Image Data Folding for Ultra-Long LED Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display systems struggle to output high-resolution images due to the limitations of the application processor in multimedia player boxes, leading to high costs for player boxes that can handle ultra-long displays, as low-cost options cannot meet the demand for high-resolution video signals.
Innovation Solution
A method and device that process image data by setting the resolution to a maximum value, folding the data to increase the number of rows while reducing the resolution per row, and then splicing these rows back together to achieve the original high-resolution output, allowing for ultra-long display capabilities with standard media player boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the application processor in the multimedia player box outputs high-resolution image data, then the image quality is improved, but the device cost increases due to the limitation of chip performance
Solution Approach 1:
The patent segments the high-resolution image data processing into two parts: the multimedia player box handles data generation at maximum resolution, while the LED display system performs the actual high-resolution rendering through parallel processing of multiple lower-resolution data streams. This segmentation allows each component to operate within its performance limits while achieving the overall high-resolution output.
Solution Approach 2:
The patent implements a nested structure where multiple layers of image data (with resolutions of 1/2, 1/3, 1/4, etc. of the maximum resolution) are processed and combined. Each layer contains a portion of the final high-resolution image, and these nested layers are synthesized to produce the complete high-resolution output, allowing standard processors to achieve beyond their native resolution capabilities.
2Adaptability or versatility
If the multimedia player box uses a high-performance chip to output ultra-long resolution video signals, then the display capability is improved, but the device cost increases
Solution Approach 1:
The patent makes the LED display system universal by enabling it to receive and process multiple different resolution inputs (1/2, 1/3, 1/4, etc. of maximum resolution) and synthesize them into a unified high-resolution output. This multi-functionality allows standard multimedia player boxes to drive ultra-long displays without requiring specialized high-performance chips.
Solution Approach 2:
The patent changes the resolution parameter dynamically by processing image data at different resolution levels (maximum resolution, 1/2, 1/3, 1/4, etc.) and combining these variable-resolution streams. This parameter transformation allows the system to adapt to standard processor capabilities while achieving ultra-long high-resolution display output.
3Manufacturing precision
If the image data is processed at maximum resolution throughout the system, then the image quality is maintained, but the processing load exceeds the capability of standard media player boxes
Solution Approach 1:
The patent applies partial action by processing image data at reduced resolution levels (1/2, 1/3, 1/4 of maximum resolution) through the multimedia player box, which is within its processing capability. The system then combines these partial-resolution streams to achieve the complete high-resolution output, effectively distributing the processing load across multiple manageable tasks rather than requiring one excessive processing operation.
