Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of side wiring manufacturing in display devices reduces panel production yield rates and often damages frameless or narrow-framed panels during splicing.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If side wiring is added to electrically connect driver circuit and light-emitting element, then signal transmission between front and back of panel is achieved, but manufacturing process complexity increases and production yield rate decreases
Solution Approach 1:
The patent transitions from planar side wiring to three-dimensional conductive wire routing through the bezel structure. Conductive wires are embedded within the bezel and extend from the first surface to the second surface, enabling electrical connection without requiring complex side wiring processes on the panel itself.
Solution Approach 2:
The bezel serves as an intermediary structure that houses and routes conductive wires between the driver circuit and light-emitting elements. This mediator approach eliminates the need for direct side wiring on the panel while maintaining electrical connectivity through the bezel's internal wire routing.
2Area of stationary object
If frameless panels are spliced to reduce bezel width, then display area is increased, but panel edges are easily damaged during splicing
Solution Approach 1:
The bezel structure provides a protective framework that cushions and protects panel edges during the splicing process. By maintaining a narrow bezel rather than completely eliminating it, the structure offers mechanical support and protection to vulnerable panel edges while still achieving a near-frameless appearance.
Solution Approach 2:
The patent uses multiple display panels spliced together to create a larger display area, with each panel maintaining its individual integrity protected by the bezel structure. This approach allows expansion of display area while preserving edge protection through the replicated bezel-panel units.
3Shape
If narrow-framed panels are used to reduce bezel width, then aesthetic appearance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The display system is segmented into multiple independent panels, each with its own bezel structure. This segmentation allows each panel to be manufactured and assembled separately with standard precision requirements, then combined to achieve the overall narrow-framed appearance without compounding alignment difficulties.
