1Area of stationary object
If multiple light-emitting diode display modules are spliced together to form large size displays, then the display area is increased, but gap sizes at module splices increase due to deviations in splicing and module size
Solution Approach 1:
The display system is divided into multiple light-emitting boards, each comprising multiple light-emitting modules. This segmentation allows for standardized manufacturing of individual modules while achieving large overall display area through controlled assembly of segments.
Solution Approach 2:
A second circuit board is introduced as an intermediary component to mount multiple light-emitting boards. This intermediary structure provides a stable platform that facilitates precise positioning and reduces cumulative positioning errors that would otherwise occur when directly splicing modules together.
2Measurement precision
If the resolution is increased, then the display quality is improved, but the visual seamlessness of module edges becomes more challenging to achieve
Solution Approach 1:
The control board and second circuit board are positioned on the reverse side of the light-emitting boards, separating the control electronics from the light-emitting surfaces. This dimensional separation allows for high-resolution light-emitting modules without the physical constraints and visible edges that would result from placing control circuits on the same side.
Solution Approach 2:
Multiple identical light-emitting modules are arranged in arrays on the second circuit board, creating a replicated pattern that achieves high resolution through dense packing of standardized modules rather than requiring each individual module to be uniquely precise.
3Manufacturing precision
If light-emitting boards are mounted on a second circuit board, then module positioning is improved, but the device complexity increases
Solution Approach 1:
The second circuit board serves multiple functions simultaneously: it provides mechanical support for mounting light-emitting boards, establishes precise positioning through its circuit board geometry, and facilitates electrical connections between modules and the control board. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The mounting structure, positioning mechanism, and electrical connection system are merged into a single integrated second circuit board assembly, reducing the number of separate parts and simplifying the overall device architecture while maintaining precise module positioning.
