Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parallax barrier type 3D display devices are limited to either portrait or landscape mode, restricting the 3D display effect.
Innovation Solution
A 3D display device comprising a liquid crystal display panel and an electroluminescence display panel, where the electroluminescence panel forms alternating columns of bright and dark regions, and the liquid crystal panel has sub-pixels that display different grey scales for each bright region to create stereoscopic vision in both portrait and landscape modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a parallax barrier type 3D display device is used, then 3D display effect is achieved, but the device can only work in portrait mode or landscape mode, limiting the 3D display effect
Solution Approach 1:
The display device is segmented into two independent display panels: a first display panel for portrait mode 3D display and a second display panel for landscape mode 3D display. Each panel has its own parallax barrier structure optimized for its specific orientation, allowing the device to switch between modes without compromising 3D display quality. This segmentation resolves the contradiction by enabling multi-mode adaptability while maintaining simple, dedicated parallax barrier structures for each mode.
2Adaptability or versatility
If a switching type liquid crystal screen with parallax barrier is used, then 3D display in single mode is achieved, but the structure becomes complex and cannot support both portrait and landscape modes
Solution Approach 1:
The patent merges two separate display systems into one integrated device: a first display panel with portrait-mode parallax barrier and a second display panel with landscape-mode parallax barrier. Both panels are combined in a single device housing with shared control circuitry, achieving multi-mode capability while avoiding the complexity of a single switchable parallax barrier system. The merging principle allows the device to offer both portrait and landscape 3D display modes through independent, optimized panels.
3Adaptability or versatility
If parallax barrier is formed by rotating liquid crystal molecules, then 3D display function is achieved, but the structure requires switching type liquid crystal screen, polymer type liquid crystal layer, and polarizing film
Solution Approach 1:
The liquid crystal structure is segmented into two separate systems: a first polymer-type liquid crystal layer for the portrait mode panel and a second polymer-type liquid crystal layer for the landscape mode panel. Each layer is independently configured with its own electrode arrangement optimized for its specific display orientation. This segmentation eliminates the need for complex switchable structures, as each panel maintains a simple, dedicated liquid crystal configuration for its intended mode.
