Solution Overview

Problem

Current always-on-display (AOD) screens are monotonous and lack flexibility in display options.

Innovation Solution

An AOD method that dynamically changes the display based on external interactions, such as user gestures or device connections, allowing for flexible display of images or videos, including the use of motion videos and transition images to enhance user engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the always-on-display screen displays static images only, then power consumption is reduced, but display flexibility and user engagement deteriorate

Engineering Contradiction:
Improvedisplay flexibilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The display switches between static images and motion videos based on detected user interactions. Motion videos are played periodically when triggered by gestures or events, then return to static display state, creating a periodic action pattern that balances engagement and power consumption

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The display content transitions from static to dynamic (motion video) based on external triggers. The system dynamically adjusts display behavior by detecting user gestures, device orientation changes, or connected device events, making the display adaptable rather than fixed

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If motion videos are displayed continuously on the always-on-display screen, then user engagement is improved, but power consumption increases

Engineering Contradiction:
Improveuser engagementVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Motion videos are played in periodic intervals triggered by specific events (gestures, orientation changes, device connections) rather than continuously. After each video playback, the system returns to static display mode, creating an on-demand periodic action pattern that reduces overall energy consumption while maintaining user engagement

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If the display switches between different images frequently, then display flexibility is improved, but display stability and smoothness deteriorate

Engineering Contradiction:
Improvedisplay flexibilityVSAvoiddisplay smoothness
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system prepares transition images in advance to bridge between static images and motion videos. These pre-prepared transition elements ensure smooth visual transitions when switching display states, preventing abrupt changes that would disrupt display stability

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments of this application provide an always-on-display method and an electronic device. The method includes: displaying, by an electronic device, an always-on-display screen, where the always-on-display screen includes a first image of a first display object; in response to detecting by the electronic device that an external object satisfies a first preset condition, displaying, by the electronic device, a second image of a second display object, where the second image is different from the first image. In the embodiments of this application, the always-on-display screen displayed by the electronic device can change according to the external object. When the external object satisfies a preset condition, a corresponding image or motion video is displayed, so that the always-on-display screen can be flexibly displayed.
