implies that you can view this information without unlocking your phone or pressing any buttons.

The function of Always On Display

It's crucial to be aware that the majority of contemporary smartphones employ OLED (organic light-emitting diode) panels in order to comprehend how AOD functions. Because each pixel in an OLED panel emits its own light, unlike typical LCD screens, a pixel that is off will not emit any light. Unlike LCD screens, which feature a backlight that illuminates the entire screen even when some areas of the screen are meant to be black, this type of display has no backlight.

AOD commands the phone's processor to keep a tiny section of the screen illuminated continuously. The information is displayed in this area of the screen, which is typically found close to the bottom. AOD doesn't eat as much battery as you might assume because the rest of the screen is still off.

The advantages of always-on displays

Time savings is one of the key advantages of AOD. You may quickly peek at your phone rather than unlocking it each time you want to check the clock or see if you have any notifications. If you're at a conference or other situation when it's not convenient to unlock your phone, this can be really helpful.

You may conserve battery life by using AOD.

Drawbacks of Always On Display

AOD can be distracting, which is one of its main downsides. AOD might not be the best choice for you if you are someone who is easily distracted by notifications or other information on your phone's screen. Also, if you value your privacy, you might not want information to remain visible on your phone's screen even while it is locked.

AOD also has the disadvantage of reducing battery life. AOD uses some power even though it doesn't use as much battery as you might assume. As a result, you might wish to switch off AOD if you're trying to extend the battery life of your phone.
