Liquid Crystal Grating with Sub-Electrode Layers for 3D Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal gratings require high attachment accuracy and provide a limited 3D display effect due to their constant visual range, resulting in a poor 3D display experience, especially when viewed from the edges of the display device.
Innovation Solution
A liquid crystal grating design featuring multiple sub-electrode layers with parallel sub-electrodes on each layer, allowing for adjustable light-shielding patterns and enhanced 3D display regions by dividing the electrode pattern into portions that can be energized to form light-shielding patterns, reducing the need for precise attachment and enabling dynamic adjustment of the 3D display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional liquid crystal grating is used with single electrode layer, then the structure is simple, but the attachment accuracy requirement is high and the 3D display region is limited
Solution Approach 1:
The first electrode is divided into multiple sub-electrode layers (first sub-electrode layer and second sub-electrode layer), with each layer containing multiple sub-electrodes. This segmentation allows the electrode pattern to be formed by combining projections of sub-electrodes from different layers, thereby reducing the requirement for attachment accuracy while achieving the desired light-shielding pattern.
2Adaptability or versatility
If conventional liquid crystal grating with fixed electrode pattern is used, then the device structure is simple, but the visual range and 3D display region are constant and limited
Solution Approach 1:
The electrode structure enables dynamic adjustment of the light-shielding pattern by selectively energizing different combinations of sub-electrodes from multiple sub-electrode layers. This allows the 3D display region and visual range to be adjusted according to different viewing conditions, transforming a static system into a dynamic one that can adapt to various user needs.

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 reduces the attachment accuracy requirements and enhances the 3D display region, providing a better 3D display effect regardless of the viewer's position, as the light-shielding patterns can be adjusted to optimize the 3D viewing experience.
Implementation Method 1
Liquid crystals in the liquid crystal layer are capable of being deflected under the effect of an electric field generated between the first electrode and the second electrode

AI summary
The present disclosure provides a liquid crystal grating, a display device and a display method. The liquid crystal grating includes a first electrode arranged on a first substrate and a second electrode arranged on a second substrate. The first electrode includes at least two sub-electrode layers. Each sub-electrode layer includes a plurality of sub-electrodes spaced apart from, and arranged parallel to, each other. A gap between every two adjacent sub-electrodes of one sub-electrode layer is capable of being covered by projections of the sub-electrodes of the other sub-electrode layer onto the one sub-electrode layer.
