Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The visual effect of interface presentation is poor when transitioning between the always on display (AOD) interface, screen locked interface, and desktop due to independent presentation of background wallpapers, failing to meet user requirements for cool and personalized display.

Innovation Solution

Implement a method where background wallpapers are dynamically and continuously played when transitioning between AOD, screen locked, and desktop interfaces, ensuring association and continuity of wallpapers and their upper-layer elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If background wallpapers are independently presented in different interface display stages (AOD, screen locked, desktop), then power consumption is reduced by using simple static displays, but the visual effect and continuity of interface presentation deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidvisual effect of interface presentation

Core Design Contradiction:

Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

The patent applies dynamics by transitioning from static independent wallpapers to dynamic continuous playback of background wallpapers across interface stages. The background wallpaper is transformed into a live wallpaper that plays continuously across AOD, screen locked, and desktop interfaces, creating visual coherence while allowing the system to adapt its playback behavior based on the active interface stage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements continuity of useful action by ensuring the background wallpaper plays continuously across all interface transitions without interruption. The live wallpaper maintains its playback state when transitioning between AOD, screen locked, and desktop interfaces, eliminating visual discontinuities and providing a seamless user experience.

Inventive Principle:

Principle #20Continuity of useful action

2Device complexity

If background wallpapers are independently presented in different interface stages, then device complexity is reduced by treating each interface separately, but the visual coherence and user experience deteriorates

Engineering Contradiction:

Improveimplementation complexity of interface managementVSAvoidvisual coherence of interface presentation

Core Design Contradiction:

Device complexityVSEase of manufacture

Solution Approach 1:

The patent merges the previously independent background wallpaper presentations into a unified continuous playback system. The live wallpaper service is consolidated to manage playback across all interface stages (AOD, screen locked, desktop) as a single continuous entity, ensuring visual coherence while reducing the need for separate wallpaper management logic for each interface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent applies universality by creating a live wallpaper system that serves multiple interface stages simultaneously. The same live wallpaper instance provides visual background for AOD, screen locked, and desktop interfaces, adapting its behavior to each context while maintaining continuity, thereby eliminating the need for separate wallpaper implementations for each interface type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If static wallpapers are used in AOD interface, then power consumption is minimized, but the visual appeal and personalization capability deteriorates

Engineering Contradiction:

Improvepower consumption in AOD modeVSAvoidvisual appeal and personalization

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies periodic action by implementing a live wallpaper that plays in a continuous loop across all interface stages including AOD. The wallpaper content is updated periodically through playback while maintaining energy efficiency by leveraging the low-power display capabilities of AOD mode, thus providing visual appeal without proportionally increasing power consumption.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent utilizes parameter changes by transitioning from static wallpaper images to dynamic live wallpaper playback. The system changes the temporal parameter of the wallpaper from static to animated, and adjusts playback parameters (such as frame rate and resolution) based on the active interface stage, thereby enhancing visual appeal while managing power consumption appropriately for each mode.

Inventive Principle:

Principle #35Parameter changes

AI summary

An interface display method and an electronic device are provided, which relate to the technical field of terminals. The method includes: In an AOD stage, an electronic device receives a screen-on operation. The electronic device displays a first interface when receiving the screen-on operation. The first interface includes a first wallpaper and a first wallpaper upper-layer element. In response to the screen-on operation, the electronic device exits the AOD stage and displays a second interface. The second interface includes a second wallpaper upper-layer element and a second wallpaper. The first interface is associated with or the same as the second interface.
