Solution Overview
Problem
Liquid crystal display devices experience poor picture quality due to distortion and smear caused by frequent changes in inversion systems, particularly when displaying patterns with high contrast, leading to defective display and flickering issues.
Innovation Solution
A device and method for driving liquid crystal display devices that include a timing controller with pattern recognition information, enabling and disabling signals, and detection factors to detect and stop the detection of defective display patterns, allowing for adaptive changes in the inversion system based on image data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inversion system is changed frequently to adapt to different display patterns, then the picture quality for specific patterns is improved, but defective display and flickering occur due to frequent pattern changes
Solution Approach 1:
The patent implements dynamic adjustment of the inversion system based on real-time detection of display patterns. The system transitions from a static inversion mode to a dynamic one that adapts to the content being displayed, changing the inversion period according to detected pattern characteristics while maintaining stability through controlled change thresholds.
Solution Approach 2:
The patent changes the inversion period parameter based on detected display patterns. By monitoring pattern characteristics and adjusting the inversion period accordingly, the system optimizes picture quality for different patterns while preventing excessive changes that would cause flickering or defective display.
2Measurement precision
If the detection sensitivity for defective patterns is increased, then the detection accuracy is improved, but frequent false positives occur causing unnecessary inversion system changes
Solution Approach 1:
The patent implements a feedback mechanism where the detected pattern information is fed back to adjust the inversion system. The system continuously monitors display patterns, compares them against detection thresholds, and adjusts the inversion period based on the feedback, creating a closed-loop control system that balances detection accuracy with system stability.
Solution Approach 2:
The patent performs preliminary detection of display patterns before applying inversion system changes. By pre-analyzing the display content and predicting potential quality issues, the system can proactively adjust the inversion period to prevent defective display rather than reactively responding to already-degraded image quality.
