Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process for organic light-emitting display apparatuses has low spatial and manufacturing efficiency due to separate units for testing and etching, leading to defects in subsequent panels during the deposition process before they can be checked.
Innovation Solution
A multi-functional apparatus that integrates testing and etching operations within the same chamber body, utilizing a transfer unit, laser etching unit, and testing unit to efficiently remove unnecessary material and test substrates before encapsulation, reducing the need for separate chambers and minimizing defects in subsequent panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate units for testing and etching are used, then each unit can be optimized for its specific function, but the spatial efficiency decreases and manufacturing efficiency decreases due to large occupied spaces and delayed defect detection
Solution Approach 1:
The patent combines the testing unit and etching unit into a single integrated apparatus that shares a common chamber body and substrate transfer mechanism. This merging allows defect detection and corrective etching to occur in sequence within the same system, eliminating the need for separate standalone units and enabling immediate rework of defective substrates before they proceed to encapsulation.
Solution Approach 2:
The integrated apparatus performs multiple functions including substrate transfer, optical testing for defect detection, and laser etching for corrective processing. The system universally handles both inspection and remediation tasks within a single workflow, increasing manufacturing efficiency by preventing defective substrates from advancing to subsequent encapsulation steps.
2Ease of operation
If separate chambers for testing and etching are used, then operational flexibility is maintained, but spatial efficiency decreases due to large occupied spaces
Solution Approach 1:
The testing unit and etching unit share a common chamber body and substrate transfer mechanism, merging two previously separate chambers into one integrated system. This reduces the total occupied space while maintaining operational flexibility through automated control of the shared resources.
Solution Approach 2:
The single chamber body serves multiple functions by accommodating both the testing unit and etching unit, along with the substrate transfer mechanism. This multi-functional design reduces spatial requirements while preserving operational flexibility through programmable control of different operational modes.
