Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies restrict users from simultaneously watching 3D images in 2D or 3D formats or selecting different images based on personal preferences, as they require specific 3D glasses compatible with specific display methods, limiting compatibility and viewing experiences.
Innovation Solution
A method and system that allow users to select and watch 3D images in 2D or 3D formats using various types of 3D glasses by adjusting the display of left-eye and right-eye images through polarization, time synchronization, or color characteristics, enabling multiple users to watch different images on the same screen using composite division schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 3D image is played on a display device using polarization method, shutter method, or anaglyph method, then the 3D image can be viewed with 3D glasses, but all viewers must wear the same type of 3D glasses and cannot watch the image in 2D manner or without glasses
Solution Approach 1:
The patent segments the display screen into multiple independent display regions (first display region, second display region, etc.), where each region can independently display images with different characteristics (3D or 2D). This allows different users wearing different types of glasses (or no glasses) to view different regions simultaneously, resolving the contradiction between viewing format flexibility and display system complexity.
Solution Approach 2:
The patent introduces a spatial dimension by dividing the display screen into multiple regions, allowing simultaneous presentation of multiple image types (3D and 2D) in different spatial locations. This dimensional approach enables users with different viewing preferences to access their desired content without requiring the entire display system to support all viewing modes, thus improving adaptability while managing complexity.
2Adaptability or versatility
If the screen is divided into main screen and sub-screen to play images on different channels, then multiple images can be displayed simultaneously, but all viewers must watch the same format screen and cannot select only desired screens
Solution Approach 1:
The patent further segments each display region into multiple sub-regions (first sub-region, second sub-region, etc.), where each sub-region can independently display images from different channels or sources. This multi-level segmentation allows users to selectively view specific channels or image types in their preferred format (3D or 2D) by choosing the appropriate region, thereby improving image selection freedom while maintaining ease of operation through intuitive region-based selection.
3Quantity of substance
If various images are alternately arranged on a frame basis in a storage medium, then multiple images can be stored, but the implementation scheme for sound output means is not described making it impossible to check realizability
Solution Approach 1:
The patent segments the display system into multiple independent display regions, each capable of displaying different images simultaneously. This spatial segmentation approach allows multiple images to be stored and displayed without requiring complex temporal multiplexing or frame-based alternation, thereby improving image storage capacity while simplifying the implementation of associated sound output and other system components, making the overall system more complete and easier to manufacture.
