Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for eliminating seams between spliced display panels are complex and costly, and optical cover plates used for compensation are heavy and difficult to mount.
Innovation Solution
An optical compensation strip comprising a display cover plate and prisms is applied to the light emitting surface of spliced display panels, refracting light to cover the seam and improve display effects, facilitating mounting and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an LED light bar is disposed between two adjacent sub-display panels to eliminate the seam, then the seam elimination effect is improved, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the light-emitting function from the complex LED light bar system and integrates it directly into the display cover plate through prisms. This eliminates the need for separate LED light bars and driving chips, simplifying the overall structure while maintaining seam elimination capability.
Solution Approach 2:
The patent merges the seam elimination function with the display cover plate by integrating prisms directly into it. This combination eliminates the need for separate components like LED light bars and driving circuits, reducing device complexity and cost.
2Object-affected harmful factors
If an optical cover plate is used for compensation to eliminate seams, then the seam elimination effect is improved, but the weight increases and mounting becomes difficult
Solution Approach 1:
The patent segments the optical compensation function into discrete prisms that are integrated into the display cover plate. This segmentation allows for a lighter, more modular structure compared to a solid optical cover plate, making mounting easier while maintaining seam elimination effectiveness.
Solution Approach 2:
The patent uses a thin, lightweight display cover plate with integrated prisms instead of a heavy solid optical cover plate. This thin-film approach maintains optical compensation functionality while significantly reducing weight and simplifying mounting.
3Object-affected harmful factors
If LED light bars and driving chips are used to eliminate seams, then the seam elimination effect is improved, but the cost increases
Solution Approach 1:
The patent merges the seam elimination function with the display cover plate by integrating prisms directly into it. This eliminates the need for separate LED light bars and driving chips, reducing component count and manufacturing cost while maintaining effectiveness.
Solution Approach 2:
The patent extracts the light-emitting and driving functions from separate expensive components (LED light bars and driving chips) and integrates them into the display cover plate structure, significantly reducing material and manufacturing costs.
