Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If circuit wiring regions are densely distributed to connect driving electrode regions, then electrical connectivity is improved, but optical diffraction increases and transparency deteriorates
Solution Approach 1:
The patent divides the circuit wiring regions into multiple separate segments rather than using continuous dense wiring. The circuit wiring regions are arranged at intervals with optically transparent regions between them, segmenting the electrical connection path while reducing continuous optical obstruction. This segmentation allows light to pass through the gaps between wiring segments, reducing diffraction effects while maintaining electrical connectivity through the segmented circuit paths.
Solution Approach 2:
The patent transitions from a two-dimensional dense grid wiring layout to a more spaced-out arrangement that effectively utilizes the third dimension of light propagation. By creating intervals and spacing in the wiring layout, light can pass through the optically transparent regions between circuit wiring regions, adding a dimensional aspect to light transmission that reduces diffraction while maintaining electrical connections through the spaced wiring paths.
2Object-affected harmful factors
If circuit wiring regions are spaced apart to reduce diffraction, then transparency is improved, but electrical connectivity and signal transmission may be compromised
Solution Approach 1:
The patent combines multiple circuit wiring regions into integrated signaling systems where first signal lines and second signal lines work together to maintain electrical connectivity across spaced regions. The circuit wiring regions, though spaced apart, are connected through coordinated signal transmission paths that merge the functionality of distributed wiring segments, ensuring reliable electrical connectivity while maintaining the spaced-apart transparent layout.
Solution Approach 2:
The optically transparent regions serve as intermediaries between spaced circuit wiring regions, allowing light transmission while electrical signals are transmitted through the circuit wiring regions that connect driving electrode regions at intervals. The transparent regions mediate the optical path while the circuit wiring regions mediate the electrical connection, enabling both transparency and connectivity to coexist through the intermediary roles of these distinct regions.
3Illumination intensity
If optically transparent regions are increased in area to improve transparency, then light transmittance is improved, but the area available for circuit wiring and driving electrodes is reduced
Solution Approach 1:
The patent applies different functional qualities to different regions of the display panel. Circuit wiring regions are concentrated in specific localized areas with high electrical conductivity requirements, while optically transparent regions occupy the majority of the panel area for light transmission. This local differentiation allows the panel to have sufficient circuit wiring area in strategic locations while maintaining high overall light transmittance through the expansive transparent regions.
Solution Approach 2:
The patent segments the panel into distinct functional zones where circuit wiring regions and optically transparent regions are separated into discrete segments. This segmentation allows the circuit wiring to be concentrated in compact segments that provide necessary electrical connectivity, while the remaining segments are optimized for optical transparency. The segmented layout efficiently partitions the limited area between electrical functionality and optical performance.

Function Achieved in This Case
This approach effectively suppresses optical diffraction, enhances image quality, and maintains a certain degree of transparency in transparent display panels by optimizing the layout of circuit wiring and signal lines.
Implementation Method 1
An average light transmittance of the circuit wiring regions is less than ten percent, and an average light transmittance of the optically transparent regions is greater than that of the driving electrode regions and the circuit wiring regions
Implementation Method 2
Since the circuit wires may divide each penetrating region into a plurality of small penetrating areas, this may lead to the generation of diffraction, and the image quality may thus be lowered
