Wavy Electrode Display Panels for Diffraction Fringe Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with transparent display panels experience blurred images due to diffraction fringes caused by conductive traces, affecting the operation of photosensitive devices like cameras.
Innovation Solution
The display panel features wavy first electrodes with continuously changing widths and intervals, diffusing diffraction fringes in different directions to counteract their effects, thereby reducing diffraction and ensuring clear images for photosensitive devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a transparent display panel with conductive traces is used to achieve full-screen display, then screen-to-body ratio is improved, but diffraction fringes cause image blurring for photosensitive devices
Solution Approach 1:
The conductive traces are designed with wavy shapes instead of straight lines, creating curved surfaces that scatter and diffuse diffraction fringes in different directions. This curvature transforms the uniform diffraction pattern into a dispersed one, reducing the visibility of diffraction fringes while maintaining the transparent display function
Solution Approach 2:
The width of the wavy conductive traces varies continuously along their length, creating different local properties. This non-uniform width distribution causes diffraction fringes to appear at different positions and with different intensities at various locations, making them mutually counteract and reducing overall diffraction effects
2Object-affected harmful factors
If wavy first electrodes with continuously changing widths are used, then diffraction effects are reduced, but manufacturing complexity increases
Solution Approach 1:
The electrode design employs continuous parameter changes in width and spacing along the wavy traces, which can be precisely controlled through standard photolithography processes. This approach achieves diffraction reduction using conventional manufacturing parameters rather than requiring complex or specialized fabrication techniques
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively minimizes diffraction effects, allowing photosensitive devices under the display panel to capture high-definition images by diffusing diffraction fringes in different directions, thus improving image clarity.
Implementation Method 1

AI summary
A display panel, a display screen, and a display terminal are provided. The display panel includes a substrate and a plurality of wavy first electrodes disposed on the substrate. The plurality of first electrodes extend in parallel in the same direction and have an interval between adjacent first electrodes. In an extending direction of the first electrode, a width of the first electrode changes continuously or intermittently, and the interval changes continuously or intermittently.
