Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a black matrix is added to reduce external light reflection, then visibility is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent combines the light blocking function with existing structural elements (sensory electrode patterns, connection lines, and conductive patterns) that are already present in the display device. By making these existing components serve dual purposes (electrical function + light blocking), the patent avoids adding separate black matrix structures, thereby improving visibility while maintaining device simplicity
Solution Approach 2:
The patent makes existing components multi-functional by designing sensory electrodes, connection lines, and conductive patterns that simultaneously perform their electrical functions and provide light blocking. This eliminates the need for dedicated black matrix structures, resolving the contradiction between improving visibility and reducing device complexity
