Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mirror surface display devices with complex structures and high production costs due to multiple-layered silicon oxide and metal films on glass substrates, which complicate the manufacturing process and increase costs.
Innovation Solution
A color filter substrate comprising an underlying substrate with a semi-transparent and semi-reflecting layer, a black matrix, and a color filter layer, where the black matrix and color filter layer are formed on the side opposite to the underlying substrate, allowing for a simpler reflecting layer structure and reduced production costs by isolating the reflecting layer from the external environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple layers of silicon oxide films and metal films are formed on glass substrate to provide oxidation resistance and corrosion resistance, then the protection ability is improved, but the device structure becomes complicated and production cost increases
Solution Approach 1:
The patent combines the protecting layer and reflecting layer into a single integrated layer structure. The protecting layer is formed directly on the glass substrate, and the reflecting layer is formed on the protecting layer, creating a unified multi-functional layer that simultaneously provides both protection and reflection functions, thereby simplifying the overall device structure while maintaining the required protection abilities
Solution Approach 2:
The protecting layer serves multiple functions: it provides oxidation resistance, corrosion resistance, and acts as a base layer for the reflecting layer. By making the protecting layer multi-functional, the patent eliminates the need for separate protection layers and reflecting layers, thus reducing structural complexity while maintaining reliability
2Reliability
If multiple layers of silicon oxide films and metal films are formed on glass substrate to provide oxidation resistance and corrosion resistance, then the protection ability is improved, but the production cost increases
Solution Approach 1:
The patent merges the protecting layer and reflecting layer into an integrated structure where the protecting layer serves as the base for the reflecting layer. This consolidation reduces the number of separate manufacturing steps and material deposits required, thereby lowering production costs while maintaining the necessary protection abilities
Solution Approach 2:
The protecting layer is designed to perform multiple functions including oxidation resistance, corrosion resistance, and serving as a substrate for the reflecting layer. This multi-functionality reduces the total number of layers needed, simplifying the manufacturing process and reducing production costs
3Reliability
If laminating and assembling processes are used for mirror surface display device, then the mirror surface effect is achieved, but the production process becomes complicated and production cost increases
Solution Approach 1:
The patent combines the mirror surface effect generation and protection functions into a single integrated layer structure on the glass substrate. The protecting layer and reflecting layer are formed directly during the glass substrate manufacturing process, eliminating the need for separate laminating and assembling steps, thereby simplifying the manufacturing process while maintaining the mirror surface effect
