Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies for mobile terminals struggle to maintain an optimal viewing experience due to limitations in viewing angle and distance, leading to reduced visual effect and potential dizziness, especially in multi-user scenarios where users outside a narrow angle range do not receive the best 3D effect.
Innovation Solution
A 3D image display method using millimeter wave signals to detect and track users' orientations and distances, adjusting display parameters such as light-emitting angle, view angle, and grating intervals in real-time to ensure each user receives a tailored 3D image, improving immersion and reducing ghosting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed viewing angle range is used for 3D display, then the 3D imaging effect is optimized for users within that range, but users outside this range experience reduced visual effect and visual errors
Solution Approach 1:
The patent implements dynamic adjustment of display parameters including light-emitting angle, view angle, and grating intervals based on real-time user position and orientation detection. The system transitions from a fixed viewing angle configuration to a dynamic one that automatically adapts to user movements, ensuring optimal 3D imaging effect for users at various positions and angles.
Solution Approach 2:
The patent changes multiple display parameters simultaneously (light-emitting angle, view angle, grating intervals) according to detected user feature parameters. By adjusting these parameters dynamically, the system maintains high 3D imaging quality across different viewing conditions and user positions, resolving the contradiction between optimized imaging effect and viewing angle adaptability.
2Adaptability or versatility
If the viewing distance and viewing angle are not appropriately controlled, then the 3D display can be accessed by more users, but the visual effect is greatly reduced and dizziness may arise
Solution Approach 1:
The patent employs millimeter wave detection to continuously monitor user position and orientation, feeding this information back to the display system. Based on this feedback, the system automatically adjusts display parameters to maintain appropriate viewing distances and angles, preventing visual distortion and dizziness while allowing multiple users to access the display.
Solution Approach 2:
The system dynamically adapts display parameters in real-time based on user position detection. When users are detected at inappropriate distances or angles, the system automatically adjusts the light-emitting angle, view angle, and grating intervals to optimize the 3D effect, thereby maintaining visual quality across diverse user positions.
3Adaptability or versatility
If multiple users view the screen simultaneously at different positions, then user coverage is improved, but users in the middle obtain the best 3D effect while users at edges experience visual errors
Solution Approach 1:
The patent applies local quality adjustment by detecting individual user positions and orientations, then customizing display parameters for each user separately. Instead of a uniform display configuration, the system adjusts light-emitting angle, view angle, and grating intervals individually for each user based on their specific position, ensuring consistent high-quality 3D effect for all users regardless of whether they are in the middle or at the edges.
Solution Approach 2:
The system segments the viewing area into different zones corresponding to different users and adjusts display parameters for each zone independently. By detecting multiple users and their respective positions, the system divides the display output into user-specific portions, each optimized for that user's viewing characteristics, thereby eliminating visual errors for edge users.
