Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the entire display panel operates in a high refresh rate mode to provide smooth display, then the display quality is improved, but the power consumption increases significantly
Solution Approach 1:
The display panel is divided into multiple independent areas (first area, second area, third area) that can operate at different refresh rates simultaneously. The processor configures each area with independent timing parameters, allowing high refresh rate for important display regions and low refresh rate for less critical regions, thereby reducing overall power consumption while maintaining display quality where needed.
Solution Approach 2:
Different areas of the display panel are assigned different operation modes based on their specific functional requirements. The first area may operate in a first operation mode with higher refresh rate for critical information, while the second and third areas operate in second operation mode with lower refresh rate, optimizing power consumption according to local display needs rather than applying a uniform refresh rate across the entire panel.
2Adaptability or versatility
If the display panel is bent into a curved surface to achieve novel form factor, then the adaptability is improved, but the power consumption increases
Solution Approach 1:
The curved display panel is segmented into multiple functional areas with independent refresh rate control. By dividing the curved surface into distinct regions that can be updated at different rates, the system maintains the novel curved form factor while reducing the total power consumption compared to updating the entire curved surface at high refresh rates.
3Use of energy by moving object
If different areas of the display panel operate in different operation modes to save power, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The processor is designed with multi-functionality to handle multiple operation modes and timing configurations for different display areas. It can dynamically configure various areas with different refresh rates and update cycles based on system requirements, managing the complexity through a unified control architecture that handles diverse operation modes without requiring separate control circuits for each area.
