Display Connection Member Structure Against Lifting and Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in preventing lifting and moisture permeation while maintaining aesthetics, particularly in the connection members that connect the display panel and body unit, where the existing designs often compromise on either functionality or appearance.
Innovation Solution
A connection member with a multi-layered structure, featuring a second region with a greater number of conductive layers than the first and third regions, where the uppermost and lowermost layers extend to cover the side portions, including insulating and shielding layers made of black materials, and photo solder resist layers, to reduce resistance and prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection member uses a multi-layered conductive layer structure, then the power and signal supply stability is improved, but the risk of lifting and moisture permeation increases
Solution Approach 1:
The patent applies flexible sealing layers (first and second sealing layers) that conform to the multi-layered conductive structure, creating a protective barrier against moisture and lifting while maintaining the electrical functionality of the connection member
Solution Approach 2:
The connection member uses composite material structures combining conductive layers with insulating and sealing layers, where each layer serves specific functions (electrical conduction, insulation, moisture protection) to simultaneously achieve reliability and prevent harmful factors
2Reliability
If the connection member includes multiple conductive layers for stable power supply, then the functionality is improved, but the aesthetic appearance deteriorates due to visible layer boundaries
Solution Approach 1:
The sealing layers are designed to cover and conceal the boundaries between multiple conductive layers, providing a smooth, uniform surface that hides the complex internal structure while maintaining the necessary electrical functionality
Solution Approach 2:
The patent applies different material properties to different regions: conductive layers for electrical functionality, insulating layers for separation, and sealing layers for aesthetic concealment and protection, with each layer optimized for its specific local function

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.
