Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular flat panel displays face the challenge of visible dark seams between smaller displays when combined to form a larger display, due to the inherent non-emitting spaces, which affect the aesthetic quality and seamless integration.
Innovation Solution
A light emitting diode (LED) display design featuring a first panel with a substrate, pixel circuits, and light emitting diodes connected via conductive vias, where the edge non-emitting space is minimized to be less than the internal non-emitting space, allowing for seamless alignment and connection of multiple panels without visible seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If modular flat panel displays are combined to form a larger display, then the display size can be increased and manufacturing cost reduced, but visible dark seams appear between the smaller displays
Solution Approach 1:
The patent applies local quality by making the non-emitting space at the edge of the display panel shorter than the non-emitting spaces between pixels within the panel. This creates a localized structural difference at the panel edges that enables seamless tiling when multiple panels are combined, directly resolving the visible seam issue while maintaining the modular approach to large display construction
2Object-generated harmful factors
If the non-emitting space at the edge is reduced to enable seamless panel connection, then the aesthetic quality improves, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the display panel into distinct functional regions: a first region containing pixel circuits and light-emitting diodes, and a second region at the edge with a shortened non-emitting space. This segmentation allows the edge region to be optimized for seamless connection while the main panel area maintains standard pixel structure, balancing manufacturing complexity with aesthetic quality
