Multi-Device Screen Projection Split-Screen Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses can only project content from one mobile device at a time, limiting the ability to simultaneously display projections from multiple mobile devices on the same screen.
Innovation Solution
A display apparatus with a processor that establishes connections with multiple projection devices, determines the type of media resources, and controls the display to show top-level applications and projection contents in split-screen or full-screen modes, allowing multiple windows to display content from different devices simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus allows only one mobile device to project at a time, then the projection quality and control simplicity are maintained, but the ability to display multiple projections simultaneously is lost
Solution Approach 1:
The display screen is segmented into multiple independent windows, with each window capable of displaying content from a different projection device. The system divides the single display area into multiple functional regions, allowing simultaneous presentation of multiple projections without interfering with each other's quality or control mechanisms.
Solution Approach 2:
The projection management system is designed to handle multiple projection protocols and device types universally. The same interface and control mechanisms that work for single-device projection are extended to support multi-device scenarios, allowing the system to adapt to different projection sources while maintaining consistent user experience and control simplicity.
2Productivity
If the display apparatus displays content from multiple projection devices simultaneously, then the productivity and user experience are improved, but the difficulty of managing and controlling multiple projections increases
Solution Approach 1:
Each projection device is assigned to a separate window with independent control capabilities. Users can manage, resize, move, and control the content of each window individually, while the system automatically coordinates between windows to maintain overall system efficiency and reduce manual intervention requirements.
Solution Approach 2:
The system automatically detects and manages multiple projection devices, dynamically allocating windows and coordinating content display without requiring manual configuration. The projection management system self-adjusts to handle device connections, protocol negotiations, and window arrangements, reducing the operational burden on users while maintaining high productivity.
3Area of stationary object
If the display apparatus uses split-screen mode for vertical media resources, then the screen utilization and information display are improved, but the complexity of window management increases
Solution Approach 1:
The system automatically detects the orientation of media resources and applies split-screen configuration accordingly. Vertical media resources trigger a vertical split-screen layout that optimizes screen real estate for portrait-oriented content, while horizontal resources receive horizontal splitting. This localized adaptation to content characteristics maximizes screen utilization without requiring complex manual window management.
Solution Approach 2:
The window management system dynamically adjusts window parameters such as size, position, and orientation based on the characteristics of the projection content. When vertical media resources are detected, the system changes the window arrangement parameters to vertical splitting; when horizontal resources are present, it switches to horizontal splitting. These automatic parameter adjustments optimize screen utilization while keeping management simple through rule-based automation.

AI summary
Disclosed are a display apparatus and a method for controlling screen projections from multiple devices to a same screen. The display apparatus includes: a display and at least one processor configured to execute instructions to cause the display apparatus to: establish a connection with a first projection device; receive projection contents; control the display to show a top-level application of a user interface displayed, in a case that the projection content is vertical media resource; determine whether the top-level application supports split screen display; when the top-level application supports split screen display, the top-level application is displayed in a first window and the projection contents are displayed in a second window; when the top-level application does not support split screen display, the top level application after proportional reduction is displayed in either of the two windows, and the projection content are displayed in the other window of the two windows.
