Display Wiring Layout With Partition Walls for Bend Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wiring disconnections occur in display apparatuses due to their bent shapes, leading to malfunctions and non-operations.
Innovation Solution
Incorporation of a partition wall with through holes and serpentine patterns in the wiring to prevent disconnection, using organic and black materials for the layers, and surrounding the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wirings are arranged in a bent shape to accommodate display apparatus structure, then the display apparatus can be formed with predetermined angles and compact layout, but wiring disconnection occurs leading to malfunction
Solution Approach 1:
The wiring is divided into multiple segments with through-holes positioned at intervals along its length. These through-holes create segmented reinforcement points that prevent the wiring from disconnecting when bent, allowing the display apparatus to achieve compact angled layouts while maintaining wiring integrity
Solution Approach 2:
Partition walls are positioned beforehand at locations where wiring bends are expected to occur. These partition walls act as protective structures that cushion and support the wiring at critical bend points, preventing disconnection before it can happen during device operation or assembly
2Reliability
If partition wall is added to prevent wiring disconnection, then wiring stability is improved, but device complexity increases
Solution Approach 1:
Partition walls are not implemented uniformly across the entire display apparatus but are strategically positioned only at specific locations where wiring bends occur. This localized approach provides necessary wiring protection while minimizing the overall structural complexity and material usage
