Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall display technologies face inefficiencies in transmitting images to multiple display apparatuses, particularly due to the need for redundancy images, which complicates the process and reduces efficiency when arranging display apparatuses in various configurations.
Innovation Solution
A display apparatus with multiple input and output interfaces and a processor that allows for simultaneous image transmission to multiple display apparatuses without a standardized order, enabling efficient image distribution and allowing for expansion without disconnecting or resetting cable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundancy technology is used to transmit the same image in the opposite direction for stable wall display operation, then reliability is improved, but device complexity and transmission efficiency deteriorate due to transmitting multiple identical images
Solution Approach 1:
The patent divides the wall display system into multiple display apparatuses arranged in a matrix, where each apparatus independently receives and displays a specific region of the image. This segmentation eliminates the need for redundancy transmission while maintaining stability, as each display apparatus operates independently with its designated image portion.
Solution Approach 2:
Each display apparatus in the wall display system is designed with universal functionality to both receive and transmit image signals. This multi-functionality allows any display apparatus to serve as a source or destination, eliminating the need for dedicated redundancy transmission paths and simplifying the overall system architecture.
2Reliability
If multiple identical images (original and redundancy) are transmitted to display apparatuses, then reliability is improved, but transmission efficiency deteriorates
Solution Approach 1:
The image is segmented into multiple regions, with each region transmitted only to the specific display apparatus that needs to display it. This eliminates redundant transmission of identical images while maintaining reliability through the distributed architecture where multiple apparatuses can independently display their assigned regions.
Solution Approach 2:
Instead of transmitting redundant copies of the entire image, the system transmits only the necessary portions of the image to each display apparatus. Each apparatus receives a unique copy of its designated region, eliminating unnecessary data transmission while ensuring reliable display coverage.
3Ease of manufacture
If display apparatuses are arranged in a row for wall display, then ease of installation is improved, but flexibility in configuration deteriorates due to difficulty in transmitting redundancy images
Solution Approach 1:
Each display apparatus is designed with universal input and output interfaces that can connect to any other apparatus in the matrix. This multi-functionality allows the system to accommodate various configurations (rows, columns, matrices) without requiring different transmission methods, thereby maintaining both installation simplicity and configuration flexibility.
Solution Approach 2:
The patent transitions from one-dimensional row arrangement to two-dimensional matrix arrangement, adding another dimension to the configuration. This dimensional expansion allows for more flexible layouts while maintaining simple cable connections through the standardized input/output interfaces of each display apparatus.
