Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display splicing methods result in visible gaps and complex assembly processes, affecting display quality and increasing costs, especially as pixel pitch decreases and spliced displays are applied to smaller screens.
Innovation Solution
A spliced display design featuring a transparent substrate with LED modules disposed on its back surface, eliminating the need for tiling frames by bonding LED modules directly to the substrate, thus avoiding visible gaps and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional tiling frame splicing method is used to integrate multiple display units, then large-sized display surface can be achieved, but visible gaps and black lines appear between displays reducing display quality
Solution Approach 1:
The patent merges multiple LED modules onto a single transparent substrate, eliminating the physical separation and tiling frames between modules. This integration approach removes the visible gaps and black lines that occur when displays are spliced using traditional tiling frames, thereby maintaining high display quality across large display surfaces.
2Area of stationary object
If traditional tiling frame splicing method is used to assemble multiple displays, then large display surface can be formed, but assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple LED modules onto one transparent substrate during manufacturing, integrating what would otherwise require complex post-assembly tiling operations. This merging of modules into a single assembly unit dramatically simplifies the assembly process and reduces assembly time while achieving large display surfaces.
3Device complexity
If traditional display splicing method is used, then assembly structure is simple with tiling frames, but visible black lines appear affecting display quality
Solution Approach 1:
The patent merges LED modules onto a continuous transparent substrate, eliminating the need for tiling frames and their associated visible seams. This merging approach maintains structural simplicity while simultaneously improving display quality by removing the black lines that appear at the boundaries of traditionally spliced displays.
