3D Display Flicker Elimination via Ambient Light Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
3D image display systems using shutter glasses often cause flickering due to frequency inconsistencies between ambient light and the display device or shutter glasses, particularly when ambient light frequencies match commercial power frequencies.
Innovation Solution
A method and system that detect ambient light frequency and adjust both the display device and shutter glasses' frequencies to synchronize with ambient light, ensuring that the display device operates at twice the ambient light frequency in 3D mode and matches ambient light frequency in 2D mode to prevent flickering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device operates at a fixed frequency (e.g., 60 Hz) and shutter glasses operate at a fixed frequency (e.g., 120 Hz), then the 3D image display function is achieved, but flickering occurs due to frequency inconsistency with ambient light (e.g., 50 Hz)
Solution Approach 1:
The patent makes the display device and shutter glasses frequencies dynamic rather than fixed. The controller automatically detects ambient light frequency and adjusts the display refresh rate and shutter frequency in real-time to maintain synchronization, eliminating flickering while preserving 3D display functionality
Solution Approach 2:
The patent changes the operating parameters (frequency) of the display device and shutter glasses based on detected ambient light conditions. By adjusting the refresh rate and shutter frequency to match ambient light frequency multiples, the system eliminates flickering while maintaining 3D display performance
2Object-affected harmful factors
If the display device frequency is updated to match ambient light frequency in 2D mode, then flickering is prevented, but the system complexity increases due to frequency detection and adjustment mechanisms
Solution Approach 1:
The patent implements a feedback mechanism where the controller continuously monitors ambient light frequency and automatically adjusts display and shutter frequencies accordingly. This closed-loop control prevents flickering while automating the complexity, requiring minimal user intervention
Solution Approach 2:
The system performs self-adjustment by automatically detecting ambient light frequency and configuring optimal display and shutter parameters without user input. The controller handles frequency synchronization autonomously, reducing the perceived complexity for users
3Object-affected harmful factors
If the shutter frequency is adjusted to twice the ambient light frequency in 3D mode, then flickering is eliminated, but the energy consumption increases due to higher frequency operation
Solution Approach 1:
The patent dynamically adjusts shutter frequency based on ambient light conditions and display mode. In 3D mode, the shutter operates at twice the ambient light frequency to eliminate flickering, while in 2D mode, it operates at the ambient light frequency, optimizing energy consumption for each operational context

AI summary
A method of displaying images includes detecting frequency of ambient light, updating frequency of a display device according to the frequency of the ambient light, and adjusting shutter frequencies of a pair of shutter glasses according to the frequency of the ambient light when the display device is in a 3D display mode. In this way, flickers caused by inconsistency between the frequency of the ambient light and the frequencies of the display device and the shutters of the shutter glasses can be avoided.
