Display Panel Parameter Detection and Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels often experience quality issues due to parameter errors caused by incorrect or artificially modified parameters, leading to product abnormalities after delivery.
Innovation Solution
A detection method and apparatus that uploads and locks original data before delivery, compares it with data read from the delivered panel, and determines whether to deliver based on parameter consistency, feeding back abnormalities to administrators for correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If parameter data is manually modified before delivery, then delivery process can be completed, but product quality deteriorates due to parameter inconsistencies
Solution Approach 1:
The system performs preliminary actions by uploading and locking the first data (original parameter data) before the delivery process begins. This preliminary data locking prevents any subsequent manual modifications, ensuring that the parameter data remains consistent throughout the delivery process while still allowing the delivery to proceed efficiently.
Solution Approach 2:
The system implements feedback by reading the second data (actual parameter data) before coding and comparing it with the locked first data. If inconsistencies are detected, the system provides feedback to stop the delivery process or alert operators, preventing defective products from being delivered while maintaining overall process reliability.
2Reliability
If data is locked and compared before delivery, then product quality is improved, but detection complexity increases
Solution Approach 1:
The system employs self-service by automatically uploading, locking, reading, and comparing parameter data without requiring manual intervention. The detection system performs these operations autonomously, reducing the need for complex manual detection procedures while maintaining high parameter accuracy and reliability.
Solution Approach 2:
The system uses copying by creating a locked copy of the original first data and comparing it with the actual second data. This copying approach simplifies the detection process by allowing direct comparison of data copies rather than requiring complex real-time verification systems, thereby reducing detection system complexity while maintaining reliability.
3Manufacturing precision
If parameter verification is performed before coding, then manufacturing precision is improved, but production time is extended
Solution Approach 1:
The system performs the first data upload and locking as a preliminary action before the actual delivery and coding processes. By preparing the reference data in advance, the verification process during delivery becomes faster and more efficient, reducing the time penalty associated with parameter checking while maintaining manufacturing precision.
Solution Approach 2:
The system replaces manual parameter verification with automated electronic data reading and comparison. This substitution of mechanical/manual processes with automated electronic systems significantly reduces the time required for parameter verification while maintaining or improving manufacturing precision through consistent automated comparison.
Data Source
AI summary
