Tiled Display Alignment Structure for Small-Seam Tile Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aligning and fastening display tiles in tiled displays face challenges such as requiring extensive manipulation, risking damage to fragile light emitting elements, and lacking simple and reliable fastening means that can be accessed from the front, especially when seam sizes are small.
Innovation Solution
An intermediary support structure with fastening means distributed along one or two sides of the display tile, extending beyond its perimeter, and accessible from the display side, allows for precise alignment and fastening without direct contact with the display surface, using temporary magnets for assembly and permanent or semi-permanent joints for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fastening means are used to align display tiles, then alignment precision can be achieved, but the risk of damaging fragile light emitting elements increases due to extensive manipulation and shocks between adjacent tiles
Solution Approach 1:
The patent introduces an intermediary alignment mechanism consisting of alignment pins and alignment holes that mediate between the fastening means and the display tiles. The alignment pins fit into alignment holes positioned away from the display surface, allowing precise positioning without direct contact with fragile LEDs. This intermediary system transfers alignment forces through the tile structure rather than applying them directly to vulnerable components.
Solution Approach 2:
The fastening system is segmented into separate functional components: alignment pins for positioning, fastening means for securing, and intermediary elements that distribute forces. By separating alignment functions from fastening functions and positioning critical alignment features away from the display surface, the system reduces stress concentration on fragile light emitting elements during assembly.
2Manufacturing precision
If seam size is reduced to achieve higher display quality, then visual appearance improves, but access to fastening means becomes impossible when seam is smaller than fastening means dimension
Solution Approach 1:
The patent resolves the access problem by changing the spatial dimension of fastening operations. Instead of accessing fastening means through the lateral seam between adjacent tiles, the system provides access from the rear side of the display structure. This dimensional shift allows maintainers to reach fastening components without requiring lateral clearance, enabling seamless tile edges while maintaining serviceability.
Solution Approach 2:
The patent introduces intermediary access structures such as rear access panels or extended fastening mechanisms that mediate between the maintainer and the fastening means. These intermediaries provide the necessary access pathway through the rear side, allowing fastening operations on tiles with minimal seam dimensions without compromising ease of operation.
3Ease of operation
If fastening means are positioned to allow access from front for maintenance, then ease of operation improves, but the fastening means cannot be positioned close enough to achieve small seam sizes
Solution Approach 1:
The patent shifts the access dimension from lateral (through seam) to longitudinal (from rear side). By positioning fastening means accessible from the rear, the system decouples the seam size constraint from the access requirement. Maintainers can service tiles by accessing fastening components from behind the display structure, allowing seam dimensions to be minimized for visual quality without compromising maintenance accessibility.
