Transparent Tubular Display Module for 360-Degree Stereoscopic Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic image display devices have limited viewing areas due to their size, restricting the range in which a viewer can see a stereoscopic image without the need for glasses, and existing solutions do not effectively expand this range beyond the device's size limitations.
Innovation Solution
A display device with a transparent, tubular-shaped display module that emits light from opposite surfaces, featuring a first and second light emitting surface configured to display images in 360 degrees, along with a display region controller that adjusts the position of these surfaces based on viewer position tracking using a camera, allowing for a wider stereoscopic image-visible area.

Engineering Contradiction Analysis
1Area of stationary object
If a conventional stereoscopic image display device is used, then the device can display stereoscopic images, but the viewing area is limited due to the device size
Solution Approach 1:
The patent transitions from a conventional planar display to a transparent tubular display module that emits light from opposite surfaces. This three-dimensional structure allows viewers to see stereoscopic images from multiple angles and positions, effectively expanding the viewing area beyond the physical dimensions of the device by utilizing spatial depth and transparency.
Solution Approach 2:
The display module is divided into two separate light emitting surfaces facing opposite directions. Each surface can display images independently, allowing the system to serve multiple viewing zones simultaneously. This segmentation enables different viewers positioned at different locations to see appropriate images without interfering with each other, thus expanding the effective viewing area.
2Area of stationary object
If the display module size is increased to expand viewing area, then the viewing range widens, but the device becomes more complex and restrictive
Solution Approach 1:
The patent employs a tubular (circular or ellipsoidal) display module structure instead of a flat planar display. This curved, three-dimensional form factor naturally provides a wider field of view and accommodates multiple viewing angles without requiring a larger overall device footprint. The spherical/curved geometry inherently expands the viewing range while maintaining a compact form factor, avoiding the complexity of assembling multiple large planar panels.
