Solution Overview

Problem

Existing split-screen display functions in electronic devices are inconvenient, requiring complex procedures to switch tasks within a single split-screen area without affecting the other area, and are cumbersome when displaying partial content in picture-in-picture or floating areas.

Innovation Solution

Implementing a display method that allows switching of a single split-screen area through a multi-task interface by detecting specific operations, such as swipe gestures, to display task lists and switch interfaces independently in each split-screen area, and enabling seamless transitions between partial and full content display in picture-in-picture or floating areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional multi-task interface is used to switch tasks in split-screen display, then task switching is possible, but the operation becomes complex and the other split-screen area is affected

Engineering Contradiction:
Improvetask switching operationVSAvoidoperation procedure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the multi-task interface functionality into separate independent interfaces for each split-screen area. When a user swipes up in the first split-screen area, only that area's task list is displayed, allowing independent task switching without affecting the second split-screen area. This segmentation eliminates the need for complex global multi-task management and simplifies the operation procedure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a global multi-task list is displayed to manage all tasks, then comprehensive task management is achieved, but the independence of individual split-screen areas is lost

Engineering Contradiction:
Improvetask management capabilityVSAvoidsplit-screen area independence
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements local quality by creating distinct task list interfaces tailored to each split-screen area. The first split-screen area has its own dedicated task list that can be accessed and switched independently, while the second split-screen area has its own separate task list. This allows each area to maintain its own task management context, preserving independence while providing comprehensive task management capabilities for the entire device.

Inventive Principle:
Principle #3Local quality

3Area of stationary object

If picture-in-picture or floating area is used to display partial content, then screen space is optimized, but transitioning to full content view is cumbersome

Engineering Contradiction:
Improvescreen space utilizationVSAvoidcontent view transition
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent implements dynamic transitions between picture-in-picture/floating display modes and full-screen display modes. Users can swipe up on the picture-in-picture or floating area to dynamically expand it to full screen, or swipe down to return to the condensed view. This dynamic behavior allows seamless transitions between different content view states, optimizing both screen space utilization and ease of operation.

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments of this application provide a display method, an electronic device, and a storage medium, and relate to the field of electronic device technologies, to improve convenience of using a split-screen display function by a user. The display method includes: displaying a first interface in a first split-screen area, and displaying a second interface in a second split-screen area; detecting a first operation; displaying a third interface in response to the first operation, where the third interface is used to display a task in a first multi-task list corresponding to the first split-screen area, and the first multi-task list includes a first task; detecting a second operation performed on the first task in the third interface; and displaying an interface of the first task in the first split-screen area in response to the second operation.
