Engineering Contradiction Analysis
1Duration of action of moving object
If the display is operated for extended periods of time, then the display can deliver diverse contents to the user, but heat accumulates and causes temperature increase leading to voltage imbalance and image distortion
Solution Approach 1:
The system performs preliminary temperature compensation by measuring the temperature and selecting an appropriate cancellation algorithm before the voltage imbalance significantly affects display quality. The processor proactively adjusts the voltage compensation based on predicted temperature conditions, preventing distortion rather than correcting it after occurrence.
Solution Approach 2:
The system changes the voltage compensation parameters dynamically based on temperature conditions. By selecting different cancellation algorithms corresponding to different temperature ranges, the system adapts the display voltage parameters to compensate for temperature-induced voltage imbalance, maintaining display quality across varying temperatures.
2Reliability
If the temperature increases, then the display continues to operate, but voltage imbalance occurs causing image distortion and afterimages
Solution Approach 1:
The system implements a feedback mechanism where the temperature sensor continuously monitors display temperature, and the processor uses this feedback to dynamically select and apply the appropriate cancellation algorithm. This closed-loop control ensures that voltage compensation is continuously adjusted based on actual temperature conditions, maintaining both reliability and precision.
Solution Approach 2:
The system transitions from static voltage compensation to dynamic temperature-dependent compensation. By making the cancellation algorithm selection dynamic and responsive to temperature changes, the system maintains image precision across varying operational conditions while ensuring reliable continuous operation.
3Device complexity
If a fixed voltage is applied to the display, then the display structure is simple, but temperature changes cause voltage imbalance and distortion
Solution Approach 1:
The system segments the temperature operating range into multiple intervals, with each interval having a corresponding cancellation algorithm. This segmentation approach divides the complex temperature compensation problem into manageable discrete ranges, maintaining relatively simple control logic while achieving precise compensation across the full temperature spectrum.
