Display Module Connector Extension for ESD Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing integration of electronic components in compact electronic devices leads to reduced separation distances, making them susceptible to electrostatic discharge (ESD) phenomena, which can cause damage and malfunction due to accumulated electric charges.
Innovation Solution
A display module design that includes a flexible printed circuit board with a connecting member featuring an extension part to cover electronic components, reducing the likelihood of ESD by providing an additional path for electrical signals and potentially grounding excess charges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electronic components are integrated more densely to reduce device size, then device compactness is improved, but susceptibility to electrostatic discharge increases
Solution Approach 1:
A connecting member with an extension part is introduced as an intermediary element between the flexible printed circuit board and the housing. This extension part provides an additional discharge path for electrostatic charges, mediating the ESD protection function while maintaining the compact integrated structure of the electronic device
2Length of moving object
If separation distance between electrical objects is reduced to save space, then device compactness is improved, but ESD damage risk increases
Solution Approach 1:
The connecting member extends in a direction perpendicular to the main circuit board plane, creating a three-dimensional discharge path. This dimensional extension allows ESD protection without increasing the two-dimensional footprint or separation distance on the circuit board, thus maintaining compactness while reducing ESD damage risk
