Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modular displays with different pixel pitches are used to reduce costs, then manufacturing and installation costs are reduced, but image quality uniformity deteriorates
Solution Approach 1:
The patent applies local quality by dividing the display screen into multiple display areas, each with different pixel pitches optimized for their specific functions. The first display area uses a first pixel pitch while the second display area uses a second pixel pitch, allowing each region to have the appropriate quality level for its purpose, thereby reducing overall manufacturing costs while maintaining necessary image quality uniformity through localized optimization
Solution Approach 2:
The patent changes the pixel pitch parameter across different display areas to resolve the contradiction. By setting different pixel pitch values for different display areas, the system achieves cost reduction through parameter differentiation while maintaining image quality uniformity through controlled parameter transitions and boundary processing
2Manufacturing precision
If high precision modular displays are used, then image quality is maintained, but manufacturing and installation costs increase
Solution Approach 1:
The patent applies local quality by assigning different pixel pitch specifications to different display areas based on their functional requirements. Critical areas receive higher precision displays while less critical areas use lower precision displays, thereby maintaining necessary image quality where needed while reducing manufacturing costs overall
Solution Approach 2:
The patent segments the display system into multiple independent display areas with different technical specifications. This segmentation allows selective application of high-precision displays only where necessary, rather than uniformly across the entire display, thus maintaining image quality in critical regions while reducing overall manufacturing costs
3Manufacturing precision
If uniform high resolution is applied across all display areas, then image quality is consistent, but cost efficiency deteriorates
Solution Approach 1:
The patent implements local quality by setting different resolutions for different display areas according to their specific needs. The first display area uses a first resolution while the second display area uses a second resolution, ensuring image quality consistency within each local area while improving overall cost efficiency through differentiated resolution levels
Solution Approach 2:
The patent changes the resolution parameter across different display areas to achieve both image quality consistency and cost efficiency. By strategically assigning different resolution values to different areas and processing boundary transitions, the system maintains perceived image quality consistency while significantly improving cost efficiency
4Ease of manufacture
If different pixel pitches are used in different display areas, then cost is reduced, but visual seamlessness at boundaries deteriorates
Solution Approach 1:
The patent applies local quality by creating a boundary area with specific processing rules at the interface between different pixel pitch regions. This boundary area receives specialized image processing to ensure visual seamlessness, while the rest of the display areas maintain their differentiated pixel pitches for cost efficiency
Solution Approach 2:
The patent changes the resolution parameter in the boundary area between different display areas to achieve visual seamlessness. By adjusting the resolution and applying image processing techniques specifically in the boundary region, the system maintains cost efficiency through different pixel pitches while ensuring smooth visual transitions

AI summary
An electronic device may receive an image via the transceiver, to be displayed on a display device including a first display area set to a first resolution and a second display area set to a second resolution, set a resolution of a boundary area between the first display area and the second display area to a third resolution based on the first resolution and the second resolution, and transmit the received image and information about the third resolution to the display device. The first resolution may be set based on a first pixel pitch of the first display area. The second resolution may be set based on a second pixel pitch of the second display area. The second pixel pitch may be different from the first pixel pitch.
