Solution Overview
Problem
Existing display bodies with diffraction gratings only display latent images when viewed along a reflection direction, lacking aesthetic appeal and versatility.
Innovation Solution
A display body with a surface comprising multiple display regions, each having two reflection surfaces of different heights, forming unique images in different reflection directions, allowing interrelated images to be perceived as the observation direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a diffraction grating is used to record a latent image, then the image is clearly perceived when viewed along the reflection direction, but the aesthetic appearance is poor when viewed from other directions
Solution Approach 1:
The display surface is divided into multiple independent display regions, each containing multiple sub-regions with different reflection characteristics. This segmentation allows different areas to display different images or patterns depending on the viewing angle, thereby improving aesthetic appearance while maintaining image clarity in specific directions.
Solution Approach 2:
Different regions of the display surface are given different optical properties through varying the reflection surface structures. Each local region is optimized to reflect light in specific directions, creating a mosaic of images that are collectively aesthetically pleasing while maintaining clear latent image perception when viewed along the intended reflection direction.
2Adaptability or versatility
If multiple display region groups with different reflection directions are created, then interrelated images are displayed in different reflection directions, but the device complexity increases
Solution Approach 1:
Multiple display regions with different reflection characteristics are merged into a single integrated display surface. The reflection surfaces are combined in such a way that they collectively form interrelated images in different directions without requiring separate display components, thereby reducing overall device complexity while maintaining multi-directional display capability.
Solution Approach 2:
The display surface is designed to serve multiple functions simultaneously: it displays the latent image when viewed along the reflection direction and displays additional interrelated images in other reflection directions. This multi-functionality is achieved through a single unified structure rather than multiple separate systems, reducing complexity.
3Adaptability or versatility
If two reflection surfaces with different heights are used in each display region, then unique images are formed in different reflection directions, but the manufacturing precision requirements increase
Solution Approach 1:
The height parameter of the reflection surfaces is systematically varied across different display regions to create the desired optical effects. By controlling the height parameter in a structured manner rather than requiring precise control of every surface feature, the manufacturing complexity is reduced while still achieving the intended image variation with observation direction.

AI summary
A display body includes a display surface including a plurality of display region groups. Each display region includes at least one reflection surface that is configured to reflect light incident on the display surface toward an area including a corresponding one of reflection directions that are associated with the respective display region groups. Each display region group is configured to form an image unique to the display region group in a corresponding one of the reflection directions through reflection of light on the reflection surfaces in the display region group. The display region groups are configured to form, in two adjacent ones of the reflection directions, different images that have a interrelation between each other.
