Wireless Combined Display Coordination for Small-Screen Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of implementing combined display of multiple electronic devices with small display sizes while minimizing hardware costs, as existing solutions require dedicated screen splitting devices and complex cabling.
Innovation Solution
A wireless combined display method that utilizes a mobile device to broadcast messages to electronic devices in a local area network, determining orientation and address information to enable one device to control multiple displays without the need for dedicated screen splitting devices or cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated screen splitting devices and complex cabling are used to control combinations of different displays, then combined display of multiple electronic devices can be achieved, but hardware costs are increased
Solution Approach 1:
The patent extracts the screen splitting device from the system, allowing electronic devices to directly control each other's displays through wireless communication. The control function is transferred from a dedicated external device to the electronic devices themselves, eliminating the need for additional hardware while maintaining combined display functionality.
Solution Approach 2:
The patent enables electronic devices to perform multiple functions: they can both display content and control other displays wirelessly. The same device serves as both a display unit and a control unit, eliminating the need for dedicated control devices and reducing overall system complexity.
2Reliability
If dedicated screen splitting devices and cabling are used to control image display, then combined display can be implemented, but the system requires complex cabling and dedicated devices
Solution Approach 1:
The patent replaces the mechanical cabling system with a wireless communication system. Electronic devices communicate display control information wirelessly through wireless communication modules, eliminating the need for physical cables and connectors while maintaining the ability to control multiple displays.
3Device complexity
If small display size electronic devices are used for combined display, then hardware costs are reduced, but visual impact effect and user experience are compromised
Solution Approach 1:
The patent combines multiple small displays into a unified large display area through wireless coordination. By merging the display areas of several small screens, the system achieves a visual impact equivalent to a large display while using only affordable small display devices.

AI summary
A combined display method includes: the mobile device broadcasts a first message in response to receiving a first input, where the first message indicates that the combined display needs to be performed; the mobile device obtains a first image, where the first image includes a first display and a second display, the first display displays first information, and the second display displays second information; the mobile device sends a second message to a first electronic device, where the second message includes the first information, the second information, orientation information of the first display and the second display, a size proportion relationship between the first display and the second display, and a correspondence between the first information and the first display; and the first electronic device controls, in response to receiving the second message, a plurality of electronic devices to perform combined display.
