Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of shrinking electronic device form factors, there is a need for a display module that can maintain an interval between connection patterns without increasing the width of connection members to prevent shorts due to material elution, which is challenging in the narrow mounting spaces of foldable or rollable devices.
Innovation Solution
The solution involves a display module with a first connection member having multiple wires and a display driver integrated circuit, featuring multiple contact points arranged in specific directions on different layers, and a second connection member with laminated layers and wires, allowing for electrical connections without increasing the width of the connection members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the width of connection members is increased to increase the interval between patterns, then the reliability is improved, but the area of stationary object is increased
Solution Approach 1:
The patent applies dimensionality change by transitioning from a single-layer connection member to a multi-layer laminated structure. The first and second connection members are stacked in the vertical dimension, with conductive patterns on different layers that can be spaced apart vertically while maintaining compact horizontal footprint. This allows sufficient interval between conductive patterns without increasing the horizontal width, resolving the contradiction between reliability and mounting space.
Solution Approach 2:
The patent implements nesting by placing one connection member inside or adjacent to another in the vertical stacking arrangement. The first connection member with its conductive patterns is positioned in relation to the second connection member, creating a nested or layered configuration. This nested structure allows multiple conductive paths to coexist in a compact volume with adequate spacing between them, improving reliability without expanding the overall device area.
2Reliability
If the interval between patterns is increased to prevent shorts due to elution, then the reliability is improved, but the width of connection members is increased
Solution Approach 1:
The patent resolves this contradiction by moving the spacing function to the vertical dimension through multi-layer stacking. Instead of increasing horizontal width to create interval between patterns, the invention stacks connection members vertically so that patterns on different layers are separated in the vertical direction. This maintains compact horizontal dimensions while ensuring sufficient interval between conductive patterns to prevent shorts from material elution, thereby improving connection durability.
Solution Approach 2:
The patent employs composite material principles by combining multiple connection members with different conductive patterns into a laminated structure. The first and second connection members form a composite assembly where each layer contributes specific conductive paths. This composite configuration allows optimized spacing between patterns across layers to prevent elution-induced shorts while maintaining overall compact dimensions.
