Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices are vulnerable to damage from electrostatic discharge, which can cause electrostatic breakdown, dust absorption, and electromagnetic interference, and existing structural designs do not adequately address these issues for effective protection.
Innovation Solution
The electronic device incorporates a substrate with specific configurations of wires and semiconductor elements, where the second semiconductor element is positioned to accumulate static electric charges more easily than the first, creating a stronger electric field and directing electrostatic discharge away from the display region, thereby protecting it from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second semiconductor element is designed with narrower widths and closer overlaps with wires in the peripheral region, then electrostatic discharge protection is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by designing the second semiconductor element with non-uniform width characteristics - narrower at certain regions and closer to wires in the peripheral region - to concentrate electric fields specifically where ESD protection is needed, while maintaining standard dimensions in other areas. This localized structural variation enhances ESD protection without requiring high precision across the entire device structure.
Solution Approach 2:
The second semiconductor element acts as an intermediary structure between the wires and the display region. By positioning it closer to the wires with narrower widths, it serves as a mediating element that concentrates and redirects electrostatic charges away from the display region, protecting the main functional area while managing the precision requirements through its intermediate position.
2Reliability
If the second semiconductor element is positioned closer to the wires with narrower widths, then static electric charges are concentrated and electric field is strengthened for ESD protection, but device complexity increases
Solution Approach 1:
The patent introduces local quality variations in the second semiconductor element's width and position relative to wires. This creates localized regions of concentrated electric field strength exactly where needed for ESD protection, while keeping the rest of the device structure relatively simple and uniform, thus managing overall device complexity.
Solution Approach 2:
The patent converts the potentially harmful effect of complex wire-semiconductor arrangements into a beneficial ESD protection mechanism. By deliberately designing narrower widths and closer positions of the second semiconductor element to wires, it creates controlled electric field concentrations that actively protect the device, transforming structural complexity into a protective feature.
