Engineering Contradiction Analysis
1Ease of manufacture
If circuit wiring is arranged in straight lines connecting driving electrode regions, then manufacturing is simple and wiring is efficient, but diffraction phenomenon occurs and image quality deteriorates
Solution Approach 1:
The patent applies asymmetry by arranging wiring regions at different angles relative to the arrangement direction. Specifically, odd-numbered wiring regions are arranged at a first angle while even-numbered wiring regions are arranged at a second angle, creating an asymmetric pattern that disrupts the periodicity causing diffraction. This asymmetric arrangement maintains manufacturing feasibility while effectively reducing diffraction phenomenon in transparent display panels.
Solution Approach 2:
The patent introduces angular deviations from the straight-line arrangement, effectively curving the wiring paths. By arranging wiring regions at inclined angles (first angle and second angle) rather than straight lines, the wiring follows a more curved trajectory that reduces the formation of regular diffraction patterns while maintaining electrical connectivity between driving electrode regions.
2Object-affected harmful factors
If wiring regions are arranged to reduce diffraction, then image quality improves, but manufacturing complexity increases
Solution Approach 1:
The patent segments the wiring arrangement into distinct odd-numbered and even-numbered wiring regions, each with specific angular arrangements. This segmentation allows the complex diffraction-reducing pattern to be systematically implemented through repetitive modular units, where each wiring region follows defined angular rules, thereby reducing overall manufacturing complexity while maintaining diffraction reduction effectiveness.
Solution Approach 2:
The patent employs periodic action by alternating between first angles and second angles for consecutive wiring regions. This periodic pattern of angular variation creates a systematic approach to diffraction reduction that can be easily manufactured through repetitive processes, reducing the complexity of implementing the overall asymmetric pattern across the entire display panel.
3Ease of operation
If transmission regions are divided into small regions by circuit wiring, then driving electrodes can be properly positioned, but diffraction phenomenon increases and image quality decreases
Solution Approach 1:
The patent applies asymmetry to the wiring arrangement around transmission regions, using alternating first and second angles for odd and even wiring regions. This asymmetric pattern allows driving electrodes to be properly positioned within transmission regions while disrupting the periodicity that causes diffraction, thereby maintaining both ease of electrode positioning and reducing diffraction phenomenon.
