Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a liquid crystal display is used, then power consumption is reduced compared to plasma displays, but liquid crystal materials require high driving voltages that can damage the eyes
Solution Approach 1:
The display panel is divided into multiple emission units (first emission unit and second emission unit) that can be independently controlled. Each emission unit corresponds to different color sub-pixels (e.g., red/green and blue/yellow), allowing the system to segment the high voltage application to only specific regions rather than the entire display, thereby reducing overall eye exposure while maintaining display functionality.
Solution Approach 2:
Different emission units are assigned different driving voltages based on their specific requirements. The first emission unit operates at a first driving voltage while the second emission unit operates at a second driving voltage, creating local quality variations in the electrical characteristics. This allows optimal performance for each unit while minimizing the overall harmful voltage exposure to the user's eyes.
2Reliability
If high driving voltage is applied to liquid crystal materials, then display performance is improved, but the high voltage causes eye damage
Solution Approach 1:
The display system dynamically adjusts the driving voltage for different emission units based on real-time requirements. The control circuit selectively applies higher voltage only to specific emission units that need it for optimal performance, while other units operate at lower voltages. This dynamic voltage adjustment maintains display reliability while reducing the overall harmful voltage exposure to users' eyes.
Solution Approach 2:
The system changes the electrical parameters (driving voltage) of different emission units independently. By varying the voltage parameter locally across different emission units rather than applying a uniform high voltage across the entire display, the system achieves the necessary display performance while minimizing the harmful effects on the user's eyes.
3Use of energy by moving object
If the display panel is turned off completely, then power consumption is minimized, but the user cannot access information on the panel
Solution Approach 1:
The display panel is segmented into multiple independently controllable emission units. When power conservation is needed, the system can turn off or reduce voltage to specific emission units while keeping others active, allowing selective information access. This segmentation enables the display to maintain partial functionality with reduced power consumption rather than requiring complete shutdown.
Solution Approach 2:
The display system dynamically adjusts the operational state of different emission units based on user needs and power requirements. Rather than a static on/off state for the entire panel, the system can dynamically activate or deactivate specific emission units, providing flexible information access while optimizing power consumption in real-time.
