Sub-display Screen Sealing via Protruding Joining Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembled screens suffer from poor joint sealing, allowing external dust to enter and contaminate the electronic components, which affects the display quality and service life.
Innovation Solution
A sub-display screen design featuring a fixing piece and a display panel with an assembling piece in the seam region, where the assembling piece seals the gap between the display panel and the fixing piece, and its protruding portion forms a joining portion that seals the seam when adjacent screens are assembled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple display screens are simply composed by overlapping, then the assembly process is simple, but the seam gaps are large allowing dust to enter
Solution Approach 1:
The patent applies preliminary action by pre-forming protruding portions on the display screens before assembly. These protruding portions are designed in advance to interlock and form sealing structures when screens are assembled, preventing dust entry from the outset rather than requiring complex sealing mechanisms during or after assembly.
Solution Approach 2:
The patent segments the sealing function into separate protruding portions that can be independently formed on each display screen. This segmentation allows each screen to contribute to the sealing of its seams with adjacent screens, distributing the sealing responsibility and simplifying the overall assembly process while effectively preventing dust entry.
2Device complexity
If large seam gaps exist between display screens, then the structural assembly is easy, but the joint sealing degree is poor
Solution Approach 1:
The patent implements preliminary action by pre-forming protruding portions on the display screens before assembly. These protruding portions are designed in advance to interlock and form sealing structures when screens are assembled, preventing dust entry from the outset rather than requiring complex sealing mechanisms during or after assembly.
Solution Approach 2:
The protruding portions act as intermediary elements between adjacent display screens. These intermediaries fill the gap between screens and form sealing structures, mediating the connection between screens while ensuring reliable joint sealing without complicating the overall structural assembly.
3Device complexity
If no sealing structure is provided, then the device complexity is low, but the electronic components inside are vulnerable to dust contamination
Solution Approach 1:
The patent applies preliminary action by pre-forming protruding portions on the display screens before assembly. These protruding portions are designed in advance to interlock and form sealing structures when screens are assembled, preventing dust entry from the outset rather than requiring complex sealing mechanisms during or after assembly.
Solution Approach 2:
The protruding portions form flexible sealing structures that can adapt to the assembly process. These flexible sealing elements create protective barriers without requiring complex rigid sealing mechanisms, maintaining low device complexity while effectively protecting electronic components from dust contamination.

AI summary
A sub-display screen, an assembled screen, and a display device are disclosed. The sub-display screen includes a display panel and a fixing piece. The fixing piece is disposed below the display panel for supporting the display panel. A seam region is formed between the fixing piece and the display panel. The sub-display screen further includes an assembling piece arranged in the seam region. A portion of the assembling piece is connected to the display panel and the fixing piece, and seals the gap between the display panel and the fixing piece. Another portion of the assembling piece protrudes from the side of the fixing piece away from the display panel to form a joining portion, and after the sub-display screens are assembled, the joining portions seal the seam regions.
