If liquid crystal molecules are driven by signal voltages of data lines, then grayscale brightness is achieved, but response time is too slow to reach required brightness within one frame time
Solution Approach 1:
The patent applies preliminary action by performing voltage adjustments in advance based on historical display data before the actual display frame is rendered. The system pre-calculates optimal driving voltages for different grayscale areas by analyzing past display performance, so that when the frame needs to be displayed, the liquid crystal molecules are already primed to respond faster, achieving the required grayscale brightness within the frame time without compromising accuracy
Solution Approach 2:
The patent changes the voltage parameter dynamically based on historical display data and grayscale area characteristics. By adjusting driving voltages according to previously observed response patterns, the system optimizes the electrical parameters applied to liquid crystal molecules, enabling faster response times while maintaining precise grayscale brightness control through data-driven voltage selection

If voltage adjustments are made to improve response time, then trailing dynamic pictures are reduced, but display complexity increases due to multiple adjustment processes
Solution Approach 1:
The system applies self-service by automatically analyzing its own historical display data and generating optimization strategies without external intervention. The display device monitors its own performance, identifies trailing picture issues, and autonomously adjusts voltage parameters based on patterns it discovers in its operational history, reducing the need for complex external control mechanisms while effectively minimizing trailing effects
Solution Approach 2:
The patent implements feedback by continuously monitoring display performance and using historical data to inform future voltage adjustments. The system creates a closed-loop control mechanism where past display results feed into subsequent voltage optimization decisions, allowing the system to learn from previous trailing picture occurrences and progressively improve response time while maintaining manageable control complexity through pattern recognition
