Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic 3D display technologies face challenges such as increased costs and Moiré patterns due to separate manufacturing of 3D optical cells, and existing stereopsis image display apparatuses require separate components for 2D and 3D viewing modes.
Innovation Solution
A stereopsis image display apparatus with a single display panel incorporating 2D and 3D subpixels and lenses that allow for switching between 2D and 3D modes, eliminating the need for separate 3D optical cells and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate 3D optical cell is used to implement 3D display, then 3D image display capability is achieved, but manufacturing cost increases and Moire pattern occurs
Solution Approach 1:
The patent merges the 3D optical cell functionality directly into the display panel by integrating lenses with each subpixel during the display panel manufacturing process. This eliminates the need for a separate 3D optical cell component, reducing manufacturing steps and cost while maintaining 3D display capability.
Solution Approach 2:
The display panel is designed to perform both 2D and 3D display functions using the same panel structure. The integrated lenses enable the panel to switch between 2D mode (when lenses are transparent) and 3D mode (when lenses refract light), providing multi-functionality without requiring separate display devices.
2Adaptability or versatility
If a separate 3D optical cell is added to the display panel, then 3D display function is enabled, but device thickness and weight increase
Solution Approach 1:
By combining the 3D optical cell with the display panel during manufacturing, the patent eliminates the need for a separate optical cell component that would add weight. The integrated structure uses the same materials and fabrication processes, resulting in no additional weight penalty.
3Adaptability or versatility
If 3D optical cell is manufactured separately from display panel, then 3D display capability is achieved, but manufacturing process complexity increases
Solution Approach 1:
The patent integrates the 3D optical cell manufacturing into the display panel fabrication process, combining multiple manufacturing steps into a single integrated process. This eliminates the complexity of coordinating separate manufacturing processes and assembly operations.
4Adaptability or versatility
If separate 3D optical cell is used, then 3D image display is achieved, but Moire pattern occurs due to alignment structure
Solution Approach 1:
By integrating the lenses directly with the subpixels during display panel manufacturing, the patent eliminates the alignment structure between separate components. The lenses are formed as part of the subpixel structure itself, removing the source of Moire patterns that arise from misalignment between stacked components.
