Parallax Barrier Projection for 3D Space Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for projecting space images often require specialized viewing equipment or restrict the viewing angle, and existing technologies cannot project images that can be viewed from every direction while maintaining a three-dimensional effect.
Innovation Solution
An apparatus comprising a receiving unit, a display unit, a control unit, and a projection unit that includes various optical components such as lenses and mirrors, allowing the space image to be projected from any direction by adjusting the position and state of these units based on received signals, enabling flexible projection and depth changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polarization or shutter glass methods are used to project space images, then three-dimensional effect is achieved, but users must wear specially-designed glasses which restricts viewing flexibility
Solution Approach 1:
The patent extracts the essential function of 3D display (depth perception) from the specialized glasses requirement by using a parallax barrier that directs light to different eyes based on horizontal position, eliminating the need for users to wear special glasses while maintaining the three-dimensional effect
Solution Approach 2:
The patent creates a universal viewing solution where any user can view the 3D space image without specialized equipment by using a parallax barrier that works with standard eyes, making the display accessible to everyone regardless of whether they wear glasses or not
2Ease of operation
If parallax barrier method is used to project space images, then viewing angle is expanded, but image cannot be touched due to lack of screen
Solution Approach 1:
The patent merges the parallax barrier method with a transparent screen by combining the light-blocking barrier structure with a transparent substrate that allows light transmission, creating a hybrid display that provides both wide viewing angle and physical screen presence for touch interaction
Solution Approach 2:
The patent uses a composite structure consisting of a transparent screen material combined with a parallax barrier layer, where the transparent screen provides touch capability and the parallax barrier provides 3D viewing angle expansion, achieving both functions simultaneously
3Ease of operation
If volume method with spinning screen is used, then image can be viewed from every direction, but three-dimensional effect is reduced and image cannot be touched
Solution Approach 1:
The patent uses a dynamic parallax barrier that can adjust its pattern or position to control which areas of the transparent screen display 3D images to different viewers, enabling multiple viewing directions while maintaining strong three-dimensional effect through controlled light blocking and transmission patterns
