Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pixel drive circuit layout is optimized to reduce circuit size, then the display resolution is improved, but the device complexity increases
Solution Approach 1:
The regulating signal line extends in a direction perpendicular to the scan signal line, utilizing a different spatial dimension to route signals. This dimensional change allows the regulating signal line to avoid occupying horizontal space alongside the scan signal line, thereby reducing the overall pixel drive circuit size in the second direction while maintaining functional complexity
2Quantity of substance
If the pixel drive circuit size is reduced, then the pixel density is increased, but the manufacturing precision requirements increase
Solution Approach 1:
The pixel drive circuit is segmented into distinct functional components with clearly defined signal paths. The regulating signal line is separated from the scan signal line in both spatial arrangement and functional purpose, allowing each component to be manufactured and tested independently. This segmentation simplifies the manufacturing process while achieving high pixel density through compact integration
