Magnetic Splicing Display Panel Design for Seam Shadow Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional splicing display panels suffer from visible seams that create a dark shadow, affecting the continuity and integrity of the display screen, and existing seam-removing technologies fail to fully eliminate this issue.
Innovation Solution
A splicing display panel design featuring a first and second display module with a third module shielding the seam, utilizing magnetic members for rapid splicing and including a flexible circuit board and mini/micro LED display modules to reduce thickness and improve stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional narrow border splicing design is used, then the display panel can be assembled into large screens, but visible seams create dark shadows that affect display continuity and integrity
Solution Approach 1:
A light guide component is introduced as an intermediary element between the first and second display modules. This light guide redirects ambient light from the seam area away from the viewer's line of sight, effectively eliminating the dark shadow effect while maintaining the narrow border design for large screen assembly
Solution Approach 2:
The patent applies optical interference principles by designing the light guide with specific thickness and material properties that cause constructive and destructive interference of light waves. This changes the optical characteristics at the seam area, transforming the dark shadow into a visually invisible or minimized region
2Productivity
If magnetic members are added to enable rapid splicing, then production efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The magnetic members are integrated directly into the existing display module structures at the seam locations, combining the splicing function with the structural support function. This merging approach enables rapid magnetic assembly while avoiding additional separate components that would increase overall device complexity
Solution Approach 2:
The magnetic members enable the display modules to self-align and self-assemble through magnetic attraction forces, eliminating the need for complex external alignment mechanisms or manual positioning systems, thereby improving productivity without proportionally increasing structural complexity
3Length of stationary object
If the display panel thickness is reduced to achieve thinness, then the panel becomes lighter and more compact, but the magnetic members may increase the thickness
Solution Approach 1:
The patent employs thin-film magnetic members and flexible magnetic adhesive layers instead of bulky magnetic components. These thin-film structures provide the necessary magnetic attraction for rapid splicing while contributing minimal thickness, maintaining the panel's thin and lightweight characteristics
