Spliced Display Scaling for Seamless Image Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display technologies is that splicing screens with different resolutions and dot spacings results in inconsistent image scaling ratios, leading to discontinuous and visually unacceptable displays with seams, dark lines, or bright lines at the splicing edges.
Innovation Solution
An image display method that determines the image scaling ratio and display control parameters for each screen body based on the resolutions and dot spacings of multiple screen bodies, ensuring identical scaling ratios across all screens, thereby maintaining image continuity and consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple screen bodies with different resolutions and dot spacings are spliced to adapt to various stage shapes, then the adaptability of the display screen is improved, but the image scaling ratio consistency deteriorates, causing discontinuous images and visual defects
Solution Approach 1:
The patent applies local quality by determining image scaling ratios and display control parameters individually for each screen body based on its specific resolution and dot spacing characteristics. Each screen body receives customized processing parameters rather than a uniform approach, allowing the system to accommodate diverse screen configurations while maintaining overall image consistency across the spliced display wall.
2Device complexity
If simple division of input source according to screen body resolution is used, then the device complexity is reduced, but the image continuity deteriorates due to inconsistent scaling ratios and sharp changes at splicing edges
Solution Approach 1:
The patent implements parameter changes by dynamically calculating and adjusting image scaling ratios and display control parameters for each screen body according to its specific resolution and dot spacing. This parameter adaptation ensures smooth transitions at splicing edges and maintains image continuity, replacing the simple fixed division method with a more sophisticated but still computationally efficient parameter-based approach.
3Adaptability or versatility
If screen bodies with different dot spacing specifications are spliced, then the flexibility of display configuration is improved, but the visual effect deteriorates due to more serious inconsistent image scaling ratios
Solution Approach 1:
The patent addresses different dot spacing specifications by applying local quality principles - each screen body's display control parameters are individually determined based on its specific dot spacing and resolution characteristics. This localized parameter adjustment ensures that each screen body contributes appropriately to the overall image, maintaining consistency even when combining screens with varying dot spacing specifications.
