Adjustable Stereopsis Depth Display Using Eye-Specific Enable-Signal Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, such as AR glasses, have a predetermined stereopsis depth that cannot be adjusted to accommodate individual user differences in interpupillary distance or depth perception, limiting the flexibility and personalization of the stereoscopic experience.
Innovation Solution
A display device with separate stereopsis depth adjusters for each eye, allowing the output data enable signals to be shifted or delayed relative to the input signals to adjust the position and size of displayed objects, thereby customizing the stereopsis depth based on user-specific parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stereopsis depth is predetermined in display devices, then device complexity is reduced, but adaptability to individual user differences deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of stereopsis depth by introducing adjustable delay stages in the data enable signals for left and right eye images. The delay amounts can be modified according to user-specific parameters such as interpupillary distance, transforming a static predetermined system into a dynamic adaptive one that accommodates individual user differences without requiring complete system redesign
Solution Approach 2:
The patent changes the temporal parameter (delay time) of the data enable signals to adjust stereopsis depth. By varying the delay amount in clock cycles, the system adapts to different user characteristics while maintaining the same hardware structure, thus improving adaptability without proportionally increasing device complexity
2Adaptability or versatility
If stereopsis depth is adjusted for each user, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent achieves multi-functionality by enabling a single display device to serve multiple user profiles with different interpupillary distances and depth perception characteristics. The adjustable delay mechanism allows one device to perform multiple functions (accommodating different users) without requiring separate dedicated hardware for each user configuration
Solution Approach 2:
The patent implements preliminary configuration of user parameters (interpupillary distance, depth perception preferences) before actual use. The system pre-calculates appropriate delay amounts based on user input, allowing quick adaptation without complex real-time adjustments during operation, thus reducing operational complexity
3Adaptability or versatility
If data enable signals are shifted to adjust object position, then stereopsis depth adjustability improves, but signal processing complexity increases
Solution Approach 1:
The patent uses the data enable signal as an intermediary control mechanism to adjust stereopsis depth indirectly. Instead of modifying the image data itself or adding complex depth calculation algorithms, the system uses timing adjustments of the enable signal as a simple mediator to achieve position and depth variation, reducing signal processing complexity

AI summary
A display device includes: a processor for generating first input image data, a first input data enable signal, second input image data, and a second input data enable signal; a first stereopsis depth adjuster for generating first output image data and a first output data enable signal, based on the first input image data and the first input data enable signal; a first sub-display device for displaying a first object, based on the first output image data and the first output data enable signal; a second stereopsis depth adjuster for generating second output image data and a second output data enable signal, based on the second input image data and the second input data enable signal; and a second sub-display device for displaying a second object, based on the second output image data and the second output data enable signal. The first stereopsis depth adjuster shifts the first output data enable signal relative to the first input data enable signal, or the second stereopsis depth adjuster shifts the second output data enable signal relative to the second input data enable signal, and a position of the first object or the second object is adjusted.
