Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display panel uses uniform high pixel density across all areas, then the image quality is improved, but the power consumption increases
Solution Approach 1:
The display panel applies different pixel densities to different areas based on local requirements. The first area (driver area) uses a first pixel density while the second area (passenger area) uses a second pixel density, optimizing power consumption while maintaining necessary image quality in each zone
2Adaptability or versatility
If the display panel emits light at wide viewing angles, then the visibility to multiple users is improved, but the driver distraction risk increases
Solution Approach 1:
Different optical members with different light emission angles are applied to different areas. The first area uses optical members emitting light within a first viewing angle range (narrower) to prevent driver distraction, while the second area uses optical members emitting light within a second viewing angle range (wider) to enhance passenger visibility
Solution Approach 2:
The display panel is divided into multiple areas with different optical characteristics. By segmenting the display into a driver-facing area and a passenger-facing area, each with customized light emission angles, the system simultaneously achieves driver safety and passenger accessibility
3Illumination intensity
If the display panel increases luminance to improve visibility, then the content visibility is improved, but the power consumption increases
Solution Approach 1:
The display panel applies different luminance levels to different areas based on visibility requirements. The second area (passenger area) operates at a first luminance level for enhanced visibility, while the first area (driver area) operates at a second luminance level, reducing overall power consumption while maintaining necessary visibility
