Multi-Screen Display Mapping for Automatic Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of setting up a multi-screen display system is cumbersome and difficult for users due to the need for manual configuration of display content on each display, especially in large-scale setups, affecting user experience and efficiency.
Innovation Solution
A method where a first electronic device establishes a correspondence between its display regions and the identification information of multiple second electronic devices, allowing automatic display content distribution based on this correspondence, reducing the need for individual user operations and simplifying the configuration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of display content on each display is performed using a control apparatus, then display content can be set on each display, but the setting process becomes cumbersome and user operation becomes difficult
Solution Approach 1:
The system enables automatic configuration where the first electronic device automatically obtains identification information of second electronic devices and establishes correspondence between display regions and devices. This self-service mechanism eliminates the need for manual configuration using a control apparatus, directly resolving the contradiction by making the system configure itself without user intervention.
Solution Approach 2:
The first electronic device performs preliminary actions by automatically obtaining identification information and establishing display region correspondences before actual display content distribution. This preliminary automatic configuration resolves the technical contradiction by preparing the system in advance without requiring cumbersome manual operations during the configuration phase.
2Productivity
If a large quantity of displays need to be disposed manually, then each display can be configured, but the user needs to perform a plurality of operations completing the setting process
Solution Approach 1:
The system automatically configures multiple displays by obtaining their identification information and establishing correspondences without requiring users to perform multiple manual operations. This self-service approach dramatically improves configuration productivity while minimizing the time lost to manual setting operations.
Solution Approach 2:
The system segments the configuration task by obtaining identification information of each second electronic device and establishing individual display region correspondences automatically. This segmentation approach allows efficient handling of large quantities of displays through systematic automatic processing rather than manual operations.
3Reliability
If the first electronic device processes and segments image data for each second electronic device, then correct display content can be sent to each device, but power consumption increases and data transmission becomes complex
Solution Approach 1:
The patent extracts the image data processing task from the first electronic device and transfers it to the second electronic devices. The first device sends complete image data without segmentation, and each second electronic device extracts and displays only its designated portion based on the established correspondence. This extraction approach maintains display content accuracy while significantly reducing power consumption and transmission complexity.
Solution Approach 2:
Instead of the conventional approach where the first device processes and segments image data before sending, this system inverts the process by sending complete image data and letting each second electronic device extract its portion. This inversion resolves the contradiction by maintaining reliability through the correspondence mechanism while reducing energy use and transmission complexity.
4Reliability
If the first electronic device establishes one-to-one data transmission channels to each second electronic device, then data can be transmitted accurately, but signaling overheads increase
Solution Approach 1:
The system merges the data transmission approach by sending complete image data to all second electronic devices through a unified transmission channel rather than establishing separate one-to-one channels. Each receiving device uses its identification information and established correspondence to extract the appropriate display content. This merging approach maintains transmission accuracy while significantly reducing signaling overheads.

AI summary
A display method and an electronic device that relate to the field of terminal technologies are provided. A first electronic device can obtain identification information of a plurality of second electronic devices and establish a correspondence between a display region of the first electronic device and identification information of each second electronic device. Therefore, the second electronic devices can automatically display content in different display regions based on the correspondence. The method includes performing, by the first electronic device, sending a display configuration message, receiving identification information sent by a second electronic device, establishing a correspondence between a display region and the identification information, and sending the correspondence and displayed display content. In this way, the second electronic device can determine, based on the correspondence, a part or all of display content that is in the received display content and that corresponds to the display region.
