Multi-Display Module Control for Automatic Partial Image Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display devices face challenges in automatically adjusting image display when the connection configuration between display modules changes, requiring user intervention to identify and set new positions for partial images.
Innovation Solution
A multi-display device system that includes a control information generation unit to generate and transmit control information based on a lookup table, allowing display modules to automatically identify and display partial images without user intervention, even when the connection configuration changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display modules are sequentially connected in various connection configurations, then the multi-display device can adapt to different arrangements and orders of display modules, but the position of partial images to be displayed varies depending on the connection configuration, requiring user intervention to adjust settings
Solution Approach 1:
The system enables self-service operation by automatically detecting the connection configuration between display modules and autonomously determining the correct partial image positions without requiring user intervention. The control server receives connection configuration information from display modules and automatically generates corresponding image signals, allowing the system to adapt to different arrangements independently.
Solution Approach 2:
The system performs preliminary action by pre-establishing the relationship between connection configurations and partial image positions. The control server stores multiple connection configuration types and their corresponding partial image position mappings in advance, enabling rapid automatic adaptation when the connection configuration changes without requiring real-time user input or manual recalibration.
2Adaptability or versatility
If the connection configuration between display modules changes, then the system can accommodate different physical arrangements, but the position information of partial images must be重新 identified and set
Solution Approach 1:
The control server pre-stores multiple connection configuration types (e.g., sequential, matrix, circular arrangements) and their corresponding partial image position mappings in a database before operation. When the connection configuration changes, the system quickly retrieves the pre-configured position information matching the new configuration, eliminating the need for time-consuming manual re-identification and adjustment of partial image positions.
Solution Approach 2:
The system implements feedback by having display modules automatically transmit their connection configuration information to the control server. The control server receives this feedback, automatically identifies the corresponding connection configuration type, and retrieves the appropriate partial image position information, creating a closed-loop system that rapidly adapts to configuration changes without user intervention.
3Ease of operation
If manual identification and setting of partial image positions is required, then user control over display arrangement is maintained, but the operation becomes complex and time-consuming
Solution Approach 1:
The control server acts as an intermediary between the display modules and the image source. It receives connection configuration information from display modules, automatically determines the appropriate partial image positions based on pre-stored configuration mappings, and generates the corresponding image signals. This intermediary approach simplifies the overall system operation by centralizing the complex control information processing in the server rather than requiring complex local processing in each display module.

AI summary
A multi-display device is configured to display an image, and the multi-display device includes display modules sequentially connected according to a prescribed connection configuration. Each of the display modules may include a signal input unit for acquiring an image signal and control information and a partial image selection unit for obtaining, from the control information, information about the connection configuration of the display modules, wherein each display module selects a partial image corresponding to the display module, from the image signal by referring to a first lookup table based on the information about the connection configuration.
