Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If resolution of display apparatus is increased, then display quality is improved, but opening ratio is decreased and luminous quality is lowered due to increased loads on wirings
Solution Approach 1:
The pixel electrode is divided into multiple segments (first pixel electrode segment, second pixel electrode segment, third pixel electrode segment) arranged in different directions. This segmentation allows the wiring structure to be optimized for each segment, reducing the overall load on individual wirings while maintaining high resolution display quality.
Solution Approach 2:
The pixel electrode segments are arranged in different directional orientations (first direction, second direction, third direction). This multi-dimensional arrangement distributes the electrical load across different spatial dimensions, reducing the burden on any single wiring path and improving luminous quality while preserving resolution.
2Measurement precision
If resolution of display apparatus is increased, then display quality is improved, but opening ratio is decreased
Solution Approach 1:
The pixel electrode is segmented into multiple parts extending in different directions. This segmentation allows for more efficient space utilization within the pixel region, increasing the opening ratio by reducing wasted space while maintaining the high resolution required for display quality.
Solution Approach 2:
The pixel electrode segments are configured with different orientations and extensions to dynamically adapt to the available space within the pixel region. This dynamic spatial arrangement maximizes the opening ratio while preserving resolution by optimizing the use of each directional segment.
