Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic image display devices face challenges in adapting to various display modes, particularly when switching between portrait and landscape orientations, as traditional barriers are not compatible with landscape modes, limiting the availability of stereoscopic images in these configurations.
Innovation Solution
An active barrier system utilizing liquid crystal cells arranged in a matrix format, driven by a controller and barrier driver, which selectively changes transparency and opacity to adapt display patterns for different modes, enabling stereoscopic image display in both portrait and landscape orientations by adjusting the arrangement of opaque and transparent regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional barrier with fixed opaque and transparent regions is used, then the barrier can display stereoscopic images in portrait mode, but it cannot adapt to landscape mode display
Solution Approach 1:
The barrier device employs liquid crystal cells that can dynamically change their optical state between transparent and opaque based on control signals. This dynamic capability allows the same barrier structure to adapt to both portrait and landscape display modes by reconfiguring the transparency pattern of the liquid crystal cells, eliminating the need for multiple fixed barriers for different orientations.
Solution Approach 2:
The invention changes the optical parameters (transparency/opacity) of the barrier regions through electrical control of liquid crystal cells. By controlling the liquid crystal cells to be either transparent or opaque, the barrier can reconfigure its display pattern to match different screen orientations, enabling adaptability without structural modification.
2Adaptability or versatility
If a barrier is designed for portrait mode only, then the barrier structure is simple, but stereoscopic images are not available in landscape mode
Solution Approach 1:
The liquid crystal-based barrier can dynamically reconfigure its transparent and opaque region patterns to match the current display orientation. When the display switches between portrait and landscape modes, the controller adjusts the liquid crystal cell states accordingly, maintaining stereoscopic functionality without requiring the user to change their viewing position.
3Adaptability or versatility
If wider opaque regions are used in the barrier, then multi-view stereoscopic images can be displayed, but the transparent regions become narrower reducing viewing comfort
Solution Approach 1:
The barrier uses liquid crystal cells that can be precisely controlled to create optimized transparent and opaque patterns for multi-view display. This dynamic control allows the system to maintain adequate transparent region widths for viewing comfort while still achieving multi-view capability, as the patterns can be adjusted based on the specific display requirements rather than being fixed.
