Tiling Display Image Positioning via Seam Pattern Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tiling display apparatuses, when the positions of display modules are rearranged to form a free-form screen, the division images often become mismatched, leading to image distortion.
Innovation Solution
A tiling display apparatus that includes a system chip and display modules with seam patterns in border regions, allowing the apparatus to sense module arrangement positions and automatically adjust division image positions based on connection state information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display modules are rearranged to form free-form screen shapes, then screen shape flexibility is improved, but image display accuracy deteriorates due to division image mismatch
Solution Approach 1:
The system performs preliminary detection of module arrangement positions using seam patterns before displaying division images. By detecting the connection states of seam patterns in advance, the system determines the correct arrangement configuration and pre-adjusts division image positions accordingly, ensuring accurate image display even in free-form arrangements
Solution Approach 2:
The system implements a feedback mechanism where division image positions are automatically adjusted based on detected seam pattern connection states. The detection result of module arrangement positions feeds back to the control system, which then modifies division image display positions to maintain image accuracy across various screen configurations
2Manufacturing precision
If manual adjustment of division image positions is performed, then image display accuracy can be improved, but system complexity and operation time increase
Solution Approach 1:
The system achieves self-service by automatically detecting module arrangement positions through seam patterns and autonomously adjusting division image positions without requiring manual intervention. The system serves itself by using its own detection capabilities to correct and optimize its display configuration
Solution Approach 2:
The invention replaces manual mechanical adjustment with an automated detection and control system. Instead of physically moving components or manually configuring images, the system uses electronic detection of seam patterns and software-based position adjustment to achieve the same goal more efficiently
3Loss of time
If automatic adjustment based on seam pattern detection is implemented, then operation time is reduced, but device complexity increases due to additional sensing components
Solution Approach 1:
The seam patterns serve multiple functions: they act as both connection interfaces for joining display modules and as detection markers for determining module arrangement positions. This multi-functionality eliminates the need for separate sensing components, reducing overall device complexity while enabling automatic adjustment
Solution Approach 2:
The invention merges the connection structure (seam patterns) with the detection function. The same physical features used to connect and align display modules are also used by the detection system to identify module positions, combining two functions into a single integrated solution
