3D Display Multiplexing for Simultaneous User Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D image display technologies are limited in their ability to allow multiple users to simultaneously experience diverse 3D image effects and to display both single and multiple 2D or 3D images effectively, restricting the usability of 3D viewing environments.
Innovation Solution
The method involves recognizing multiple pairs of 3D glasses connected to an image display apparatus, receiving and multiplexing video data at a predetermined frame rate, and frame-sequentially displaying the multiplexed data to allocate specific image frames to each user, allowing multiple users to view different images simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single image display apparatus displays multiple video data sets for multiple users, then the utilization ratio of the apparatus is maximized, but the complexity of controlling and managing multiple video streams increases
Solution Approach 1:
The display apparatus divides the display time into separate time slots for different video data sets. Each user's video data is segmented into specific time periods within a frame, allowing multiple users to view different content simultaneously without interfering with each other. This time-based segmentation enables efficient resource utilization while maintaining manageable control complexity.
Solution Approach 2:
The system implements periodic switching between different video data sets at predetermined frame rates. By allocating specific time periods for each video stream in a repeating cycle, the apparatus can efficiently manage multiple users' content while maintaining consistent display performance and controlled system complexity.
2Reliability
If the frame rate is increased to reduce ghost effects when displaying multiple video data sets, then image quality improves, but the processing load and energy consumption increase
Solution Approach 1:
The system dynamically adjusts the frame rate parameter based on the number of video data sets being displayed and the specific display conditions. By optimizing the frame rate rather than using a fixed high value, the system achieves sufficient image quality and ghost effect reduction while minimizing unnecessary processing load and energy consumption.
