Spliced Display Module Positioning for Small-Pitch Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spliced display screen technologies face misalignment issues during installation, particularly for small-pitch displays below 1.5 mm, leading to pixel dislocation and inaccurate alignment, which complicates deployment and increases costs due to the need for complex box bodies and precise assembly methods.
Innovation Solution
A spliced display screen design featuring positioning mechanisms with pins and grooves, combined with elastic structures, that allow for precise alignment and secure attachment of adjacent modules without the need for a box body, enabling accurate splicing and simplified assembly by using positioning pins that rotate within grooves and return to their initial position via elastic structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex box bodies and precise assembly methods are used to achieve accurate alignment, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the positioning function from the complex box body structure and implements it through simple positioning pins and grooves integrated directly into the display modules. This eliminates the need for separate box bodies while maintaining alignment accuracy through the pin-groove engagement mechanism.
Solution Approach 2:
The positioning pins automatically engage with grooves when modules are brought together, and the elastic structures automatically push the pins back into grooves if they become disengaged. This self-correcting mechanism ensures accurate alignment without requiring complex external positioning systems or precise manual assembly.
2Ease of operation
If positioning mechanisms with elastic structures are used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The elastic structures connected to positioning pins create a self-service mechanism that automatically guides modules into correct alignment and maintains engagement. The elastic push ensures pins remain engaged with grooves without requiring external fastening mechanisms, simplifying both assembly and disassembly operations.
Solution Approach 2:
The positioning mechanism incorporates dynamic elastic structures that allow the pins to move flexibly during assembly and maintain constant contact with grooves. This dynamic capability enables easy module replacement and reconfiguration while ensuring reliable positioning, transforming a static rigid connection into an adaptable system.
