Inclined Display Spatial Image Exhibition Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional display devices struggle to create an impactful and realistic three-dimensional effect when used in advertisements and exhibitions, as they require a straight line alignment with the viewer, microlens array, and image display surface, which limits the sense of realism and three-dimensional effect.
Innovation Solution
An exhibition device with an image-forming optical element in the upper surface of an enclosure and a display inclined at a predetermined angle, projecting a video picture as a spatial image in a virtual display area, with exhibition objects positioned to satisfy a specific distance relationship with the virtual display area's center, enhancing the three-dimensional effect and realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spatial image is projected directly in front of the microlens array with the viewer, microlens array and image display surface arranged in a straight line, then the image can be displayed, but the three-dimensional effect and sense of realism are insufficient
Solution Approach 1:
The patent transforms the conventional straight-line arrangement into a triangular spatial configuration by inclining the image display surface at an angle θ (30°≤θ<90°) relative to the element surface normal. This dimensional change creates a floating spatial image that extends beyond the microlens array plane, providing genuine three-dimensional effect and sense of realism while maintaining reliable image display capability.
2Ease of manufacture
If the image display surface is inclined at a predetermined angle with respect to the element surface, then the spatial image floats up and three-dimensional effect is enhanced, but the alignment complexity increases
Solution Approach 1:
The patent employs asymmetric inclination of the image display surface relative to the microlens array element surface, creating a deliberate angular relationship (θ) that generates the floating three-dimensional effect. This asymmetric configuration is complemented by asymmetric positioning of exhibition objects at specific distances and angles, achieving enhanced realism without requiring complex symmetric alignment mechanisms.
3Adaptability or versatility
If exhibition objects are placed near the spatial image, then the persuasiveness and appeal are increased, but the binocular parallax may cause discomfort if the distance is too short
Solution Approach 1:
The patent optimizes the distance parameter between exhibition objects and the spatial image to a specific range that balances two competing requirements: placing objects close enough to maximize persuasiveness and appeal, while maintaining sufficient distance to avoid excessive binocular parallax that would cause viewer discomfort. This parameter optimization enables effective exhibition while maintaining visual comfort.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively enhances the three-dimensional effect and realism of the displayed video picture, providing a stronger sense of floating and increased persuasiveness for advertisements and commercial use by ensuring the exhibition objects are positioned to maximize binocular parallax and spatial image interaction.
Implementation Method 1
an image-forming optical element provided in light-transmissive fashion in an upper surface of an enclosure for housing a display
Implementation Method 2
a planar image-forming optical element (micromirror array, see PTL 3) including a multiplicity of recessed unit optical elements or protruding unit optical elements arranged in an array and each having two mirror surfaces (corner reflectors) orthogonal to each other

AI summary
In an exhibition device and a video picture exhibition method according to the present invention, at least one exhibition object for reinforcing the three-dimensional effect of a spatial image is disposed in a region other than an upper surface of an image-forming optical element (micromirror array) in an upper surface of an enclosure (case) of the device and at a position where a distance from the center of a virtual display area of the spatial image projected from a display to over the enclosure thereto is not greater than a diagonal length of the virtual display area or at a position where the distance is not greater than a maximum diameter of the virtual display area. This achieves the effective display of an impressive two-dimensional video picture appearing three-dimensional in association with the exhibition object disposed on the upper surface.
