Reflective Liquid Crystal Display Panel for Multi-User Naked-Eye 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing naked-eye 3D display technology is limited to single-person viewing due to its design, which only allows for two fields of view, making it unsuitable for multi-person scenarios and prone to image crosstalk between adjacent visual fields.
Innovation Solution
A reflective liquid crystal display panel with multiple visual fields of view is implemented, utilizing reflective structures on a substrate to direct light to specific visual fields, and an anti-crosstalk structure is introduced to prevent image interference, allowing for multiple users to view distinct images without crosstalk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grating is disposed in front of or behind a display panel to achieve naked-eye 3D display, then two fields of view are obtained for left and right eyes, but the device is limited to single-person viewing and not suitable for multi-person scenarios
Solution Approach 1:
The display panel is divided into multiple independent visual field regions (first visual field, second visual field, etc.), each corresponding to a specific viewing angle range. Each visual field has its own pixel arrangement and optical path, allowing multiple users to view different images simultaneously without interference. This segmentation enables multi-person viewing while maintaining image quality.
Solution Approach 2:
Different regions of the display panel are configured with different local optical properties. Each visual field region has customized pixel parameters (such as pixel pitch, orientation, and optical characteristics) optimized for its specific viewing angle. This local quality approach allows each user to experience optimal display quality from their respective positions.
2Volume of moving object
If adjacent visual fields are arranged close together to reduce device size, then device compactness is improved, but image crosstalk occurs between adjacent visual fields
Solution Approach 1:
An anti-crosstalk structure is extracted and positioned between adjacent visual field regions. This structure selectively blocks light rays that would otherwise cross into adjacent visual fields, preventing image crosstalk. By removing this harmful light path while preserving the compact arrangement, both small device size and high image quality are achieved.
Solution Approach 2:
The anti-crosstalk structure serves as an intermediary element between adjacent visual fields. It mediates the optical interaction by selectively blocking crosstalk light while allowing the intended light paths to pass through. This intermediary structure enables close positioning of visual fields without compromising image quality.
3Adaptability or versatility
If multiple visual field regions are added to support multi-person viewing, then viewing capacity is improved, but manufacturing complexity and process difficulty increase
Solution Approach 1:
The anti-crosstalk structures for different visual fields are merged into a single integrated component or formed through a unified manufacturing process. This combining approach reduces the number of separate manufacturing steps and simplifies production, even as the number of visual fields increases. The merged structure maintains effectiveness across all visual field boundaries.
Solution Approach 2:
The display panel design incorporates universal structural elements and standardized components that can be replicated across multiple visual fields. By using universal design principles, the manufacturing process scales efficiently with the number of visual fields, reducing per-unit complexity and facilitating mass production.
