Electroluminescent Display Sealant Width Measurement via Substrate Scale Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electroluminescent display apparatuses face challenges in accurately measuring the width of transparent sealants, leading to potential malfunctions due to incorrect application and penetration of external impurities.
Innovation Solution
Incorporating a scale pattern on the substrate with discontinuous markings or protrusions along the perimeter, allowing for visual measurement of the sealant width without optical aids, ensuring the sealant is applied at a precise width to prevent impurity penetration and compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealant width is increased to prevent penetration of external impurities, then the sealing effectiveness is improved, but the sealant may penetrate into the display unit and cause malfunction
Solution Approach 1:
The substrate includes a scale pattern with markings that change color or provide visual contrast to indicate the correct sealant width. This allows operators to visually detect and measure the sealant width during application, ensuring the sealant is sufficiently wide to prevent impurity penetration while not excessive to cause malfunction in the display unit
2Device complexity
If the sealant width is measured by the naked eye without measurement markings, then the device complexity is reduced, but measurement precision deteriorates leading to potential malfunction
Solution Approach 1:
The substrate itself provides the measurement function through integrated scale patterns with markings. The substrate serves dual purposes: as the structural base and as the measurement reference tool. This eliminates the need for separate external measurement devices or complex optical systems while providing accurate visual measurement guidance for sealant application
Solution Approach 2:
The substrate is designed to perform multiple functions simultaneously: structural support, electrical connection, and measurement reference. The scale pattern integrated into the substrate allows it to serve as both the mounting surface for display elements and the measurement standard for sealant width control
