Lenticular Lens Film Slanted Axis Aperture Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lenticular lens type autostereoscopic 3D displays face luminance unevenness issues due to manufacturing process tolerances, which affect the observation of stereoscopic images as the viewing position changes, leading to brightness variations and hindering a natural stereoscopic experience.
Innovation Solution
The design incorporates a display panel with a lens film featuring lenticular lenses having a slanted axis and continuously arrayed along the lateral direction, with aperture areas divided into sub-aperture areas and expansion areas on either side, ensuring luminance uniformity by distributing the manufacturing process tolerance evenly across the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lenticular lens is attached on the display panel with conventional aperture area design, then the stereoscopic image can be displayed, but luminance unevenness occurs due to manufacturing process tolerances
Solution Approach 1:
The aperture area is divided into multiple sub-aperture areas (first sub-aperture area and second sub-aperture area) to distribute the impact of manufacturing tolerances. Each sub-aperture area is assigned to different view areas, ensuring that luminance variations are evenly distributed across all views rather than concentrated in one area.
Solution Approach 2:
Different sub-aperture areas are selectively assigned to different view areas based on their positional characteristics. The first sub-aperture area is assigned to a first view area while the second sub-aperture area is assigned to a second view area, creating local optimization that compensates for manufacturing variations in different regions.
2Reliability
If the aperture area is divided into sub-aperture areas assigned to different view areas, then luminance uniformity is improved, but the device complexity increases
Solution Approach 1:
The aperture area is segmented into sub-aperture areas that can be independently assigned to different view areas. This segmentation allows for flexible distribution of aperture areas across multiple views while maintaining a relatively simple overall structure that leverages the existing lenticular lens framework.

Function Achieved in This Case
This solution maintains uniform luminance across the display area, reducing luminance differences to less than 2% as the observer moves, providing a smooth and natural stereoscopic image without remarkable luminance variations, significantly improving video quality compared to existing technologies.
