Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gratings are arranged on one side or both sides of a 2D display panel to provide 3D display effect, then 3D display capability is achieved, but resolution is sharply decreased and calculating amount of rendering is sharply increased
Solution Approach 1:
The patent introduces a new dimension by arranging gratings obliquely at specific angles rather than parallel to the display panel surface. This oblique arrangement creates a third spatial dimension in the grating structure, allowing light to be directed to multiple viewpoints while maintaining pixel resolution. The grating edges are positioned at angles that enable simultaneous projection of image information to multiple viewing angles without requiring reduction in pixel density.
Solution Approach 2:
The patent changes the geometric parameters of the grating arrangement, specifically the angle and orientation of grating edges relative to the display panel. By adjusting the inclination angle and positioning of grating edges, the system optimizes the distribution of light to multiple viewpoints while maintaining high resolution. This parameter optimization allows the same pixel array to serve multiple viewpoints without resolution loss.
2Manufacturing precision
If high definition display is maintained in N-viewpoint 3D display device, then display quality is improved, but transmission bandwidth and computing resources are multiplied by N times
Solution Approach 1:
The patent merges multiple viewpoint images into a single composite image that is displayed on the 2D panel. Instead of transmitting separate high-resolution images for each viewpoint, the system combines all viewpoint information into one image that contains encoded spatial information. The oblique grating arrangement then spatially separates this combined image into multiple viewpoints during display, reducing transmission bandwidth while maintaining high definition for each viewpoint.
Solution Approach 2:
The patent creates a single master image that serves as a template for all viewpoints. This master image is processed once and then optically copied to multiple viewpoints through the grating structure. Instead of generating and transmitting N separate high-resolution images, the system generates one master image that is then distributed to N viewpoints through optical copying via the oblique gratings, significantly reducing computational and transmission overhead.
3Adaptability or versatility
If gratings are arranged parallel to display panel to provide 3D effect, then 3D display is achieved, but multiple times of format adjustment and display adaptation are required
Solution Approach 1:
The oblique grating arrangement creates a universal display structure that can simultaneously serve multiple viewpoints and different display formats. The specific angular configuration of the gratings allows the same physical structure to handle various image formats and viewpoint configurations without requiring format adjustment mechanisms. This multi-functional design eliminates the need for separate adaptation systems for different display scenarios.
