Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lenticular lens is used to display stereoscopic images, then the display device can provide three-dimensional viewing experience, but the viewing angle is limited and display quality is restricted
Solution Approach 1:
The patent segments the viewing experience by dividing M view images corresponding to M different viewing spaces and converting each into N stereoscopic images with different directional characteristics. This segmentation allows multiple discrete viewpoints to be provided, effectively expanding the overall viewing angle while maintaining image quality for each segment
Solution Approach 2:
The patent adds a temporal dimension to the display system by temporally dividing M view images and sequentially displaying them. This temporal multiplication approach (M×N stereoscopic images) expands the viewing experience in time rather than requiring simultaneous display of all images, thereby increasing viewing angle without compromising the precision of individual image rendering
2Adaptability or versatility
If multiple stereoscopic images are displayed simultaneously to increase viewing angle, then more viewpoints are provided, but the device complexity increases
Solution Approach 1:
The patent employs periodic action by temporally dividing M view images and displaying them in sequential cycles. Each view image is converted into N stereoscopic images that are displayed in a periodic sequence, allowing multiple viewpoints to be provided over time without requiring all images to be displayed simultaneously, thus avoiding the complexity of simultaneous multi-image display systems
Solution Approach 2:
The patent creates multiple copies of the same view image content but with different directional characteristics (N copies per view image). These copied images are then distributed to different viewing spaces temporally, providing multiple viewpoints without requiring fundamentally different display hardware for each viewpoint, thereby controlling system complexity
3Adaptability or versatility
If the display panel displays more images to increase viewing angle, then the viewing experience is enhanced, but the refresh rate and response time are affected
Solution Approach 1:
The patent applies dynamics by adaptively managing the temporal display of M×N stereoscopic images based on the display panel's capabilities. The system dynamically adjusts the refresh rate and timing of image display to accommodate the increased number of images while maintaining acceptable performance, allowing the viewing angle to be enhanced without completely sacrificing refresh rate

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 approach significantly increases the viewing angle and display quality of stereoscopic images by allowing M×N stereoscopic images to be viewed from different perspectives, improving the overall 3D imaging experience.
Implementation Method 1
The optical lens assembly converts the view image displayed on the display panel into N stereoscopic images in which directions of the view images are different from each other to emit the converted view image toward a viewing space

AI summary
A stereoscopic image display device includes a display panel and an optical lens assembly. The display panel includes a plurality of pixels. The display panel temporally divides M view images corresponding to M viewing spaces to display the temporally divided image on a display panel. ‘M’ is a natural number of no less than two. The optical lens assembly converts the view image displayed on the display panel into N stereoscopic images in which directions of the view images are different from each other to emit the converted view image toward a viewing space corresponding to the view image displayed on the display panel. ‘N’ is a natural number no less than two.
