Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conductive layer structures are used, then manufacturing is simpler, but liquid crystal efficiency is insufficient and fringe field effects reduce display quality
Solution Approach 1:
The conductive layer is divided into multiple segments (first conductive layer and second conductive layer) with different opening patterns. The first conductive layer has first openings while the second conductive layer has second openings, creating a segmented structure that selectively controls electric field distribution to improve liquid crystal efficiency while managing fringe field effects.
Solution Approach 2:
Different regions of the conductive layer structure are given different properties through the layered approach. The first conductive layer and second conductive layer have different opening configurations, allowing local optimization of electric field distribution in different areas of the pixel to enhance overall display quality.
2Illumination intensity
If the aperture ratio is increased for brighter display, then brightness improves, but control over electric field distribution becomes difficult, affecting liquid crystal efficiency
Solution Approach 1:
The invention changes the parameters of the conductive layer structure by introducing multiple layers with different opening patterns and configurations. This allows independent optimization of both aperture ratio and electric field distribution, enabling high brightness while maintaining effective liquid crystal control through the segmented conductive structure.
