Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions and components are integrated into the display apparatus, then versatility and performance are enhanced, but device complexity increases
Solution Approach 1:
The display panel is divided into distinct functional regions: a main display area for primary visual output and a component area for housing sensors and other electronic components. This spatial segmentation allows multiple functions to coexist without increasing overall device complexity, as each region is optimized for its specific purpose.
Solution Approach 2:
The patent utilizes the vertical dimension by placing component areas beneath or adjacent to the main display area, allowing sensors and other components to be integrated in three-dimensional space rather than requiring additional planar area. This enables multifunctionality without increasing the device's footprint or structural complexity.
2Ease of operation
If connection wiring is used to connect subpixels spaced apart from pixel circuits, then flexible placement of components is enabled, but light transmittance may be reduced
Solution Approach 1:
Transparent conductive materials serve as intermediaries to connect subpixels in the component area to pixel circuits in the main display area. These transparent wiring structures enable electrical connection while minimizing obstruction to light transmission, thus maintaining high light transmittance despite the flexible placement of components.
Solution Approach 2:
The connection wiring in the component area utilizes transparent or translucent materials that are visually imperceptible or minimally visible, allowing light to pass through effectively. This maintains the optical performance of the display while enabling flexible component placement and connection.
3Area of stationary object
If subpixels are arranged in component areas to display images, then display area is extended, but manufacturing complexity increases
Solution Approach 1:
The display panel employs different subpixel configurations in different regions: the main display area uses standard subpixel arrangements optimized for high-resolution imaging, while the component area uses simplified subpixel structures or fewer subpixels optimized for sensor integration and auxiliary display functions. This local differentiation extends the effective display area while maintaining manufacturing feasibility through region-specific optimization.
