Solution Overview

Problem

Manufacturing of liquid crystal displays often results in particles dropping on metallic wires, leading to flaws and displacement, which can cause poor display effects and increased client complaints due to inadequate protection during the production process.

Innovation Solution

Incorporating a blocker disposed on the metallic wires to prevent particles from dropping and ensure the wires are protected, with the blocker's height exceeding the particles' height to prevent flaws or displacement, and a trapeziform or triangular cross-section to guide particles away from the wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If no blocker is added to protect metallic wires, then the device complexity remains low, but particles drop on metallic wires causing flaws and displacement

Engineering Contradiction:
Improvequality of metallic wiresVSAvoidstructure of metallic wires
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A blocker is introduced as an intermediary component between particles and metallic wires. The blocker physically intercepts particles during the manufacturing process, preventing them from contacting and damaging the data lines and pixel lines. This mediator approach resolves the contradiction by adding minimal structural complexity while significantly improving wire quality and reducing flaws.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The blocker is positioned in advance on the metallic wires before particles can cause damage. By establishing protective coverage beforehand, the system prevents particle contamination and wire displacement during subsequent manufacturing steps such as pressing, thereby improving reliability without requiring complex post-processing solutions.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If a blocker is added to protect metallic wires, then particle damage is prevented, but the device complexity increases

Engineering Contradiction:
Improvepositioning of metallic wiresVSAvoidstructure of metallic wires
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The blocker serves as a protective intermediary that maintains the precise positioning of metallic wires during manufacturing. By physically blocking particles that could cause displacement, the blocker ensures manufacturing precision is maintained without requiring complex positioning mechanisms or processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the blocker height is greater than particle height, then particles are effectively blocked, but the device complexity increases

Engineering Contradiction:
Improveprotection of metallic wiresVSAvoidstructure of metallic wires
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The blocker's height parameter is specifically designed to exceed the height of particles that may be present during manufacturing. This parameter change ensures effective particle blocking and wire protection. The increased height is a simple dimensional modification rather than a complex structural change, thereby improving reliability with minimal impact on device complexity.
