Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If reflective components are used in the display area to enhance light utilization, then light emission intensity is improved, but light leakage at border regions increases
Solution Approach 1:
The backlight module is divided into distinct functional zones: a display area with reflective components for high light emission and a non-display area with reflection-reducing components to prevent light leakage. This spatial segmentation allows each region to be optimized for its specific function without compromising the other.
Solution Approach 2:
Different optical properties are assigned to different regions of the backlight module. The display area uses high-reflectivity components to maximize light output, while the non-display area uses low-reflectivity components to minimize light leakage. This local differentiation resolves the contradiction by allowing high illumination intensity where needed and preventing harmful light leakage where it occurs.
2Object-generated harmful factors
If reflection-reducing components are added to minimize light leakage, then light leakage is reduced, but device complexity increases
Solution Approach 1:
The reflection-reducing components are integrated into the existing backlight module structure, combining multiple functions (light blocking, reflection reduction, and structural support) into unified elements. This merging approach reduces the number of separate components needed and simplifies the overall device architecture while still effectively minimizing light leakage.
3Reliability
If multiple components are added to manage light reflection and distribution, then display quality is improved, but manufacturing complexity increases
Solution Approach 1:
The components in the backlight module are designed with multiple functions. For example, the reflective components serve both to enhance light emission in the display area and to act as structural elements. The reflection-reducing components simultaneously block light leakage and provide mechanical support. This multi-functionality reduces the total number of components needed and simplifies manufacturing processes while maintaining high display quality.
