360-Degree Holographic Display Using Mesh Screen Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D display systems, such as lenticular televisions, require viewers to remain in a specific location and are not effective in brightly lit environments or for holographic game displays that can be viewed from multiple sides, limiting their application and interaction.
Innovation Solution
A 3D display system that uses a screen element, such as a mesh or netting material, to reflect ambient light when not in use and transmit light from a 3D display to create a floating image, allowing for 360-degree viewing without the need for special glasses, and incorporates quarter sphere reflectors with 2D displays to enhance the 3D effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lenticular autostereoscopic displays are used, then 3D images can be displayed without special glasses, but viewers must remain in a specific location and at a predefined height to see the image correctly
Solution Approach 1:
The patent transitions from horizontal-only viewing (2D plane) to 360-degree spherical viewing (3D space) by arranging multiple lenticular displays vertically and using a hemispherical reflector to distribute images in all directions around the viewer
Solution Approach 2:
The patent divides a single large display into multiple smaller lenticular display units arranged in a vertical stack, with each unit contributing to different portions of the 360-degree viewing experience, allowing flexible positioning and modular configuration
2Illumination intensity
If conventional 3D displays are used in brightly lit environments, then the display can be visible, but the 3D image quality deteriorates and becomes difficult to see
Solution Approach 1:
The patent employs high-contrast alternating light and dark patterns in the interlaced image slices, with dark backgrounds that absorb ambient light and bright foreground elements that stand out, creating periodic visual cues that maintain image definition under varying lighting conditions
Solution Approach 2:
The patent utilizes high-contrast color schemes with dark backgrounds and brightly colored foreground elements, where the dark portions absorb ambient light and the bright portions emit or reflect light to maintain visibility across different environmental lighting conditions
3Adaptability or versatility
If standard monitors are added to walls for dynamic content, then entertainment value increases, but the displays become ubiquitous and fail to grab viewer attention
Solution Approach 1:
The patent uses high-contrast color patterns with dark backgrounds and bright, vibrant foreground elements that create visual pop and attract attention, combined with the novel 360-degree viewing experience that distinguishes it from conventional flat wall displays
Solution Approach 2:
The patent creates a three-dimensional immersive experience by arranging displays vertically and using hemispherical reflection to project images in 360 degrees around the viewer, transforming the flat wall display into a spatial environment that naturally captures attention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a 3D floating image to be viewed from any angle, even in brightly lit conditions, providing a dynamic and interactive experience without the constraints of traditional 3D displays, with a scalable design suitable for various environments and applications.
Implementation Method 1
The screen element is configured to reflect light from the viewing space so as to appear opaque to a viewer in the viewing space when the 3D display operates in the second state
Implementation Method 2
The screen element is configured to transmit at least a portion of the light output by the 3D display when the 3D display operates in the first state
Implementation Method 3
a 3D display operable to display a 3D image by outputting light into a viewing space

AI summary
A system for displaying three dimensional (3D) images. The system includes a 3D display operating in a first state to display a 3D image by outputting light into a viewing space and operating in a second state in which the 3D image is not displayed. The system further includes a screen element positioned between the 3D display and the viewing space. The screen element reflects light from the viewing space to appear opaque to a viewer in the viewing space when the 3D display operates in the second state. The screen element transmits the light output by the 3D display, whereby the 3D display image is perceivable by the viewer in the viewing space. The screen element includes a sheet of mesh or netting material that transmits light output by the 3D display through its pores or openings and may be a planar sheet of scrim or tulle.
