Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single slit angle design is used in liquid crystal display panels, then the device complexity is reduced, but the adaptability to manage multi-level luminance and power consumption requirements is limited
Solution Approach 1:
The pixel electrode is divided into multiple independent subpixel electrodes (first subpixel electrode and second subpixel electrode), each with different initial twist angles. This segmentation allows independent control of each subpixel region, enabling multi-level luminance and power consumption management while maintaining a relatively simple overall structure.
Solution Approach 2:
Different regions of the pixel electrode are assigned different initial twist angles (first initial twist angle for first subpixel electrode, second initial twist angle for second subpixel electrode). This local differentiation enables each region to be optimized for specific luminance and power consumption requirements, enhancing adaptability without significantly increasing device complexity.
2Loss of energy
If higher transmittance is achieved in liquid crystal display panels, then backlight brightness is reduced or power consumption is lowered, but the driving voltage increases leading to higher power consumption
Solution Approach 1:
The patent utilizes different initial twist angles as key parameters to optimize the relationship between transmittance and driving voltage. By selecting appropriate twist angles for different subpixel electrodes, the system achieves optimal balance between transmittance (affecting backlight brightness and power consumption) and driving voltage, thereby reducing overall power consumption without excessive voltage requirements.
