Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional image display devices are unable to project three-dimensional images or objects moving in three-dimensional space, as they only project flat images onto flat screens and cannot combine or match images to form a three-dimensional representation.
Innovation Solution
An image display device comprising a display device, an optical modulation element, and a modulation device, where the optical modulation element is angled between 20 degrees and 70 degrees relative to the display surface, allowing images to be projected at different imaging positions with varying distances from the optical modulation element, enabling the creation of floating three-dimensional images or simulating movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional flat display devices project images onto a flat screen, then the image can be displayed clearly, but the three-dimensional image and movement in three-dimensional space cannot be shown
Solution Approach 1:
The patent applies dimensionality change by tilting the optical modulation element at an angle of 20-70 degrees relative to the display surface, transforming the traditional two-dimensional flat image projection into a three-dimensional floating image display. This angular orientation enables light to modulate and form images at different depths, creating a three-dimensional visual effect while maintaining a relatively simple display structure.
Solution Approach 2:
The optical modulation element serves as an intermediary component between the flat display surface and the projected image. By positioning this element at a specific angle, it mediates the transformation from two-dimensional display data to three-dimensional floating images, enabling depth perception and spatial movement without requiring complete structural redesign of the display system.
2Adaptability or versatility
If two flat display devices project images at different distances, then depth perception may be improved, but the images remain separated and cannot be combined to form a three-dimensional image
Solution Approach 1:
The patent merges the functions of multiple display devices into a single integrated system. By using one display device with a tilted optical modulation element, images at different distances are combined and modulated together to form a unified three-dimensional image, eliminating the need for separate display devices while achieving depth perception and spatial integration.
Solution Approach 2:
The optical modulation element performs multiple functions: it modulates light from the display, creates floating images at different depths, and integrates multiple image layers into a single three-dimensional composition. This multi-functionality replaces what would traditionally require multiple separate display devices, reducing system complexity while maintaining versatility.
3Adaptability or versatility
If the optical modulation element is angled at 20-70 degrees relative to the display surface, then floating three-dimensional images can be projected, but the alignment and positioning precision become more challenging
Solution Approach 1:
The patent specifies a parameter range (20-70 degrees) for the optical modulation element angle rather than a single fixed value. This parameter flexibility allows manufacturers to achieve three-dimensional image projection within a acceptable tolerance range, reducing the stringency of alignment precision requirements while maintaining the core functionality of floating image display.

AI summary
Disclosed is an image display device including a display device, an optical modulation element, and a modulation device. When the modulation device is in a first state, the display device projects a first image at a first imaging position through the optical modulation element. When the modulation device is in a second state, the display device projects a second image at a second imaging position through the optical modulation element. A minimum distance from the first imaging position to the optical modulation element is different from a minimum distance from the second imaging position to the optical modulation element.
