Engineering Contradiction Analysis
1Area of moving object
If a rotating display screen is used to achieve 360-degree stereoscopic vision, then the field angle and viewing coverage are improved, but the resolution and image quality may deteriorate due to the rotation and sequential display of multiple two-dimensional images
Solution Approach 1:
The patent transitions from traditional 2D planar display to a rotating 3D spatial display system. The display screen rotates around a vertical axis, transforming the display from a static two-dimensional surface to a dynamic three-dimensional structure that can present images from multiple angles simultaneously, thereby achieving 360-degree stereoscopic vision without compromising resolution through the use of high-resolution display panels
Solution Approach 2:
The patent employs a rotating display screen that can dynamically adjust its rotation speed and angular position. The rotation speed is controlled to match the human visual persistence threshold, creating a dynamic display system that maintains high resolution while achieving comprehensive viewing coverage. The system can switch between different rotation speeds and stop positions to optimize both resolution and field angle according to different viewing scenarios
2Loss of information
If sequential display of multiple two-dimensional images is used to render three-dimensional graphics, then the completeness of three-dimensional representation is improved, but the time required for display and refresh rate may worsen
Solution Approach 1:
The patent implements periodic rotation of the display screen at carefully controlled intervals. The rotation period is designed to match the human visual persistence threshold (typically 24-60 Hz), allowing the system to sequentially display multiple two-dimensional images from different angles while maintaining the perception of continuous three-dimensional content. This periodic action ensures that all views are presented within a single visual persistence cycle, preventing information loss while maintaining high refresh rates
Solution Approach 2:
The patent maintains continuous rotation of the display screen without interruption, ensuring that the sequential display of multiple two-dimensional images flows smoothly. The rotation speed is optimized to keep the entire sequence within the human visual persistence duration, creating a continuous perception of three-dimensional graphics without noticeable interruptions or delays, thereby maintaining both completeness and high effective refresh rate
3Illumination intensity
If optical assembly is added to adjust emergent light into collimated light, then the light control and viewing angle are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent introduces an optical assembly as an intermediary component between the display screen and the viewer. This optical assembly includes light control elements such as collimating lenses or optical waveguides that transform the divergent light from the display panel into collimated light beams. The intermediary optical components enable precise light direction and viewing angle control while maintaining a relatively simple overall structure, as the optical assembly can be integrated into the existing display housing without requiring complete system redesign
