Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display systems cause visual fatigue due to the conflict between convergence and eyeball adjustment processes, leading to dizziness and nausea when viewers watch 3D images for extended periods.
Innovation Solution
3D shutter glasses with a light transmitting hole array in each lens, controlled by liquid crystal layers to alternately open and close according to a predetermined timing, ensuring that only one light transmitting hole is open at a time to receive either left or right eye data images, synchronizing with the 3D display system's image alternation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3D display systems are used with full lens glasses, then the 3D effect can be achieved, but visual fatigue occurs due to conflict between convergence and adjustment distances
Solution Approach 1:
The patent divides the continuous lens into discrete light transmitting holes arranged in arrays. Each eye receives light through multiple separated holes rather than a continuous lens, enabling selective transmission of left-eye and right-eye images at different spatial locations. This segmentation allows the system to control which eye sees which image at any given moment, resolving the convergence-adjustment conflict by preventing simultaneous viewing of disparate depth planes.
Solution Approach 2:
The patent implements periodic switching between left-eye and right-eye image transmission through alternating activation of light transmitting hole arrays. The display device and glasses synchronize to alternately transmit left-eye images through left-eye holes and right-eye images through right-eye holes at predetermined time intervals. This periodic action ensures that each eye receives its designated image sequence without cross-contamination, eliminating the visual fatigue caused by simultaneous convergence and adjustment conflicts.
2Object-affected harmful factors
If the range of depth of focus is controlled in 3D image production, then visual fatigue is partially relieved, but the improvement is not significant and fatigue varies by individual
Solution Approach 1:
The patent introduces light transmitting holes as intermediary elements between the display screen and the eyes. These holes act as spatial filters that selectively transmit light from specific regions of the display to specific eyes. By positioning holes at precise locations and controlling their transmission timing, the system mediates the interaction between the viewer's eyes and the 3D display, ensuring that each eye receives only the intended image sequence. This intermediary mechanism provides a more effective and consistent solution to visual fatigue compared to simply controlling depth of focus range.
3Ease of operation
If light transmitting hole arrays are used in 3D shutter glasses, then convergence and adjustment distances are synchronized, but the device complexity increases
Solution Approach 1:
The patent utilizes differences in light transmission properties (analogous to color changes in principle) by selectively transmitting left-eye and right-eye images through different spatial locations and time periods. The light transmitting holes are positioned and activated to create distinct transmission paths for each eye, effectively using spatial and temporal differentiation rather than color filtering. This approach achieves proper eye coordination while avoiding the complexity of color-based solutions.
Solution Approach 2:
The patent implements dynamic control of the light transmitting hole arrays through synchronized switching mechanisms. The holes are not statically open or closed but are dynamically activated and deactivated in coordination with the display device's image transmission sequence. This dynamic behavior allows the glasses to adapt in real-time to the displayed content, ensuring that each eye receives the correct image at the correct time, thereby achieving ease of operation despite the increased structural complexity.
