LED Light Board Splicing Structure for Hidden Display Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The obvious splicing seams in LED display screens and LED box bodies formed by splicing multiple light boards affect the display effect due to the visibility of splicing lines, which are a result of the limitations in light board manufacturing processes.
Innovation Solution
A display panel design that includes a back board with multiple light boards, where each light board consists of light beads arranged in an array on a first and second substrate stacked partially, with specific edge regions allowing for seamless splicing by maintaining a preset distance between outermost columns of light beads, thereby blocking the visibility of splicing seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple light boards are spliced together to form LED display screens or LED box bodies, then the display area can be increased, but obvious splicing seams appear that affect the display effect
Solution Approach 1:
The light board is divided into two substrates: a first substrate carrying the light beads and a second substrate positioned away from the light beads. This segmentation allows the substrates to be spliced in a staggered manner, where the first substrate of one light board overlaps with the second substrate of the adjacent light board, effectively hiding the splicing seams and eliminating visible lines while maintaining large display area.
2Ease of manufacture
If light boards are spliced with adjacent edges aligned, then manufacturing is simple, but splicing seams are obvious and affect display quality
Solution Approach 1:
The splicing structure employs asymmetric alignment where the first substrate and second substrate are positioned at different locations. The first substrate of one light board overlaps with the second substrate of the adjacent light board, creating an asymmetric staggered pattern. This asymmetric design effectively blocks splicing seams from being visible while remaining straightforward to manufacture.
3Object-affected harmful factors
If the distance between outermost columns of light beads is reduced to minimize splicing seam visibility, then splicing seam effect is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The second substrate acts as an intermediary element that blocks the splicing seam from view. By positioning the second substrate away from the light beads and having it overlap with the adjacent light board's first substrate, it serves as a visual barrier that conceals the splicing line. This intermediary structure effectively reduces the splicing seam effect without imposing stringent requirements on light bead positioning precision.

AI summary
A display panel and a light board are provided. The display panel includes a back board and a plurality of light boards, each of the plurality of light boards includes light beads and a first substrate and a second substrate that are disposed in a stack. The first substrate includes a first portion and the second substrate includes a second portion that exceeds the first substrate. The first portion of one of the plurality of light boards is stacked with the second portion of an adjacent light board to splice two of the plurality of light boards, and a distance between two columns of the plurality of light beads adjacent to each other and on an outermost side of the two light boards is within a preset range.
