Bezel-less Display Substrate Routing for Seamless Image Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display apparatuses suffer from a sense of discontinuity due to bezel areas between adjacent display units, which reduces user experience by creating a disjointed image across the connected screen.
Innovation Solution
A display apparatus and multi-display apparatus design that eliminates the bezel area by using a first substrate with a display area extending to the edges, a second substrate with a metal pattern layer and rear insulation layer, and a routing assembly to connect the substrates without a bezel, ensuring a seamless image display across multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bezel is provided to cover the bezel area, then the display panel structure is complete, but the bezel width increases creating visual discontinuity
Solution Approach 1:
The patent removes the traditional bezel structure entirely and replaces it with a routing assembly that directs electrical signals along the edges of the display panel. This extraction of the bezel element eliminates the visual discontinuity while maintaining structural integrity through the routing assembly and substrate extensions.
Solution Approach 2:
The patent extends the substrate into the bezel area and routes signals along the edges, effectively moving the signal transmission path from a two-dimensional plane to a three-dimensional edge-following path. This dimensional change allows the display to achieve seamless appearance by utilizing the edge space for signal routing rather than a traditional bezel.
2Reliability
If a bezel area is eliminated, then visual discontinuity is reduced, but the routing assembly complexity increases
Solution Approach 1:
The routing assembly serves multiple functions simultaneously: it provides structural support for the edge, routes electrical signals along the display perimeter, and enables the substrate to extend into what would traditionally be bezel areas. This multi-functionality reduces the need for separate components and simplifies the overall structure despite the eliminated bezel.
Solution Approach 2:
The patent merges the signal routing function with the structural support function by integrating the routing assembly directly into the substrate structure. This combination eliminates the need for separate bezel structures and simplifies the overall device architecture while achieving the seamless display goal.

AI summary
A display apparatus includes a first substrate including a plurality of pixels provided in a display portion, a second substrate coupled to the first substrate, and a routing portion disposed on an outer surface of the first substrate and an outer surface of the second substrate. The second substrate includes a metal pattern layer connected to the routing portion and a rear insulation layer insulating the metal pattern layer and including an isolation pattern area.
