Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed pixel density is used in conventional display technologies, then the display structure is simple and stable, but it cannot meet users' diverse application demands for different display definitions
Solution Approach 1:
The patent applies the dynamics principle by making the pixel density adjustable rather than fixed. The display device can dynamically change pixel density distribution according to different display regions and requirements, allowing high pixel density in critical areas and low pixel density in non-critical areas, thus achieving adaptability to diverse display definitions while managing complexity through controlled dynamic adjustment
Solution Approach 2:
The patent implements local quality by applying different pixel densities to different regions of the display. Critical display regions use high pixel density for detailed information, while non-critical regions use low pixel density, optimizing the overall display performance for diverse application demands without uniformly increasing complexity across the entire display
2Measurement precision
If high-resolution display is used to support multiple display modes, then display definition is improved, but power consumption increases and pixels are not fully utilized
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the pixel density parameter based on display requirements. Instead of using a fixed high-resolution display that consumes excessive power, the system changes the pixel density parameter locally and temporally, using high pixel density only when and where needed, thereby reducing overall power consumption while maintaining adequate display definition
Solution Approach 2:
The patent implements partial action by applying high pixel density only to specific critical regions rather than the entire display area. This allows the display to achieve high definition where necessary while using lower pixel density in other regions, fully utilizing available pixels efficiently and reducing unnecessary power consumption from excessive pixel activation
3Adaptability or versatility
If two fixed display sections with different resolutions are integrated, then diverse display definitions are supported, but the display structure becomes complex and inflexible
Solution Approach 1:
The patent applies dynamics by replacing fixed display sections with a dynamically adjustable pixel density system. The display can flexibly change pixel density distribution in real-time based on operational requirements, providing the adaptability of multiple fixed sections while maintaining the flexibility and simplicity of a unified display structure without physical divisions
