3D Shutter Eyewear Synchronization via Display Response Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D shutter eyewear systems face challenges in synchronizing shutter opening and closing times with the display panel's response time, leading to potential crosstalk and suboptimal 3D viewing experiences due to variations in display technology and pixel illumination levels.
Innovation Solution
A system and method where 3D video viewing shutter devices communicate with 3D video display devices to determine transmittance intervals based on display panel response time, allowing for precise timing of shutter operations through wireless communication, such as Bluetooth links, to synchronize left and right shutter openings and closings with the display of 3D frames and blank frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3D shutter eyewear systems use fixed timing for shutter opening and closing, then the system is simple to implement, but crosstalk occurs due to mismatch with display panel response time
Solution Approach 1:
The shutter transmittance timing is made dynamic rather than fixed. The system adjusts the shutter opening and closing times based on the actual display panel response time, which varies with different display technologies and pixel illumination levels. This dynamic adaptation resolves the contradiction by allowing the system to maintain high synchronization accuracy while managing complexity through adaptive timing adjustments.
Solution Approach 2:
The system implements feedback by measuring or receiving information about the display panel response time and using this information to adjust the shutter timing. The eyewear system synchronizes with the display by accounting for the display's response characteristics, creating a closed-loop system that improves synchronization accuracy while managing complexity through intelligent timing adjustment.
2Object-affected harmful factors
If shutter timing is adjusted to match display response time, then crosstalk is reduced, but the system requires complex timing calculations and communication
Solution Approach 1:
The system uses feedback from the display device about its response time characteristics to adjust shutter timing. The display device communicates response time information to the eyewear system, which then calculates appropriate shutter transmittance intervals. This feedback mechanism reduces crosstalk by ensuring timing accuracy while managing complexity through automated calculations based on received display characteristics.
Solution Approach 2:
The system performs preliminary timing calculations based on expected or previously measured display response times. By pre-calculating appropriate shutter intervals and adjusting for known display characteristics before viewing, the system reduces crosstalk while minimizing real-time computational complexity during actual 3D viewing.
3Ease of operation
If wireless communication is used for synchronization, then ease of operation is improved, but potential synchronization delays may occur
Solution Approach 1:
The system exchanges synchronization information and response time data in advance before actual 3D viewing begins. By establishing timing parameters and communication protocols preliminarily, the system enables wireless operation convenience while minimizing delays during actual viewing through pre-configured timing information.

AI summary
A 3D video viewing shutter device receives display response time from a 3D video display device for determining shutter open and close times. Response time may correspond to display type, a particular display and/or a change in pixel illumination levels between frames. The shutter device receives response information during device initialization and/or corresponding to changing pixel illumination levels. A sequence of 3D frames may comprise a pattern of left frames, right frames, blank frames and/or frames comprising a combination of left and right frames. Based on display device and/or shutter device response times, the shutter device may extend shutter transmittance time during a frame display interval into a blank frame interval. Transmittance may be enabled during display of blank frames subsequent to left or right frames. The shutter device and display device may communicate via a wireless link for example, via a Bluetooth wireless link utilizing Bluetooth clocks.
