Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional backplane processes are used for 3D display, then manufacturing simplicity is maintained, but continuous luminous display capability cannot be achieved
Solution Approach 1:
The pixel electrode is divided into multiple segments that extend across multiple pixel aperture areas. Each segment can be independently controlled while collectively forming a continuous luminous effect, enabling continuous display without requiring complex backplane processes.
Solution Approach 2:
The pixel electrode extends in the vertical direction across multiple pixel rows, transitioning from a traditional planar configuration to a three-dimensional structure. This dimensional change allows the electrode to span multiple aperture areas and create continuous luminous regions.
2Manufacturing precision
If pixel electrodes are confined to single pixel aperture areas, then manufacturing simplicity is maintained, but display continuity and definition are reduced
Solution Approach 1:
The pixel electrode is segmented into multiple portions, each located in different pixel aperture areas. These segments are controlled by separate control circuits, allowing independent optimization of each segment while maintaining overall display continuity and high definition.
Solution Approach 2:
The pixel electrode configuration is made dynamic through independent control of multiple segments. Each segment can be selectively activated or deactivated based on display requirements, enabling flexible control over display continuity and definition.
3Object-affected harmful factors
If data lines are oriented perpendicular to pixel electrodes, then manufacturing simplicity is maintained, but interference between sub-pixels increases
Solution Approach 1:
The data line orientation is changed from perpendicular to oblique relative to the pixel electrode arrangement. This asymmetric configuration reduces the overlap and interference between data lines and pixel electrodes, thereby minimizing sub-pixel interference while maintaining manufacturing simplicity.
