Splicing Display Panel Structure for Seamless Module Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional splicing display panels suffer from visible seams due to the arrangement of metal traces and sealants in the bezel area, which affect the visual experience and display quality, especially in large outdoor displays.
Innovation Solution
The implementation of a splicing display panel design that includes accommodating slots in the bezel area of adjacent display modules, allowing for a second display module to cover the seam, and the use of an optically clear adhesive to fill the seam, ensuring a seamless connection and improved flatness of the light-emitting surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional display panels use metal traces in bezel area and sealant to encapsulate liquid crystal structure, then the display panel can be manufactured with basic functionality, but obvious black edges appear at the edge of the display panel
Solution Approach 1:
The patent extracts and removes the black matrix and sealing regions from the edge area of the display panel. By taking out these components that cause black edges, the display panel achieves edgeless display effect while maintaining basic functionality through alternative structural arrangements.
Solution Approach 2:
The patent moves the functional elements (metal traces, sealant) from the two-dimensional edge plane to the three-dimensional space by extending them into the display area or repositioning them on the inner surface of the bezel, thereby eliminating their visual impact on the edge while preserving their functional roles.
2Area of stationary object
If traditional splicing display panel is formed by splicing multiple display panels, then large size display can be achieved, but seams appear between adjacent panels which affect visual experience
Solution Approach 1:
The patent merges adjacent display panels by eliminating the physical separation (seams) between them. Through edgeless design and precise alignment techniques, multiple panels are combined into a unified visual surface, creating a seamless large-area display while maintaining the modular structure for manufacturing feasibility.
3Device complexity
If accommodating slot opening is arranged away from the seam, then the structure is simpler, but step difference appears between first display module and second display module affecting flatness
Solution Approach 1:
The patent applies local quality by positioning the accommodating slot opening specifically at the seam location rather than uniformly distributing openings. This localized arrangement allows the opening to be hidden within the seam region, eliminating step differences and maintaining flatness while keeping the overall structure relatively simple.

Function Achieved in This Case
This solution achieves seamless splicing, enhances the utilization rate of the screen, improves display quality by eliminating dark shadows at the seam, and ensures a flat and continuous light-emitting surface, thereby addressing the issue of visible seams in traditional splicing display panels.

AI summary
A splicing display panel is provided. The splicing display panel includes at least two spliced first display modules and at least one second display module. There is a seam between two adjacent first display modules. A portion of the first display module corresponding to a bezel area is provided with an accommodating slot. The accommodating slot of one of the first display modules is spliced with the accommodating slot of another one of the first display modules to form an accommodating cavity.
