Splicing Screen LED Layout for Uniform Seam Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display performance of existing splicing screens is poor due to suboptimal arrangement of LED chips in the splicing areas, leading to inconsistent and inferior image quality.
Innovation Solution
A splicing screen design featuring display modules with packaged LED units in the display area and additional LED chips in the splicing area, where the distances between these chips are carefully arranged to ensure uniformity and alignment, allowing for precise control over LED chip spacing without packaging constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packaged LED units are used in the display area, then assembly efficiency is improved, but display performance at splicing parts deteriorates
Solution Approach 1:
The display module is segmented into two distinct areas: display area using packaged LED units for efficient assembly, and splicing area using individual LED chips for precise alignment. This segmentation allows each area to be optimized independently for its specific function.
Solution Approach 2:
Different types of LED structures are applied to different locations: packaged LED units are used in the display area where assembly efficiency is prioritized, while individual LED chips are used in the splicing area where precision and uniformity are critical. The splicing area also features adjusted pitch dimensions to optimize display performance at boundaries.
2Manufacturing precision
If individual LED chips are used in splicing areas, then display uniformity is improved, but assembly complexity increases
Solution Approach 1:
The display module is segmented into two distinct areas: display area using packaged LED units for efficient assembly, and splicing area using individual LED chips for precise alignment. This segmentation allows each area to be optimized independently for its specific function.
Solution Approach 2:
The patent combines two different LED implementation approaches (packaged units and individual chips) within a single display module design, merging the advantages of both methods: efficient assembly in the display area and precise uniformity in the splicing area.
