Adjustable Display Tile Support for Seam Alignment and Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display tile systems face challenges in maintaining uniform seam alignment and accessibility for maintenance, due to tolerances in support structures and limited access methods, which can lead to visual artifacts and safety concerns during servicing.
Innovation Solution
The system employs adjustable support substructures with mechanisms allowing tiles to move parallel to the display plane, creating a gap between tiles for easier access and alignment, using a combination of motor-driven and manual mechanisms, along with alignment mechanisms that allow for precise positioning and self-centering, enabling efficient maintenance and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If clips and receptacles are used to align adjacent display tiles, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The support structure is divided into multiple support substructures, each independently supporting a display tile. Each support substructure can be individually adjusted to compensate for tolerances, eliminating the need for complex clips and receptacles while maintaining alignment precision.
Solution Approach 2:
The support substructures incorporate adjustable mechanisms that allow dynamic positioning of display tiles during assembly and maintenance. This adjustability enables precise alignment without requiring complex fixed alignment features like clips and receptacles.
2Manufacturing precision
If display tiles are tightly assembled with minimal seam width, then visual appearance is improved, but accessibility for maintenance deteriorates
Solution Approach 1:
The adjustable support substructures enable dynamic gap creation between display tiles during maintenance operations. Technicians can temporarily increase the seam width to access components behind tiles, then restore the tight assembly when maintenance is complete, combining visual appearance with maintenance accessibility.
Solution Approach 2:
The support substructure acts as an intermediary mechanism between the display tile and the mounting structure. It provides a controlled interface that allows temporary separation of tiles for maintenance while maintaining tight assembly during normal operation, without requiring permanent gaps.
3Manufacturing precision
If multiple washers are added to adjust LED position, then positioning precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The support substructure incorporates an adjustable positioning mechanism that allows LED board position to be fine-tuned during assembly. This dynamic adjustment capability replaces the need for multiple washer thicknesses, simplifying manufacturing while maintaining positioning precision.
Solution Approach 2:
The adjustable support mechanism enables continuous parameter adjustment of the LED board position relative to the carrier board. This replaces the discrete step adjustments required by washers, improving ease of manufacture while maintaining the ability to achieve precise positioning.

AI summary
The present invention relates to a support substructure for fastening a display tile to a support structure of a tiled display, the support substructure being characterized in that it is linked to the support structure by means of a first mechanism allowing movements of the display tile in a plane parallel to the nominal plane (XY) of the tiled display independently of the presence or absence of adjacent display tiles.
