Display Connection Member Layer Layout Against Lifting and Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in preventing lifting and moisture permeation while maintaining aesthetics and ensuring reliable connectivity between the display panel and the body unit.
Innovation Solution
A connection member with a multi-layered conductive structure, featuring a first region, a second region with a higher number of conductive layers, and a third region, where the uppermost layer of the second region extends to the third region, and the lowermost layer of the third region extends to the second region, effectively covering the side portions and preventing exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-layered conductive structure is used to improve electrical connectivity and reduce resistance, then the reliability of power and signal supply is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The connection member is divided into three distinct regions (first, second, and third regions) with varying numbers of conductive layers. The second region has a greater number of conductive layers than the first and third regions, allowing optimized electrical connectivity in different areas without uniformly increasing complexity throughout the entire structure.
Solution Approach 2:
Different regions of the connection member have different numbers of conductive layers tailored to their specific functional requirements. The second region, which likely requires better electrical connectivity, has more conductive layers, while the first and third regions have fewer layers, optimizing both performance and complexity locally rather than globally.
2Reliability
If the uppermost layer of the second region extends to the third region and the lowermost layer of the third region extends to the second region to cover side portions, then lifting and moisture permeation are prevented, but the manufacturing precision requirements increase
Solution Approach 1:
The first layer (uppermost layer of the second region) is designed to extend into the third region, and the second layer (lowermost layer of the third region) is designed to extend into the second region, creating overlapping coverage before potential lifting or moisture intrusion can occur. This preliminary extension of layers provides a buffer zone that prevents edge exposure.
Solution Approach 2:
The layers are arranged in a nested configuration where the first layer extends into the third region and the second layer extends into the second region, creating an interlocking structure. This nesting arrangement ensures that side portions are covered by multiple layers, preventing lifting and moisture permeation through redundant coverage.
3Shape
If the first layer and second layer extend beyond their respective regions to cover side portions, then aesthetics are improved by concealing internal layers, but the material usage and device complexity increase
Solution Approach 1:
The first layer and second layer serve multiple functions: they provide electrical connectivity as conductive layers, offer moisture protection by covering side portions, and enhance aesthetics by concealing internal structures. This multi-functionality allows a single structural modification to achieve multiple benefits without proportionally increasing material usage.
Solution Approach 2:
The protective and aesthetic functions are merged into the existing conductive layers (first layer and second layer) rather than adding separate protective coatings or aesthetic coverings. By extending these existing layers to cover side portions, the patent combines structural, protective, and aesthetic roles into a unified design.

AI summary
A connection member includes a first region, a second region, and a third region, where a number of conductive layers in the second region is greater than a number of conductive layers in the first region and is greater than a number of conductive layers in the third region, a first layer, which is an uppermost layer of the second region, extends to the third region, a second layer, which is a lowermost layer of the third region, extends to the second region, and a side portion of the second region at a boundary between the second region and the third region is covered by the first layer and the second layer.
