Display Panel Electrode Layout for Moire-Reduced Glasses-Free 3D
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glasses-free 3D display technologies face challenges such as low visual resolution, discontinuous 3D views, and the occurrence of moire patterns due to large electrode spacings.
Innovation Solution
The display panel is designed with a plurality of first-color subpixels, each comprising a base with driving electrodes, patterned first and second electrodes, and an intermediate passivation layer. The electrodes are arranged in an array with adjacent electrode front projections either adjacent or partially overlapping, reducing the gap between electrodes and minimizing moire patterns.

Engineering Contradiction Analysis
1Measurement precision
If traditional subpixel structures are used in glasses-free 3D display, then the display can show 3D images without glasses, but the resolution is low and the viewing angle is limited
Solution Approach 1:
Each subpixel is divided into multiple independent electrode regions (first electrode and second electrode) that can be controlled separately. This segmentation allows different parts of the same subpixel to direct light to different eyes, enabling high-resolution 3D display with expanded viewing angles by independently controlling light paths for multiple viewers.
Solution Approach 2:
The patent introduces a vertical dimension to electrode arrangement by stacking first and second electrodes at different heights within the same subpixel footprint. This multi-layer electrode structure enables three-dimensional light control, allowing light from a single subpixel to reach multiple eyes at different viewing angles simultaneously.
2Manufacturing precision
If electrode spacing is reduced to minimize moire patterns, then image quality improves, but manufacturing precision requirements increase
Solution Approach 1:
By arranging electrodes in multiple vertical layers rather than a single plane, the patent reduces the horizontal spacing between electrodes without increasing manufacturing difficulty. The staggered multi-layer arrangement minimizes moire patterns while maintaining feasible fabrication tolerances through the additional vertical dimension.
3Measurement precision
If multiple electrodes are added to each subpixel to improve 3D display quality, then resolution and viewing angle increase, but device complexity increases
Solution Approach 1:
The patent combines multiple electrode functions within a single subpixel structure. The first and second electrodes share the same subpixel footprint and are integrated into the same pixel circuit, allowing high-resolution 3D display without proportionally increasing the overall number of pixels or circuit complexity.
Solution Approach 2:
Each subpixel with multiple electrodes serves multiple functions simultaneously: it displays color information, controls 3D depth information, and directs light to different eyes. This multi-functionality achieves high-resolution 3D display without requiring separate dedicated structures for each function.
