Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of large-sized display apparatuses and the need for efficient methods to configure multiple small-sized display apparatuses into a single, cohesive multi-display system for applications such as video walls in various settings, while maintaining image quality and reducing financial burdens on consumers and producers.
Innovation Solution
A multi-display apparatus configuration method using wireless communicators with infrared sensors at four sides of each display apparatus, allowing for setting a reference display, determining coordinates, and adjusting image quality, enabling the combination of multiple display apparatuses to form a large-sized display system by selecting and displaying specific areas of an image signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-sized display apparatus is used to provide comprehensive display functionality, then the display area and image quality are improved, but the price and financial burden on customers increase significantly
Solution Approach 1:
The patent divides a large display system into multiple independent display apparatuses that can be configured in a multi-display arrangement. Each display apparatus is a separate unit that can be manufactured and sold individually, reducing the cost burden on customers while maintaining the overall large display area through combination of multiple units.
2Area of stationary object
If multiple display apparatuses are combined to form a multi-display system, then the display area is increased, but the complexity of configuring and coordinating the displays increases
Solution Approach 1:
The patent implements automatic coordinate detection where each display apparatus detects the positions of other display apparatuses in the multi-display system. This feedback mechanism allows the system to automatically determine the spatial relationships between displays and configure the multi-display arrangement without manual intervention, reducing configuration complexity.
Solution Approach 2:
Each display apparatus autonomously performs coordinate detection and participates in the automatic configuration process. The system self-organizes by having each display unit independently detect its position relative to others and automatically determine the overall multi-display configuration, eliminating the need for complex manual setup.
3Adaptability or versatility
If display apparatuses are arranged to form a multi-display system, then the display functionality is enhanced, but ensuring uniformity in display properties across different units becomes difficult
Solution Approach 1:
The patent adjusts display parameters such as brightness, contrast, and color settings for each display apparatus based on its detected position and characteristics. By dynamically changing these parameters, the system compensates for manufacturing variations and environmental differences between units, ensuring uniform display properties across the multi-display system.
