Transparent Wiring Board With Partial Protective Layer for Low Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile terminal equipment, such as smartphones and smart glasses, the reduction in size and thickness leads to limited space for antennas, resulting in unsatisfactory radio wave sensitivity and a need for protective measures that do not compromise electrical connectability or visibility.
Innovation Solution
A wiring board with a transparent substrate, a mesh wiring layer, a power supply unit, and a protective layer, where the power supply line is connected via an anisotropic conductive film, ensuring protection and reduced visibility of the wiring board in the display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductor mesh layer and power supply unit are covered by a protective layer, then the power supply unit is protected from corrosion, but the wiring board becomes easier to visually recognize due to light reflection
Solution Approach 1:
The protective layer is designed with a light-transmitting property that allows it to be visually inconspicuous while providing protection. The layer material and thickness are selected to minimize light reflection and make the wiring board difficult to visually recognize, thus resolving the contradiction between protection and visibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses deterioration in electrical connectability and corrosion of the power supply unit while maintaining transparency and radio wave transmission/reception functionality, making the wiring board difficult to visually recognize.
Implementation Method 1
a power supply line that is electrically connected to the power supply unit via an anisotropic conductive film containing conductive particles

AI summary
A module includes a wiring board that has a substrate and a mesh wiring layer and a power supply unit and a protective layer, and a power supply line that is electrically connected to the power supply unit via an anisotropic conductive film containing conductive particles. The substrate has transparency. The protective layer covers only part of the power supply unit. The anisotropic conductive film covers a region of the power supply unit that is not covered by the protective layer.
