Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D electronic display devices require complex driving methods for multiple 3D viewpoints, increasing fabrication costs and complexity, especially when trying to accommodate multiple viewers and provide motion parallax without the need for head tracking devices.
Innovation Solution
A 3D display device featuring a display panel with sub-pixels arranged in sub-pixel repeating groups and a cylindrical lens grating that divides sub-pixels into 3D viewpoints, allowing for a simpler driving method similar to 2D displays by using a cylindrical lens grating with predetermined parameters to refract light into parallel beams, forming multiple 3D viewpoints with the same sub-pixel arrangement as the sub-pixel groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grating is disposed on top of the display panel to split pixels into multiple 3D viewpoints, then 3D display capability is improved, but the driving method becomes complicated and fabrication cost increases
Solution Approach 1:
The display panel is divided into multiple sub-pixel repeating groups with different color arrangements, where each group corresponds to a specific 3D viewpoint. This segmentation allows different regions to independently form complete color pixels when viewed from different angles, enabling multiple viewpoints without complex driving methods
Solution Approach 2:
Different sub-pixel repeating groups are assigned different color compositions (e.g., RGB, BGR, GB, RB) tailored to their specific viewpoint requirements. This local quality differentiation ensures that each viewpoint receives the correct color information while maintaining overall 3D display functionality
2Adaptability or versatility
If multiple 3D viewpoints are implemented to accommodate multiple viewers, then viewer capacity is improved, but device complexity and fabrication cost increase
Solution Approach 1:
The display panel uses a universal driving method that can drive all sub-pixels simultaneously, making the same driving circuitry serve multiple 3D viewpoints. This multi-functionality allows the system to accommodate multiple viewers without requiring separate driving circuits for each viewpoint, thereby reducing fabrication cost
Solution Approach 2:
Multiple sub-pixels with different colors are merged within each sub-pixel repeating group to form complete color pixels for each viewpoint. This merging allows a single display panel structure to serve multiple viewpoints simultaneously, reducing the need for additional components and lowering fabrication costs
3Reliability
If sub-pixels are divided into multiple 3D viewpoints using a cylindrical lens grating, then 3D display performance is improved, but the sub-pixel arrangement complexity increases
Solution Approach 1:
The sub-pixels are pre-arranged in repeating groups with specific color patterns during manufacturing, before the device is used. This preliminary arrangement ensures that when light passes through the cylindrical lens grating, each viewpoint automatically receives the correct color information without requiring complex real-time control
Solution Approach 2:
The sub-pixel repeating groups use copied color patterns (e.g., RGB, BGR, GB, RB) that are systematically repeated across the display panel. This copying approach simplifies the overall arrangement complexity by using a limited set of patterns that can be consistently replicated, while still providing accurate color information to multiple viewpoints
