Solution Overview
Problem
Current three-dimensional image display devices using auto-stereoscopic methods, such as parallax barriers and lenticular lenses, face limitations in achieving high resolution and uniform image quality across different viewing angles, leading to suboptimal display performance.
Innovation Solution
A three-dimensional image display device incorporating a display panel with M×N pixels arranged in a matrix form, coupled with a viewpoint forming unit that includes L viewpoint forming devices arranged in a row direction, where each device separates and projects kn viewpoint images at different angles onto corresponding viewing zones, with the pitch of the lenticular lenses optimized to satisfy the condition O<P≤N·WhL, enhancing image resolution and display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a parallax barrier or lenticular lens is used for auto-stereoscopic display, then three-dimensional image display is achieved, but resolution and image quality uniformity deteriorate
Solution Approach 1:
The invention divides the display into multiple viewing zones, with each zone having dedicated viewpoint images and corresponding lenticular lenses. This segmentation allows precise control of light paths for different viewing angles, ensuring that each zone maintains high resolution and uniform image quality without the deterioration problems of conventional approaches.
Solution Approach 2:
The patent implements different optical characteristics for different regions of the display. Each viewing zone has optimized lenticular lenses with specific pitch values and viewpoint image arrangements tailored to that zone's requirements. This local optimization ensures that image quality and resolution are maintained uniformly across all viewing zones rather than degrading in certain areas.
2Reliability
If lenticular lenses with conventional pitch are used, then viewpoint separation is achieved, but resolution deteriorates due to non-uniform image distribution
Solution Approach 1:
The invention optimizes the pitch parameter of lenticular lenses for each viewing zone based on specific calculation formulas that consider the number of pixels, viewpoint images, and display dimensions. By precisely adjusting this critical parameter, the system achieves effective viewpoint separation while maintaining high resolution and preventing non-uniform image distribution across different viewing zones.
