3D Display Subtitle Multiplexing via Time-Division Optical Shutter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional picture viewing systems face challenges in efficiently displaying subtitles without causing visual fatigue, particularly when multiple languages are required, and current solutions complicate the configuration and increase costs.
Innovation Solution
A three-dimensional picture viewing system that multiplexes and displays multiple pictures with different parallaxes and subtitles in a time-division manner, using optical shutters to control the display of subtitles based on user-selected modes, allowing for easy switching between three-dimensional and two-dimensional views with or without subtitles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If subtitles are displayed in three-dimensional format, then subtitle information is provided to viewers, but visual fatigue increases due to difficulty in binocular fusion when head tilts
Solution Approach 1:
The patent extracts the subtitle display function from the three-dimensional picture display and implements it as a separate two-dimensional overlay. Subtitles are displayed in a two-dimensional plane superimposed on the three-dimensional picture rather than creating separate three-dimensional subtitle images for each eye. This extraction of the subtitle function from the 3D display system resolves the technical contradiction by providing subtitle information without requiring binocular fusion, thereby eliminating visual fatigue associated with 3D text viewing.
2Adaptability or versatility
If multiple subtitle languages are provided simultaneously, then diverse language needs are met, but system complexity increases
Solution Approach 1:
The patent implements time-division multiplexing for displaying multiple subtitle languages. Different language subtitles are displayed alternately in different time periods rather than simultaneously. The system switches between displaying subtitles in different languages by controlling the display timing, allowing viewers to select their preferred language while keeping the system configuration relatively simple. This periodic switching approach provides multi-language adaptability without requiring complex simultaneous display mechanisms.
3Loss of information
If three-dimensional pictures and subtitles are displayed together, then comprehensive information is provided, but the configuration becomes more complex
Solution Approach 1:
The patent merges the three-dimensional picture display and two-dimensional subtitle display into a single integrated display system. The subtitles are superimposed as a two-dimensional layer over the three-dimensional picture content, combining both information types in one display output. This merging approach provides comprehensive information (both 3D picture and 2D subtitles) while avoiding the need for separate independent display systems, thereby reducing overall configuration complexity.

AI summary
A three-dimensional picture viewing system includes: display system (2) that multiplexes and displays, in a time-division manner, three or more pictures including two or more pictures with different parallaxes and at least one subtitle picture and outputs a control signal indicating a switching timing of the pictures; input means (7) for designating an arbitrary display mode among a plurality of different display modes in which display pictures to be viewed are determined from among the three or more pictures; two shutters that switch a state between light transmission and light blocking; and a shutter driving circuit that specifies switching timings of the display pictures corresponding to the display mode designated by input means (7) based on the control signal, and independently controls opening/closing of the two shutters at the specified switching timing of the pictures.
