Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable display solutions struggle to meet the need for multiple auxiliary screens and large displays, as they require multiple video output interfaces and complex software installations, and lack functionality for switching between split screen and large screen modes.
Innovation Solution
A multi-screen display system that uses a single transmission line to connect multiple displays with different interface specifications, allowing for control by an external electronic device, and includes a switching member for users to switch between split screen and large screen modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission lines are connected to multiple displays respectively, then each display can be controlled independently, but the computer host requires multiple video output interfaces and multiple video cables
Solution Approach 1:
The patent combines multiple video output interfaces into a single transmission line that can carry multiple video signals simultaneously. The first transmission line includes first and second video output interfaces that are integrated into one cable, allowing multiple displays to be controlled through a single connection to the computer host, thereby reducing interface and cable complexity while maintaining independent display control capability
Solution Approach 2:
The single transmission line is designed to perform multiple functions by incorporating both first and second video output interfaces, as well as a keyboard interface, into one universal cable. This multi-functional transmission line can connect to different types of displays and input devices, eliminating the need for separate cables for each device type
2Device complexity
If USB signal is converted into video signal by Displaylink technology, then video output can be achieved through single USB interface, but software installation is required which is too complex for Windows system host
Solution Approach 1:
The patent replaces the software-based Displaylink conversion system with a hardware-based solution. The transmission line includes dedicated video output interfaces that directly convert and transmit video signals without requiring USB software conversion, eliminating the need for complex software installation while maintaining single-interface connectivity
Solution Approach 2:
The transmission line is designed with built-in video output interfaces that automatically handle signal conversion and transmission without requiring external software assistance. The hardware itself performs the function that previously required software, making the system self-sufficient and easier to operate
3Area of stationary object
If portable display size is increased, then display area is improved, but portability is compromised
Solution Approach 1:
The patent divides the display system into multiple separate display devices that can be individually sized for portability while collectively providing large total display area. The multi-display configuration allows each individual display to remain compact and portable, while the combined display area of multiple screens provides the necessary large workspace
Solution Approach 2:
The patent transitions from a single large display in one dimension to multiple smaller displays arranged in different spatial dimensions and orientations. The displays can be positioned side-by-side, stacked, or at different angles, providing large total display area while maintaining individual display compactness for portability
4Device complexity
If single transmission line is used to control multiple displays, then cable complexity is reduced, but the ability to provide different display modes (split screen or large screen) must be implemented
Solution Approach 1:
The patent implements dynamic display mode switching that allows the system to adapt between different display configurations (split screen mode and large screen mode) based on user needs. The display modes can be changed through a switching member or control interface, providing versatility in display presentation while maintaining the simplified single transmission line connection

Data Source
AI summary
A multi-screen display is disclosed, including a plurality of articulated displays, and one of the displays is signal connected to an external electronic device, so that the external electronic device can be used to control entire display screens of the multi-screen display via only one transmission line. The multi-screen display is configured with a switching member for manipulation by a user to switch display modes of all displays, and the display modes include a split screen mode and a large screen mode, so as to satisfy different usage requirements of the user. The multi-screen display has advantages that displaying screens of all displays via only one transmission line and switching the display modes of all displays in conjunction with the switching member.
