Tiled Display Panel Edge Pattern for Narrow Seam Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with multiple panels arranged in a tiled form, the boundaries between adjacent panels are visually recognizable due to non-display areas, which reduces image quality and aesthetic appeal.
Innovation Solution
The implementation of uneven patterns on the surfaces of adjacent display panels, including convex and concave portions with holes and connection electrodes, to minimize the visual recognition of boundaries by reducing the width of the seam between panels and enhancing attachment security.

Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are connected in a tiled form to increase display area, then the display area is increased, but the boundary between adjacent panels becomes visually recognizable
Solution Approach 1:
The non-display area is extracted and removed from the substrate surface, creating a recessed region that eliminates the visual boundary between panels while maintaining the structural connection for electrical signals
Solution Approach 2:
The connection electrode is nested within the non-display area recess, allowing electrical connection to pass through the boundary region without protruding into the display area, thus maintaining a seamless visual appearance
2Object-affected harmful factors
If the non-display area is reduced to minimize boundary visibility, then the visual recognition of boundary is reduced, but the attachment security between panels is compromised
Solution Approach 1:
The connection structure transitions from a planar arrangement to a three-dimensional configuration with recessed non-display areas, allowing the connection electrode to be positioned vertically within the recess to maintain both visual seamless appearance and mechanical attachment security
3Object-affected harmful factors
If the seam width between panels is reduced, then the visual recognition of boundary is reduced, but the space for connection lines becomes insufficient
Solution Approach 1:
The connection path utilizes the vertical dimension by routing the connection electrode through the recessed non-display area, effectively increasing the available space for connections without expanding the horizontal seam width
