Cylindrical Lens Pixel Segmentation for Naked-Eye 3D Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked-eye stereoscopic image display modules face challenges in maintaining pixel resolution due to limited screen pixels being split and fused with binocular vision, resulting in reduced perception effects.
Innovation Solution
The display module incorporates a lens layer with cylindrical lenses that divide visual pixel groups into subgroups, ensuring partial or no overlap in a direction perpendicular to the lens centerline, allowing for independent light information reception by each eye without complete overlap, thus maintaining original resolution and enhancing perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels are split into different directions for naked-eye stereoscopic display, then 3D effect is achieved, but visual pixel resolution is reduced
Solution Approach 1:
The pixel array is segmented into multiple sub-pixel groups (first sub-pixel group, second sub-pixel group, third sub-pixel group, fourth sub-pixel group) with different arrangements. Each group corresponds to different viewing directions, allowing the display to provide 3D stereoscopic images for multiple viewpoints simultaneously while maintaining adequate resolution in each direction.
Solution Approach 2:
The invention transitions from conventional 2D pixel arrangements to a multi-dimensional pixel distribution strategy. Pixels are arranged in multiple groups along different directions (horizontal, vertical, and diagonal orientations), effectively utilizing spatial dimensions to achieve both 3D display capability and maintained resolution.
2Adaptability or versatility
If pixels are fused with binocular vision, then 3D perception is enhanced, but visual pixel resolution is reduced
Solution Approach 1:
Different regions of the display panel have different pixel arrangements optimized for specific viewing directions. The first sub-pixel group is optimized for one viewing direction while the second sub-pixel group is optimized for another direction, allowing each region to maintain high resolution for its intended purpose while collectively providing 3D perception.

AI summary
Display modules and display devices are provided. The display module includes a display panel and a lens layer disposed on a light-emitting side of the display panel. The display panel includes a plurality of visual pixel groups, and the lens layer includes a plurality of cylindrical lenses each covering one of the visual pixel groups. The cylindrical lens extends along a first direction and has a first virtual centerline parallel to the first direction and dividing the cylindrical lens into a first area and a second area. The visual pixel group includes at least one first subgroup corresponding to the first area and at least one second subgroup corresponding to the second area. In a top view direction of the display module, the first subgroup and the second subgroup are partially overlapped or not overlapped in a second direction perpendicular to the first direction.
