Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image display devices face challenges in maintaining image quality and brightness across wide viewing angles due to crosstalk issues, which are not adequately addressed by existing technologies.
Innovation Solution
The proposed solution involves a display device with a displaying part and a filtering part, including light-penetration-controlling regions (TC1 and TC2) positioned adjacent to signal generation regions (RS and LS) and polarization state-controlling regions (RG and LG), where TC1 and TC2 regions control light transmission to prevent crosstalk, allowing for wider viewing angles without brightness loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light-penetration-controlling regions (TC1 and TC2) are positioned adjacent to signal generation regions and polarization state-controlling regions, then crosstalk is prevented and viewing angle is widened, but device structure becomes more complex
Solution Approach 1:
The display device is segmented into distinct functional regions: signal generation regions (RS and LS for right and left eye), polarization state-controlling regions (RG and LG), and light-penetration-controlling regions (TC1 and TC2). This segmentation allows each region to perform its specific function independently, preventing crosstalk between left and right eye signals while maintaining wide viewing angles.
Solution Approach 2:
The light-penetration-controlling regions (TC1 and TC2) act as intermediary elements positioned between the signal generation regions and the polarization state-controlling regions. These intermediary regions control light transmission to prevent harmful crosstalk while allowing necessary light signals to pass through to the observer.
2Reliability
If light-penetration-controlling regions are added to control light transmission, then crosstalk is reduced, but manufacturing process becomes more difficult
Solution Approach 1:
The manufacturing process is segmented into distinct steps corresponding to the formation of different functional regions. The light-penetration-controlling regions are formed as separate entities from the signal generation and polarization control regions, allowing for specialized manufacturing techniques to be applied to each region independently, thereby facilitating overall manufacturing despite the increased complexity.
Solution Approach 2:
Different regions of the display device are given different local qualities and properties. The light-penetration-controlling regions have specific light transmission properties that differ from the signal generation regions and polarization state-controlling regions. This local differentiation allows each region to be optimized for its specific function while maintaining compatibility with the overall device architecture.
