Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display device is increased, then the display quality is improved, but the power consumption increases
Solution Approach 1:
The patent applies parameter changes by optimizing the voltage amplitude of drive signals within a specific range (8-22 volts) to reduce power consumption while maintaining display quality. This involves adjusting electrical parameters (voltage amplitude) to achieve better energy efficiency without sacrificing the high-resolution display performance.
2Measurement precision
If the number of internal components is increased, then the display resolution is improved, but the load on drive signals increases
Solution Approach 1:
The patent changes the voltage amplitude parameter of drive signals to an optimized range (8-22 volts) to reduce the load on drive signals. This parameter adjustment helps maintain signal transmission efficiency despite the increased number of components required for high-resolution displays.
3Use of energy by moving object
If the operating frequency is increased, then the power consumption is reduced, but the lifespan of the display device is shortened
Solution Approach 1:
The patent optimizes the voltage amplitude parameter within (8-22 volts) to achieve power consumption reduction without requiring excessive frequency increases. This balanced parameter adjustment helps maintain display device lifespan while still achieving energy efficiency goals.
