Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different display areas use the same drive circuit with uniform control signals, then the device complexity is reduced, but the display performance cannot accommodate different display functions and effects
Solution Approach 1:
The display panel is divided into multiple display areas (first display area and second display area), each with its own dedicated drive circuit (first drive circuit and second drive circuit). This segmentation allows each drive circuit to be independently designed with specific pulse change frequencies tailored to the display functions of its corresponding area, thereby achieving different display effects while managing complexity through modular design.
Solution Approach 2:
Different drive circuits are provided for different display areas, where each drive circuit has locally optimized parameters (different pulse change frequencies) suited to the specific display functions required in each area. This local quality approach enables the upper display area to display dynamic scenes with higher refresh rates while the lower display area displays static scenes with lower refresh rates, optimizing performance for each local region.
2Use of energy by moving object
If different pulse change frequencies are used for different display areas, then the display performance and power consumption are optimized, but the control signal management becomes more complex
Solution Approach 1:
The control signal generation is segmented into separate first control signals and second control signals, each with distinct pulse change frequencies, for the first and second drive circuits respectively. This segmentation enables independent optimization of power consumption for each display area while the controller manages the complexity by generating appropriate control signals for each area based on its specific display function requirements.
