Naked Eye Stereoscopic Display Viewer Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional naked eye type stereoscopic display devices often cause discomfort and dizziness in viewers due to improper alignment of left and right eye images, as they do not effectively determine whether the viewer's position is within the stereoscopic image regions.
Innovation Solution
A two-dimensional and naked eye type stereoscopic switchable display device that includes a detection system to determine the viewer's position and an indicator system to emit different colored lights, allowing the viewer to adjust their position for optimal viewing, comprising a display module with a parallax barrier or lenticular lens and a control device to manage image display based on detected position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional naked eye type stereoscopic display device is used, then the viewer can see stereoscopic images without wearing glasses, but the viewer may feel uncomfortable or dizzy due to improper alignment of left and right eye images
Solution Approach 1:
The patent employs a detection device to detect the viewer's position and feeds this information back to the control device, which then adjusts the display mode (2D or stereoscopic) accordingly. This feedback mechanism ensures that stereoscopic images are only displayed when the viewer is positioned correctly, preventing discomfort and dizziness while maintaining ease of viewing.
Solution Approach 2:
The display device dynamically switches between 2D display mode and stereoscopic display mode based on real-time detection of the viewer's position. This dynamic adaptation allows the system to optimize the viewing experience by selecting the appropriate display mode, thereby eliminating discomfort and dizziness associated with improper image alignment.
2Reliability
If multiple left eye image regions and right eye image regions are alternately arranged in three-dimensional space, then the stereoscopic effect is achieved, but the viewer cannot see the stereoscopic image at all perspectives and positions
Solution Approach 1:
The system dynamically adjusts the display mode based on the viewer's position. When the viewer is not in the appropriate stereoscopic viewing region, the system switches to 2D display mode, ensuring that the viewer can always see the image clearly regardless of their position, thus maintaining both stereoscopic effect reliability and viewing adaptability.
Solution Approach 2:
The patent changes the display parameters (switching between 2D and stereoscopic modes) based on the detected viewer position. This parameter adjustment ensures that the system adapts to different viewing conditions, allowing the viewer to see images clearly whether they are in the stereoscopic region or not, thereby improving viewing versatility while maintaining stereoscopic effect reliability.
3Object-affected harmful factors
If the left eye image and right eye image are not respectively delivered to the left eye and right eye of the viewer exactly and properly, then the viewer may feel uncomfortable or dizzy, but ensuring exact delivery requires precise position determination
Solution Approach 1:
The detection device continuously monitors the viewer's position and provides feedback to the control device. This feedback loop enables the system to accurately determine whether the viewer is in the appropriate position for stereoscopic viewing and adjust the image delivery accordingly, ensuring exact delivery of left and right eye images to the respective eyes while preventing discomfort and dizziness.

AI summary
A display method of a two-dimensional and naked eye type stereoscopic switchable display device is disclosed. The two-dimensional and naked eye type stereoscopic switchable display device includes a two-dimensional and naked eye type stereoscopic switchable display module, at least one detection device and an indicator device. The two-dimensional and naked eye type stereoscopic switchable display module provides a plurality of stereoscopic image regions in a naked eye type stereoscopic display mode. Then, detect a viewer's position with the detection device. And, determine whether or not the viewer's position is in the stereoscopic image regions with the two-dimensional and naked eye type stereoscopic switchable display device. When the viewer locates in the stereoscopic image regions, the indicator device emits a first color light. When the viewer locates outside of the stereoscopic image regions, the indicator device emits a second color light.
