Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a component area is added to the display apparatus to integrate additional functions, then the functionality and versatility of the display device is improved, but the boundary visibility between the display area and component area becomes prominent, affecting aesthetics
Solution Approach 1:
The patent applies local quality by introducing an intermediate area with distinct optical characteristics between the main display area and component area. This intermediate area has different light-blocking material arrangements and black matrix configurations compared to the main display area, creating a gradual transition zone that masks the boundary while maintaining functional separation. The selective placement of light-blocking materials and black matrices in specific regions achieves both aesthetic blending and functional clarity.
2Shape
If light-blocking materials and black matrices are added to reduce boundary visibility, then the aesthetic appearance is improved, but the light transmittance in the component area may be reduced, affecting component performance
Solution Approach 1:
The patent segments the light-blocking function into distinct zones: the main display area has full light-blocking materials and black matrices for optimal display contrast, the intermediate area has selective light-blocking elements for boundary masking, and the component area has minimal or no light-blocking materials to maximize light transmittance for component operation. This segmentation allows each zone to optimize its specific function without compromising others.
Solution Approach 2:
The patent implements local quality by varying the density and arrangement of light-blocking materials and black matrices across different areas. The intermediate area uses a reduced concentration of light-blocking elements compared to the main display area, while the component area uses even fewer or no light-blocking materials. This gradient approach maintains aesthetic boundary masking while preserving sufficient light transmittance for component functionality.
3Area of stationary object
If the display area is expanded to occupy more space, then the display quality and user experience are improved, but the area available for additional functions and components is reduced
Solution Approach 1:
The patent resolves the area conflict by transitioning to a three-dimensional arrangement where components are positioned beneath the display area rather than adjacent to it. The component area is located in the vertical dimension under the display panel, allowing the display area to expand horizontally across the full front surface while components are integrated in the depth dimension. This dimensional separation enables both large display area and component functionality without spatial conflict.
