Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional display devices use traditional wiring and signal transmission methods, then device configuration is simpler, but image quality deteriorates due to wiring resistance, parasitic capacitance, and noise interference
Solution Approach 1:
The display device is segmented into multiple independent scanning chains, with each chain responsible for scanning a specific region (e.g., half or quarter of the display). This segmentation reduces the wiring length and complexity within each chain while maintaining high image quality through reduced parasitic capacitance and noise interference.
Solution Approach 2:
The patent introduces a new dimensional approach by organizing pixels into multiple scanning chains that scan in different sequences and directions. This multi-dimensional scanning architecture reduces the impact of wiring resistance and parasitic capacitance by distributing the signal transmission paths across different spatial and temporal dimensions.
2Productivity
If display devices use traditional scanning methods, then device configuration is simpler, but productivity deteriorates due to limited frame rates and resolution
Solution Approach 1:
The display is divided into multiple scanning chains that can operate independently and simultaneously. This segmentation enables higher frame rates by parallelizing the scanning process across multiple chains, with each chain handling a portion of the total pixel count, thereby increasing overall productivity without proportionally increasing device complexity.
Solution Approach 2:
The multiple scanning chains operate continuously and simultaneously, ensuring that useful action (pixel scanning and rendering) is maintained across the entire display without interruption. This continuous parallel operation maximizes frame rate and productivity by eliminating sequential bottlenecks in the traditional single-chain scanning approach.
3Loss of information
If display devices use traditional signal transmission, then device configuration is simpler, but loss of information increases due to noise interference and signal degradation
Solution Approach 1:
By segmenting the display into multiple scanning chains with independent signal transmission paths, the patent reduces signal degradation and noise interference in each individual chain. The shorter wiring lengths and reduced parasitic capacitance in each segmented chain minimize information loss, while the overall device complexity is managed through modular architecture.
