Curved Conductive Trace Layout for Transparent Display Diffraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The diffraction phenomenon occurring when light passes through gaps between adjacent conductive traces in a transparent display region of a display panel results in poor image quality for photosensitive elements like cameras.
Innovation Solution
The conductive traces between film layers in the transparent display region are arranged in a preset function curve shape, disrupting the regular distribution of gaps and destroying structural periodicity, thereby improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conductive traces are arranged in straight lines with regular spacing, then manufacturing is simple and easy, but diffraction phenomenon occurs when light passes through gaps, degrading image quality
Solution Approach 1:
The patent applies asymmetry by arranging conductive traces in curved patterns rather than straight lines, creating irregular gap distributions that destroy the structural periodicity responsible for diffraction. The curved traces with varying radii and spacing create asymmetric gap patterns that prevent coherent diffraction while maintaining electrical connectivity.
Solution Approach 2:
The patent employs curvature by designing conductive traces as arcs or curves instead of straight lines. This curvature creates non-uniform gap distributions between adjacent traces, disrupting the regular periodic structure that causes diffraction phenomena, thereby improving image quality for under-screen cameras.
2Object-affected harmful factors
If conductive traces are arranged in curved patterns to reduce diffraction, then image quality improves, but manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the geometric parameters of conductive traces (curvature radius, spacing, orientation) to optimize the balance between diffraction reduction and manufacturing feasibility. By carefully controlling these parameters, the design achieves irregular gap patterns that minimize diffraction while remaining compatible with standard fabrication processes.
