Display Panel Overlap Structure for Narrower Splicing Slits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized reflective display applications, such as those used in exhibition halls, suffer from excessive splicing slits due to traditional tiled configurations, which affect visual experience and product competitiveness.
Innovation Solution
A display stacking and splicing structure that overlaps border areas of display panels in a vertical direction, using dummy substrates and optical clear resin layers to fill spaces and reduce the width of splicing slits, while employing a support plate and adhesive layers for structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display panels are spliced directly in a tiled configuration (adjacently along horizontal direction), then the display can be assembled simply, but the splicing slit width becomes excessively large (twice the border area width), affecting visual experience
Solution Approach 1:
The patent transitions from horizontal tiling to vertical stacking configuration. Display panels are arranged in a vertical direction with overlapping border areas, changing the splicing dimension from horizontal to vertical. This dimensional change allows the splicing slit width to be reduced to a single border area width instead of twice the width, thereby improving visual experience while maintaining assembly feasibility through the vertical stacking approach
2Productivity
If display panels are spliced with overlapping border areas in vertical direction, then the splicing slit width is reduced to single-width border area, but the structural complexity increases due to dummy substrates and optical clear resin layers
Solution Approach 1:
The patent introduces dummy substrates and optical clear resin layers as intermediary elements between display panels in the vertical stacking configuration. The dummy substrates fill the spaces created by overlapping border areas, while optical clear resin layers provide optical coupling and structural support. These intermediaries enable the reduced splicing slit width (improving visual experience) while managing the structural complexity through standardized intermediate components
Solution Approach 2:
The patent employs a nested structure where dummy substrates are positioned within the spaces formed by overlapping display panel border areas. The optical clear resin layers are nested between the display panels and dummy substrates, creating a compact vertical stacking arrangement. This nesting approach consolidates multiple elements into a space-efficient configuration, addressing the visual experience requirement while containing structural complexity

AI summary
A display stacking and splicing structure includes plural display panels, plural dummy substrates, at least one optical clear resin (OCR) layer, and a support plate. Each of the display panels has a display area and a border area surrounding the display area. The left side of the border area of one of the display panels overlaps the right side of the border area of another one of the display panels in a vertical direction, thereby forming plural spaces. The dummy substrates are disposed in the spaces. The OCR layer is disposed between one of the display panels and one of the dummy substrates. The support plate is disposed below the display panels.
