Split-Screen Subsystem Architecture for Independent App Instances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split-screen display technologies in terminals, such as folding screen mobile phones and tablet computers, suffer from mutual interference between different split-screen areas, leading to poor user experience and limitations in running multiple instances of the same application with different accounts.
Innovation Solution
Implementing a subsystem for each split-screen area to run applications independently, decoupling the display logic from the main system framework, allowing independent operation and switching of applications without affecting other areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If applications run on the main system in split-screen mode, then the system structure remains simple, but interfaces in different split-screen areas interact with each other causing poor user experience
Solution Approach 1:
The patent divides the system into multiple independent subsystems, where each split-screen area corresponds to a separate subsystem. This segmentation allows interfaces in different split-screen areas to operate independently without mutual interference, resolving the user experience issue while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent introduces a subsystem management mechanism as an intermediary layer between the main system and individual applications. This intermediary manages the creation, switching, and coordination of multiple subsystems, enabling independent operation of split-screen areas while maintaining overall system control.
2Adaptability or versatility
If the same application runs in multiple split-screen areas, then more functionality is available, but the application cannot run independently in each area
Solution Approach 1:
The patent creates separate subsystems for each split-screen area, allowing the same application to be instantiated independently in each subsystem. This enables the application to run with different accounts or states in different areas simultaneously, achieving both versatility and independent operation through systematic segmentation.
Solution Approach 2:
The patent implements a subsystem copying mechanism where subsystem configurations can be replicated across different split-screen areas. This allows the same application to be copied into multiple independent subsystem instances, each capable of independent operation with different accounts or data states.
3Adaptability or versatility
If users need to log in different accounts simultaneously, then more account options are available, but the current system does not support multiple account instances
Solution Approach 1:
The patent segments the system into multiple independent subsystems, each capable of maintaining separate account login states. This allows users to log in with different accounts simultaneously in different split-screen areas, achieving multi-account support through systematic division while keeping each subsystem's internal structure simple.
Solution Approach 2:
The patent adds a subsystem dimension to the traditional single-system architecture. Instead of managing multiple accounts within one system, the solution creates multiple subsystem instances along a new dimensional axis, allowing parallel account operations without increasing complexity within the original system dimension.

AI summary
The present disclosure relates to a method and an apparatus for split-screen display. The method includes: displaying (S102) a first interface of a first application in a first split-screen area, displaying a second interface of a second application in a second split-screen area, in response to a start instruction for a split-screen function, wherein the second split-screen area is different from the first split-screen area; and displaying (S104) a third interface in the second split-screen area, displaying the first interface of the first application in the first split-screen area, in response to a first operation on the second interface. The third interface is independent from the second application.
