Shutter Glasses Ambient Brightness Control via Dynamic Shutter-Open Period
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shutter glasses do not effectively adjust ambient brightness, leading to insufficient perceived brightness, which can hinder the recognition of objects outside the display area during 3D image viewing, as they primarily focus on 3D image viewing without considering ambient brightness adjustments.
Innovation Solution
The implementation of shutter glasses with an adjusting circuit that generates an ambient brightness control signal to extend the shutter-open period longer than the activation time of a display device's backlight, allowing for dynamic adjustment of ambient brightness during two-dimensional image viewing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the shutter lens switches between open and closed states for 3D image viewing, then the 3D image display function is achieved, but the ambient brightness perceived by the user becomes insufficient
Solution Approach 1:
The shutter lens transitions from a fixed switching pattern to a dynamic adjustable pattern. The control unit modifies the shutter-open period based on ambient brightness conditions, allowing the system to adapt between 3D viewing mode (shorter open period) and ambient viewing mode (longer open period), thereby resolving the contradiction between maintaining 3D display function and ensuring sufficient ambient brightness for object recognition
Solution Approach 2:
The system changes the temporal parameter (shutter-open period duration) of the shutter lens operation. By extending the shutter-open period beyond the backlight activation time under low ambient brightness conditions, more ambient light reaches the user's eyes, improving object recognition while maintaining 3D viewing capability when needed
2Ease of operation
If the shutter-open period is extended to improve ambient brightness, then object recognition is enhanced, but the 3D image viewing quality may be compromised
Solution Approach 1:
The system dynamically adjusts the shutter-open period based on real-time ambient brightness detection. When ambient brightness is sufficient, the shutter returns to its original switching pattern for optimal 3D viewing. When ambient brightness is low, the shutter-open period is extended to improve object recognition, thus dynamically balancing the two competing requirements
Solution Approach 2:
The brightness detection unit provides feedback about ambient brightness levels to the control unit. This feedback loop enables the system to automatically adjust the shutter-open period according to actual lighting conditions, ensuring optimal performance for both 3D viewing and ambient object recognition without manual intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the perceived ambient brightness, enabling users to better recognize objects outside the display area and improving the overall image viewing experience by dynamically controlling the shutter-open period based on ambient conditions.
Implementation Method 1
When the liquid crystal layer in the shutter lens structure of the shutter glasses is in an open state, at least 50% of the ambient light is filtered by the polarizer
Implementation Method 2
the polarizer included in the shutter lens structure of the conventional shutter glasses will therefore cause the ambient brightness to have a significant decrease

AI summary
A method for adjusting an ambient brightness received by a pair of shutter glasses which are operative under a two-dimensional image viewing mode includes: generating an ambient brightness control signal; and adjusting a shutter-open period of eyeglass (s) of the shutter glasses according to the ambient brightness control signal, for adjusting a length of the shutter-open period of the eyeglass (s) to be longer than an activation time length of a backlight of a display device so as to adjust the received ambient brightness.
