Solution Overview

Problem

Foldable electronic devices with differing screen dimensions or ratios between outer and inner screens result in inconsistent element display, impairing user experience.

Innovation Solution

An information display method for foldable electronic devices that includes detecting operations to unfold the screen beyond a preset angle, allowing the first screen to display a subset of cards in different positions, and adjusting the display based on priority and user interactions to maintain continuity of content visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the home screen elements are displayed consistently on both outer screen and inner screen, then the user experience is improved, but the display adaptability to different screen dimensions and ratios is reduced

Engineering Contradiction:
Improveuser experienceVSAvoiddisplay adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic display adaptation by detecting the current screen state (outer screen or inner screen) and automatically adjusting the display layout, card arrangement, and element positioning accordingly. The system transitions between different display modes based on real-time screen identification, ensuring optimal visualization on each screen type while maintaining consistent content accessibility and user interaction patterns.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different display strategies to different screen contexts. For the outer screen, it uses a first display mode optimized for its dimensions and ratio, while for the inner screen, it uses a second display mode tailored to its characteristics. This local optimization ensures that each screen displays content in the most appropriate format for its specific physical properties, resolving the contradiction between consistency and adaptability.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the screen is folded to switch between outer screen and inner screen, then the display versatility is improved, but the element display consistency deteriorates

Engineering Contradiction:
Improvedisplay versatilityVSAvoidelement display consistency
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent performs preliminary screen state detection and display mode preparation before the actual screen switching occurs. By anticipating the fold state change and pre-configuring the appropriate display mode, the system ensures seamless transitions while maintaining element consistency within each mode. This preliminary action prevents display inconsistencies during the transition process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a universal display system that can adapt to multiple screen configurations (outer screen and inner screen) through a single unified framework. The system uses a common detection mechanism and adaptive rendering engine that handles both screen types, ensuring that while the specific display parameters differ, the underlying content delivery and user experience framework remains consistent and reliable across both screen modes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If different display modes are used for outer screen and inner screen, then the display optimization for each screen is improved, but the content continuity between screens deteriorates

Engineering Contradiction:
Improvedisplay optimizationVSAvoidcontent continuity
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism that continuously monitors the current screen state and adjusts the display mode accordingly. The system detects whether the outer or inner screen is active and provides feedback to the rendering engine, which then applies the appropriate display optimizations while maintaining content continuity. This real-time feedback loop ensures that content is preserved and properly displayed regardless of which screen mode is active.

Inventive Principle:
Principle #23Feedback

AI summary

This application relates to an electronic device and an information display method applicable to same, and a medium. The electronic device includes a first screen and a second screen that are an inner screen and an outer screen respectively. The first screen is larger than the second screen. The first screen is a foldable screen. The method includes: detecting a first operation when a plurality of cards are displayed on the second screen in a stacked manner; and displaying, on the first screen in response to the first operation, the plurality of cards displayed on the second screen. A first part of cards and a second part of cards among the plurality of cards are displayed in different positions on the first screen. According to the method disclosed herein, when a user unfolds the relatively large inner screen of the electronic device, the inner screen of the electronic device can display a plurality of cards simultaneously. The plurality of cards can be adjusted based on priority. When the user folds the inner screen and uses the outer screen instead, the outer screen can display the plurality of cards in a stacked manner, and display a card of top priority among the plurality of cards, thereby improving user experience.
