Display Panel Junction Design for Invisible Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display screen resolution increases, the size of elementary bricks must decrease to maintain positioning accuracy, making it difficult to make junctions between bricks invisible, especially since the human eye is more sensitive to rectilinear junctions.
Innovation Solution
A display panel design featuring a support with a receiving surface and connecting portions that include a matrix of pixels arranged in a regular pattern, with pixels missing at specific locations to form junction zones, and a junction opening through the support to separate the peripheral edge from the junction zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of display panels is increased, then the screen resolution is improved, but the junctions between panels become more visible
Solution Approach 1:
The patent extracts the harmful rectilinear pixel arrangement from the connecting portions by removing pixels at specific locations (creating pixel-free locations). This extraction eliminates the straight lines that cause visible junctions while preserving the high-resolution display quality in the main display areas.
Solution Approach 2:
The patent applies different pixel arrangements to different regions: regular matrix organization in main display areas for high resolution, and modified arrangements with pixel-free locations in connecting portions to eliminate visible junctions. This local differentiation resolves the contradiction between resolution and junction visibility.
2Manufacturing precision
If the size of elementary bricks is reduced, then the positioning accuracy of LEDs is improved, but the junctions between bricks become more difficult to make invisible
Solution Approach 1:
By removing pixels at specific locations in the connecting portions, the patent extracts the problematic rectilinear pattern that becomes visible at reduced brick sizes. This allows smaller elementary bricks to be used while maintaining invisible junctions through the modified pixel arrangement.
Solution Approach 2:
The patent introduces asymmetry in the pixel arrangement within connecting portions by creating pixel-free locations at specific staggered positions. This asymmetric modification disrupts the rectilinear patterns that are sensitive to human vision, allowing smaller bricks to be assembled without visible junctions.
3Measurement precision
If the distance between image points at edges of elementary bricks is reduced, then the screen resolution is improved, but the rectilinear junctions become more visible
Solution Approach 1:
The patent extracts the harmful rectilinear alignment by removing pixels at specific locations where straight lines would form at the edges of elementary bricks. This allows reduced dimensional steps (higher resolution) while eliminating the visible rectilinear junctions through strategic pixel removal.
