Solution Overview

Problem

Conventional liquid crystal displays face display defects due to corrosion risks from water vapor components in the sealant used to bond the array substrate and color filter substrate, affecting the clock metal wire's integrity.

Innovation Solution

A display panel using a microcrystalline metallic glass for the clock metal wire, with a sealant coated over the array substrate and color filter substrate, where the sealant also covers the clock metal wire, reducing water vapor interference and enhancing bonding while maintaining ductility for precise coating.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional sealant is used to bond the array substrate and color filter substrate, then the bonding function is achieved, but the water vapor component in the sealant causes corrosion of the clock metal wire

Engineering Contradiction:

Improvecorrosion resistance of clock metal wireVSAvoidwater vapor interference from sealant

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a protective coating layer as an intermediary between the sealant and the clock metal wire. This coating acts as a barrier that prevents water vapor from the sealant from reaching and corroding the metal wire, thus resolving the contradiction by adding a mediating protective layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs composite material structure by combining the sealant with a protective coating material that has low water vapor permeability. This composite approach allows the sealant to perform its bonding function while the coating material protects against water vapor corrosion.

Inventive Principle:

Principle #40Composite materials

2Reliability

If the clock metal wire is made more corrosion-resistant, then the durability is improved, but the ductility and coating processability may be compromised

Engineering Contradiction:

Improvedurability of clock metal wireVSAvoidcoating process delicacy

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the protective function from the structural function by separating the clock metal wire (providing structural support and signal transmission) from the corrosion protection (provided by the protective coating). This allows each component to be optimized independently for its specific function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protective coating serves as an intermediary layer that provides corrosion resistance without affecting the inherent ductility and manufacturability of the clock metal wire. The coating can be applied delicately while the metal wire maintains its original processing characteristics.

Inventive Principle:

Principle #24Intermediary (Mediator)
