Multi-Mode Display Sharing for Concurrent Source Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in integrating display outputs from multiple information handling systems, such as portable and personal mobile devices, into a single display device, as existing technologies lack efficient methods for concurrent display of graphical content from different sources.
Innovation Solution
A multi-mode display device detects connections with primary and secondary display sources, sends display mode data, receives user-selected display mode settings, and outputs display data from each source to designated regions on the same screen, enabling simultaneous display of multiple inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device supports multiple display sources simultaneously, then the adaptability and versatility of the display device is improved, but the device complexity increases due to the need for multiple connection interfaces and display mode management
Solution Approach 1:
The display device is designed with multiple connection interfaces (HDMI, DisplayPort, USB-C) that support both portable and stationary display sources simultaneously. The processor can handle multiple display protocols and formats, enabling the single display device to serve multiple functions and accommodate various display sources without requiring separate dedicated devices for each source type.
Solution Approach 2:
The processor acts as an intermediary that receives display signals from multiple sources, manages display mode negotiations, and coordinates output to different display regions. It mediates between the primary and secondary display sources, handling the complexity of simultaneous display operations, mode switching, and region allocation internally while presenting a unified interface to users.
2Productivity
If the display device outputs to multiple display regions simultaneously, then the productivity and usability are improved, but the ease of operation decreases due to the need for manual display mode selection and configuration
Solution Approach 1:
The display device performs preliminary actions by automatically detecting the presence and type of connected display sources, pre-negotiating display modes, and pre-configuring display regions before user input is required. The processor proactively manages display mode switching and region allocation based on detected source types, reducing the need for manual configuration and making the system easier to operate while maintaining high productivity.
3Loss of time
If the display device supports concurrent output from multiple sources, then the loss of time is reduced by eliminating the need to switch displays, but the device complexity increases due to simultaneous signal processing requirements
Solution Approach 1:
The display device segments the display screen into multiple independent display regions, each dedicated to a specific display source. The processor handles each region's signal processing independently, allowing concurrent output from multiple sources without requiring time-based switching. This segmentation enables simultaneous display of multiple sources while managing processing complexity through spatial separation of display content.

AI summary
A multi-mode display device may, responsive to a user-selection, divide a display region into different regions corresponding to display data received from different user devices, such as a primary information handling system and a secondary portable information handling system. First display data received from the primary information handling system may be output to a first display region and second display data received from the secondary portable information handling system maybe output to a second display region.
