Splicing Display Panel Structure for Seamless Module Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional splicing display panels suffer from visible seams and black edges due to metal traces and sealant usage, which affect 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 a second display module to cover the seam, ensuring a seamless integration and improved flatness, utilizing a driving substrate and LED or OLED light-emitting diodes to cover the seam, and using an optically clear adhesive for stability and uniform light transmission.

Engineering Contradiction Analysis
1Area of moving object
If traditional splicing display panels are formed by splicing multiple display panels, then large size and high resolution are achieved, but visible seams appear between panels affecting visual experience
Solution Approach 1:
A second display module is introduced as an intermediary element to fill the gap between first display modules. This second display module covers the seam and is spliced with adjacent first display modules through their respective accommodating slots, effectively eliminating visible seams while maintaining the large display area.
Solution Approach 2:
The second display module is nested within the accommodating slots formed by adjacent first display modules. The accommodating slots are precisely positioned in the bezel areas of the first display modules, allowing the second display module to fit into the gap and cover the seam, creating a seamless integrated display structure.
2Reliability
If metal traces are arranged in bezel area or sealant is used to encapsulate liquid crystal structure, then display panel structure is completed, but obvious black edges appear
Solution Approach 1:
The second display module is designed to match the color and appearance of the surrounding display areas. By using the same display technology (LCD, OLED, or microLED) and matching the visual characteristics, the second display module effectively camouflages the seam and eliminates the appearance of black edges, making the transition invisible to the human eye.
3Manufacturing precision
If accommodating slot opening is arranged on bezel area side close to seam, then second display module can cover seam effectively, but slot structure becomes more complex
Solution Approach 1:
The display module structure is segmented into first display modules with integrated accommodating slots and a separate second display module. The accommodating slots are precisely positioned in the bezel areas, creating modular components that can be manufactured separately and then assembled. This segmentation allows for optimized manufacturing processes while achieving precise seam coverage.

AI summary
A splicing display panel and a splicing display device are 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. The at least one second display module is arranged in the accommodating cavity, and the second display module covers the seam.
