Shielding Conductor for LCD Static Electricity Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity poses a significant risk of damaging liquid crystal display devices during manufacturing processes, such as scratching wiring and breaking insulating layers, due to defects or friction, which can lead to device failure.
Innovation Solution
A liquid crystal display structure that incorporates a shielding conductor in the peripheral area surrounding the display area, extending along at least one side, to dissipate static electricity and prevent damage to the display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid crystal display is manufactured without a shielding conductor, then the manufacturing process is simpler and cost is lower, but static electricity can damage devices such as thin film transistors and wiring
Solution Approach 1:
A shielding conductor is introduced as an intermediary element between the display area and the peripheral area. This conductor acts as a mediator that intercepts and redirects static electricity away from sensitive components, protecting thin film transistors and wiring without requiring fundamental changes to the display structure.
Solution Approach 2:
The shielding conductor is positioned in advance in the peripheral area surrounding the display area. By having this protective structure in place before static electricity can reach sensitive components, the system prevents damage proactively rather than reacting to damage after it occurs.
2Reliability
If the shielding conductor extends along all sides of the display area, then protection against static electricity is more comprehensive, but the manufacturing process becomes more complex
Solution Approach 1:
The shielding conductor is strategically positioned in the peripheral area rather than uniformly across the entire device. This localized placement provides comprehensive protection where it is most needed (around the display area) while avoiding unnecessary complexity in regions where protection is less critical.
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 shielding conductor effectively disperses static electricity, preventing damage to the display area and ensuring the integrity of the liquid crystal display devices during manufacturing and operation.
Implementation Method 1
a shielding conductor disposed in the peripheral area and extending along at least one side of the polygonal display area
