What is Always On Display (AOD)?

Always On Display (AOD) is a feature that allows the screen of a smartwatch to remain partially active, displaying crucial information like time, date, and notifications without fully activating the display. Unlike traditional displays that go dark when not in use, AOD screens use low power to keep essential data visible, often with a simplified and dimmed interface to conserve battery life.

The Evolution of AOD Smartwatches

The concept of AOD isn't entirely new, having roots in the earlier days of digital watches. However, it has significantly evolved with advancements in display technologies, particularly with the advent of OLED (Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode) screens. These technologies enable individual pixels to light up independently, allowing parts of the display to remain active without consuming excessive power.

Early Beginnings

The first wave of smartwatches primarily focused on basic functionalities like fitness tracking and notifications. The displays would typically turn off to save battery, requiring a button press or wrist gesture to activate the screen.

The Advent of OLED and AMOLED

With OLED and AMOLED screens becoming mainstream, manufacturers like Samsung and Apple introduced AOD features that allowed for more efficient power usage. These screens could light up specific pixels to display minimal information, ensuring that users could glance at their watch without needing to activate the full display.

Modern Innovations

Today, AOD technology has become a staple in premium smartwatches. Innovations have further refined this feature, with adaptive brightness, color customization, and dynamic information updates. The Apple Watch Series 5 and later, along with Samsung’s Galaxy Watch series and BP Doctor smartwatches, exemplify the sophisticated use of AOD, combining it with robust battery management to provide a seamless user experience.

Advantages of AOD Smartwatches

The AOD feature offers numerous benefits that enhance the user experience:


The most obvious advantage is convenience. Users can quickly glance at their smartwatch to check the time, date, or notifications without needing to interact with the device actively. This hands-free approach is particularly useful in situations where using both hands isn’t feasible.

Aesthetic Appeal

AOD can add a touch of elegance and personalization to smartwatches. Many AOD-capable watches offer customizable watch faces, allowing users to select designs that reflect their style while still showing essential information.

Battery Efficiency

Despite initial concerns, modern AOD implementations are highly efficient. By using low-power display modes and intelligent battery management, smartwatches can maintain impressive battery life even with AOD enabled.

Enhanced Functionality

AOD isn’t limited to just showing time. It can display various data points like weather updates, calendar events, and fitness metrics, providing continuous, at-a-glance information.

Functions of AOD Smartwatches

AOD smartwatches offer a wide range of functions that make them versatile and indispensable gadgets:

Time and Date

The core function remains displaying the time and date, but AOD smartwatches do so with a flair, offering customizable watch faces that can be tailored to show additional information like weather, moon phases, or even stock updates.


AOD smartwatches can display notifications for calls, messages, emails, and app alerts. This ensures users stay informed without needing to pull out their smartphones constantly.

Fitness Tracking

Modern AOD smartwatches are equipped with sensors that monitor heart rate, steps, sleep patterns, and even advanced metrics like VO2 max and ECG readings. Having this information readily visible encourages users to stay active and mindful of their health.


For those who rely on their smartwatch for navigation, AOD provides continuous map visibility, ensuring users can keep track of directions without repeatedly waking the screen.

Music Control

AOD functionality extends to media controls, allowing users to play, pause, skip tracks, and adjust volume without activating the full display. This is particularly handy during workouts or commutes.


The Always On Display feature has revolutionized the smartwatch experience, blending convenience, functionality, and style into one seamless package. As technology continues to advance, we can expect even more innovative uses of AOD, further integrating these devices into our daily lives. Whether you're a fitness enthusiast, a busy professional, or simply someone who loves tech, an AOD smartwatch offers something for everyone, making it a worthwhile addition to your gadget collection.
