Solution Overview
Problem
Current three-dimensional image display devices using auto-stereoscopic methods, such as parallax barrier and lenticular lens schemes, face challenges in achieving high resolution and uniformity in displaying multiple viewpoints without deteriorating the resolution in the row and column directions.
Innovation Solution
A three-dimensional image display device incorporating a display panel with a viewpoint forming unit that projects different color images on specific viewing zones during sub-frames, utilizing a matrix arrangement of pixels and lenticular lenses or parallax barriers to increase the number of viewpoints while maintaining uniform resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a parallax barrier or lenticular lens scheme is used to display multiple viewpoints, then the number of viewpoints is increased, but the resolution in the row and column directions deteriorates
Solution Approach 1:
The display panel is divided into multiple dots, each dot containing multiple pixels arranged in a matrix. Each dot is responsible for displaying a specific viewpoint image, and the pixels within each dot are segmented to display different color images at different sub-frames. This segmentation allows multiple viewpoints to be displayed without sacrificing resolution, as each viewpoint has its own dedicated pixel group.
Solution Approach 2:
The patent introduces a time dimension by using sub-frames to display different color images. By sequentially displaying red, green, and blue color images at different sub-frames, the system achieves full color reproduction for multiple viewpoints without requiring additional spatial resources. This temporal multiplexing allows the same physical pixels to serve multiple viewpoints across different time intervals.
2Adaptability or versatility
If the number of viewpoints is increased to display detailed 3D images, then the display quality improves, but the resolution uniformity across different directions deteriorates
Solution Approach 1:
Each dot in the display panel is designed with a specific local structure where multiple pixels are arranged in a matrix and assigned to display specific color images for specific viewpoints. This local quality assignment ensures that each viewpoint region maintains uniform resolution characteristics, as the pixels within each dot are optimized for their specific viewpoint function rather than being uniformly distributed across the entire display.
Solution Approach 2:
The system uses periodic sub-frames to sequentially display different color images (red, green, blue) for each viewpoint. This periodic action allows the display to maintain resolution uniformity by systematically cycling through color images in a controlled sequence, ensuring that all color channels are represented evenly across all viewpoints without favoring any particular direction.

AI summary
A three-dimensional image display device including a dot displaying viewpoint images and a viewpoint forming unit. The dot displays first and second color images respectively having first and second colors of a first viewpoint image among the viewpoint images during a first sub-frame, and displays a third color image having a third color of the first viewpoint image during a second sub-frame. The viewpoint forming unit includes viewpoint forming devices, which are positioned at a first position during the first sub-frame to project the first and second color images on a viewing zone corresponding to the first viewpoint image, and positioned at a second position during the second sub-frame to project the third color image on the viewing zone.
