Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the size of pixel structure is restricted to allocate sufficient transparent area, then transparency is improved, but pixel density deteriorates
Solution Approach 1:
The display panel is divided into multiple sub-pixel structures (first, second, third color pixel structures) arranged in a radial pattern around a geometric center. Each sub-pixel can be independently controlled, allowing the transparent area to be segmented and optimized while maintaining high pixel density through efficient spatial utilization.
Solution Approach 2:
The pixel structures are arranged in a radial configuration around a geometric center rather than a conventional linear or grid pattern. This dimensional reorganization allows for more efficient use of the display area, enabling both high transparency and high pixel density by utilizing angular and radial spatial relationships.
2Quantity of substance
If the pixel structure size is increased to improve pixel density, then pixel density is improved, but transparent area is reduced
Solution Approach 1:
Different regions of the display panel are assigned different functions: the central geometric center area serves as a transparent region, while the radial arms contain the pixel structures. This local differentiation allows pixel structures to be concentrated in specific areas to achieve high pixel density while preserving large transparent areas in the center and between radial structures.
Solution Approach 2:
The radial arrangement distributes pixel structures along angular dimensions rather than consuming linear horizontal or vertical space. This allows pixel density to be increased by utilizing the angular dimension, while the central and inter-radial areas remain transparent, effectively decoupling pixel density from transparent area reduction.
3Device complexity
If conventional pixel arrangement is used to simplify structure, then device complexity is reduced, but pixel density and transparency optimization is limited
Solution Approach 1:
The pixel structures are arranged asymmetrically in a radial pattern around a geometric center rather than a symmetric grid. This asymmetric arrangement optimizes the distribution of transparent and colored areas, allowing for higher pixel density while maintaining large transparent regions, and enables more efficient routing of scanning and data lines.
Solution Approach 2:
The radial pixel structure design serves multiple functions simultaneously: it achieves high pixel density through compact radial arrangement, maintains large transparent areas in the center and between arms, provides efficient pathways for scanning and data lines along the radial structure, and enables flexible control of different color sub-pixels. This multi-functionality reduces overall device complexity by integrating multiple objectives into a single design.
Data Source
AI summary
A transparent display panel including a transparent substrate and a plurality of display units formed on the substrate is provided. Each of the display units includes a color light area and a least one of transparent areas disposed around the color light area. The color light area has a geometric center, a first color pixel structure, a second color pixel structure, and a third color pixel structure. The first, second and third color pixel structures take the geometric center as a center in each display unit and are disposed in a radial way corresponding to the center to form the color light area.
