Solution Overview
Problem
Conventional auto-stereoscopic display technologies require a fixed viewer distance and strict alignment precision, limiting convenience and increasing fabrication difficulties.
Innovation Solution
The method involves a stereo display apparatus with a periodic structure and pixel plane that divides space into N view zones, allowing adjustment of display content based on viewer distance, using sub-pixel units and reference points to blend image information and adjust projection areas, thereby increasing error tolerance and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional auto-stereoscopic display technology is used with fixed viewer distance and strict alignment precision, then display quality is maintained, but convenience is limited and fabrication difficulty increases
Solution Approach 1:
The patent segments the display into multiple view zones (N view zones) with corresponding projection areas on the pixel plane. Each view zone is associated with specific sub-pixel units, allowing the system to serve multiple viewing positions simultaneously. This segmentation enables flexible viewer distance adjustment while maintaining display quality, resolving the contradiction between convenience and alignment precision requirements
Solution Approach 2:
The patent changes the parameter of view zone configuration by dividing space into N view zones and adjusting the projection areas corresponding to each zone. By modifying the image information for each view zone based on its corresponding sub-pixel units, the system adapts to different viewer distances without requiring strict alignment, thus improving convenience while reducing manufacturing precision demands
2Reliability
If strict alignment precision between optical device and display apparatus is required, then display quality is maintained, but fabrication difficulty and cost increase
Solution Approach 1:
The display apparatus is segmented into multiple independent view zones with dedicated projection areas and sub-pixel units. This segmentation allows each zone to be optimized independently, reducing the need for strict overall alignment between the optical device and display apparatus. The modular approach simplifies fabrication while maintaining display quality through localized optimization
Solution Approach 2:
The patent implements dynamic adjustment of image information for each view zone based on the corresponding sub-pixel units and projection areas. This dynamic approach allows the system to adapt to variations in alignment during fabrication, maintaining display quality without requiring extremely precise manufacturing. The flexible configuration compensates for manufacturing tolerances
3Adaptability or versatility
If fixed viewer distance is required, then alignment precision requirements are reduced, but viewer convenience and view freedom are limited
Solution Approach 1:
The patent creates a multi-functional display system that serves multiple viewing distances and positions simultaneously through N view zones. Each view zone can accommodate different viewer distances, making the display universally applicable to various viewing scenarios. This multi-functionality enhances both view freedom and convenience, allowing viewers to freely adjust their position while maintaining image quality

AI summary
An image display method of a stereo display apparatus is provided. The image display method includes the following steps. A stereo display apparatus is provided, wherein the stereo display apparatus provides N view zones for a viewer and includes a periodic structure and a pixel plane. N view zones are divided in a space according to the N value. Projection areas corresponding to each of the view zones are formed on the pixel plane by the periodic structure, wherein each of the projection areas corresponds to at least one sub-pixel unit on the pixel plane. Image information of each view zone is obtained according to the corresponding sub-pixel units. A stereo image is displayed by blending image information of each view zone.
