LED Display Module Frame Assembly for Seam Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display modules face challenges in assembly due to small dot pitches and highly integrated display unit boards, requiring multiple boards to be assembled together, which complicates the process and increases seam formation.
Innovation Solution
A display module assembly system where multiple display unit boards are assembled on a frame with a border and support frame, allowing for easy, reliable, and uniform assembly with reduced seams, using screw connections or bonding, and incorporating a criss-cross support frame for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display unit boards are assembled together to form a display surface, then the display area is increased, but the assembly complexity increases and seams are formed
Solution Approach 1:
The display module is divided into multiple display unit boards, each independently assembled on a frame. Each display unit board contains circuit boards with LED chips, and multiple such boards are arranged to form the complete display surface. This segmentation allows for modular assembly, reducing overall complexity while achieving large display areas.
Solution Approach 2:
Display unit boards are nested within a frame structure that includes a border and support frame. The circuit boards are mounted on the frame, and multiple display unit boards are positioned within the frame's boundaries, creating a nested arrangement that organizes multiple components into a unified structure.
2Area of stationary object
If multiple display unit boards are assembled together, then the display area is increased, but seam formation increases
Solution Approach 1:
A frame structure acts as an intermediary between multiple display unit boards. The frame includes a border and support frame that hold the display unit boards in precise positions, minimizing gaps and seams between adjacent boards. This intermediary structure ensures uniform spacing and alignment, reducing visible seam formation.
3Quantity of substance
If display unit boards are highly integrated with small dot pitches, then the LED density is increased, but the board area is reduced requiring more boards
Solution Approach 1:
The high-density LED display is segmented into multiple smaller display unit boards, each with high LED density achieved through small dot pitches. By distributing the total LED count across multiple compact boards rather than one large board, the design achieves high overall LED density while managing individual board sizes for practical assembly.
4Manufacturing precision
If multiple display unit boards are assembled on a frame, then the assembly uniformity is improved, but the manufacturing process complexity increases
Solution Approach 1:
A standardized frame structure serves as a universal mounting platform for all display unit boards. The frame includes a border and support frame with consistent dimensions and mounting features, allowing any display unit board to be assembled in the same manner. This universality ensures uniform assembly across the entire display while simplifying the manufacturing process through standardization.
