Integrated Gate Driver Sealant for LCD Corrosion Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal displays face challenges in effectively protecting integrated gate drivers from external environmental factors, leading to potential corrosion and performance issues.
Innovation Solution
The integration of a gate driver with distinct regions and a sealant that covers the gate driver and wiring lines, ensuring the gate driver is shielded from external elements by forming a sealant around the pixels and edge portions, with specific distances and alignments to prevent exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the gate driver is integrated into the display panel, then the overall size is reduced and productivity is improved, but the gate driver becomes exposed to external environmental factors causing corrosion and performance issues
Solution Approach 1:
A sealant structure is formed to cover and protect the integrated gate driver and wiring lines from external environmental factors. The sealant acts as a protective barrier that prevents corrosion while allowing the gate driver to remain integrated on the display panel substrate.
Solution Approach 2:
The gate driver is integrated within the display panel structure, and then the sealant is formed to enclose both the gate driver and wiring lines. This nested configuration allows the gate driver to be protected within the overall display panel assembly without requiring separate external housing.
2Volume of moving object
If the gate driver is integrated into the display panel, then the overall size is reduced, but the gate driver becomes vulnerable to external environmental factors
Solution Approach 1:
The sealant is formed as a protective layer that covers the integrated gate driver and wiring lines, creating a barrier against moisture and other environmental factors that could degrade reliability while maintaining the compact integrated design.
Solution Approach 2:
The sealant is formed in advance to prevent exposure of the gate driver to harmful environmental factors before corrosion can occur. This preliminary protective action ensures reliability is maintained throughout the operational lifetime of the display panel.
