Solution Overview

Problem

User experience is interrupted during cross-application redirection in mobile terminals due to the interface displaying only the content of the new application, leading to a reduction in user experience.

Innovation Solution

A display method for electronic devices with foldable displays that allows simultaneous display of content from both the original and temporary applications based on the device's physical form, using techniques such as floating, split-screen, or both on the home screen, ensuring continuous viewing without form changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a common floating window is used to implement parallelism of multiple tasks, then task parallelism is achieved, but user experience is interrupted during cross-application redirection because the interface displays only content of the new application

Engineering Contradiction:
Improvetask parallelismVSAvoiduser experience continuity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display interface is segmented into multiple regions, with each region displaying content from different applications. The original application content is retained in one region while the new application content is displayed in another region, allowing both applications to be visible simultaneously and eliminating the need to completely switch between applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a traditional floating window that overlays the entire screen, the patent divides the display area into multiple spatial regions. This dimensional approach allows content from multiple applications to coexist in different areas of the screen, providing continuous access to both applications without interruption.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the interface displays only content of the new application during cross-application redirection, then the new application content is fully visible, but the original application content is lost, leading to user experience interruption

Engineering Contradiction:
Improvenew application content visibilityVSAvoidoriginal application content
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

The patent merges the display areas of multiple applications by dividing the screen into multiple regions. Each region displays content from a different application, allowing users to view and interact with multiple applications simultaneously without losing content from any single application.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Different regions of the display screen are allocated to different applications, with each region optimized for its specific application content. This local allocation ensures that each application's content is fully visible in its designated region while other applications remain accessible in other regions.

Inventive Principle:
Principle #3Local quality

AI summary

A display method and an electronic device are disclosed. The method is for a first electronic device having a foldable display displaying a first interface of a first application. The method includes: detecting, on the first interface, a first operation of starting a temporary application by a user, where the first operation does not change a physical form of the first electronic device, and the physical form includes a folded state and an unfolded state; and displaying, in response to the first operation, a second interface based on the physical form of the first electronic device, where the second interface includes the first interface and an interface of the temporary application.
