LED Panel Edge Pixel Protrusion for Tiling Display Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tiling display systems using LED panels face issues with visual image discontinuity due to non-pattern areas at the periphery, which affect display quality and increase maintenance costs.
Innovation Solution
The LED panel design incorporates a substrate with first and second pixels, and protrusion structures with distinct orthogonal projection contours, allowing second pixels to be placed between the display edge and substrate, reducing the visibility of non-pattern areas and enhancing light uniformity when panels are spliced together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED panels are used for tiling display, then setup and maintenance cost is reduced, but visual image discontinuity occurs at the periphery due to non-pattern areas
Solution Approach 1:
The patent applies local quality by differentiating the structure of pixels at different locations. Second pixels at the display edge have a different protrusion structure compared to first pixels in the interior. This localized structural differentiation ensures that edge pixels properly manage light emission at panel boundaries, eliminating the visual discontinuity caused by non-pattern areas while maintaining cost-effective LED panel construction.
Solution Approach 2:
The patent inverts the conventional approach by placing light-emitting elements within the non-pattern area at the display edge rather than confining them strictly to the pattern area. This inversion allows the non-pattern area to contribute to light emission, transforming it from a source of visual discontinuity into an active display region that maintains image continuity across tiled panels.
2Ease of manufacture
If reserved space is provided around the LED panel to meet process requirements, then manufacturing is facilitated, but visual image discontinuity occurs on the display frame
Solution Approach 1:
The patent implements local quality by providing different protrusion structures for interior pixels versus edge pixels. The second pixels at the display edge have protrusions specifically designed to manage light emission at the panel boundary, ensuring that the reserved space does not create visual discontinuity. This localized differentiation maintains both manufacturing feasibility and visual continuity.
3Object-affected harmful factors
If second pixels are disposed between display edge and first pixels with different protrusion structures, then visibility of non-pattern area is reduced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the pixel array into two distinct types: first pixels for the interior and second pixels for the display edge. Each type has specifically designed protrusion structures optimized for its location. This segmentation reduces the visibility of non-pattern areas by ensuring proper light emission control at edges, while the modular nature of the segmentation keeps the added complexity manageable and localized.

AI summary
An LED panel including a substrate, multiple first pixels, multiple second pixels, multiple first protrusion structures and second protrusion structures is provided. The first pixels and second pixels each disposed in a display area of the substrate has at least one light emitting element. The second pixels are positioned on at least one display edge of the display area and positioned between the first pixels and a substrate edge. Each first protrusion structure is positioned on the periphery of the at least one light emitting element of one corresponding first pixel. Each second protrusion structure is positioned on the periphery of the at least one light emitting element of one corresponding second pixel. The orthogonal projection contour of each first protrusion structure on the substrate is different from that of each second protrusion structure on the substrate. A tiling display apparatus adopting the light emitting diode panel is also provided.
