Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passive 3D display systems face challenges in maintaining high resolution without increasing the number of sub-pixels, which can lead to monetary costs and space constraints, and existing solutions with active shutters or polarizing filters require complex electronics or result in resolution loss.
Innovation Solution
A passive 3D display system that arranges sub-pixels in a Bayer layout and applies a polarization filter with uniformly distributed green sub-pixels, ensuring each polarization type covers an equal number of green sub-pixels, thereby increasing perceived resolution without doubling the sub-pixel count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If passive polarizing filters are used in glasses, then cost is reduced and design is simplified, but resolution is lost because only 50% of LEDs can be seen by each eye
Solution Approach 1:
The display is divided into multiple sub-pixels with different polarization orientations (first and second polarization types) within the same physical pixel location. This segmentation allows both polarization types to be displayed simultaneously at full resolution, eliminating the need to lose 50% of pixels while maintaining passive 3D functionality.
Solution Approach 2:
Different regions of the display (sub-pixels) are assigned different polarization characteristics. By making the polarization property spatially varying at the sub-pixel level, the system enables each eye to receive high-resolution image data from the appropriate sub-pixels without requiring the viewer to wear polarizing glasses, thus maintaining resolution while using passive display technology.
2Measurement precision
If each pixel is doubled to provide one full pixel for each eye, then resolution is maintained, but monetary cost and surface area increase
Solution Approach 1:
Multiple sub-pixels with different polarization orientations are merged within a single physical pixel location. This merging allows the display to present different polarization types at the same spatial position, enabling both eyes to receive high-resolution information from the combined sub-pixels without physically doubling the pixel count, thus maintaining resolution while avoiding increased cost and surface area.
Solution Approach 2:
The system adds a polarization dimension to the traditional spatial pixel arrangement. Instead of only varying pixels in the x-y plane, the system introduces a third dimension (polarization orientation) at the sub-pixel level, allowing multiple image channels to be multiplexed in the polarization domain while maintaining the same physical pixel density and resolution.
3Measurement precision
If active shutters are used to switch between polarization types, then image resolution is maintained, but device complexity and cost increase due to large shutters in LED displays
Solution Approach 1:
The patent replaces the mechanical shutter system with a passive optical display approach using fixed polarization filters on sub-pixels. Instead of using moving shutters to switch between polarization types, the system uses stationary sub-pixels with different polarization characteristics that are always visible, eliminating the need for complex mechanical shutter components while maintaining image resolution.
Solution Approach 2:
The display structure itself provides the polarization separation function through the fixed arrangement of sub-pixels with different polarization orientations. The display is self-configured to present different polarization types simultaneously without requiring external active control mechanisms like shutters, making the system simpler and more cost-effective while preserving resolution.
