Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If anti-glare surface treatment is applied to the cover plate, then reading comfort and readability are improved, but display quality becomes vague and speckles occur
Solution Approach 1:
The patent applies Fourier transformation to convert spatial domain surface features into frequency domain characteristics, enabling precise control of surface micro-structure parameters. By adjusting frequency distribution parameters of the surface treatment, the patent optimizes the balance between anti-glare performance and display quality, preventing speckles while maintaining readability.
Solution Approach 2:
The patent replaces traditional physical/mechanical surface treatment methods with a mathematical modeling approach using Fourier transformation. Instead of relying on empirical mechanical processes, the invention uses frequency domain analysis to design and control surface micro-structures, achieving more precise control over the anti-glare properties without compromising display quality.
2Object-affected harmful factors
If physical processing method is used on the cover plate, then anti-glare effect is achieved, but speckles cannot be completely prevented
Solution Approach 1:
The patent employs Fourier transformation to analyze the frequency characteristics of surface features, creating a feedback mechanism that allows precise adjustment of surface treatment parameters. By monitoring and adjusting the frequency distribution of surface micro-structures, the system can optimize the anti-glare effect while preventing the formation of speckles, achieving reliable control over both parameters simultaneously.
