Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to generate cell array images in light field display, then three-dimensional display functionality is achieved, but computational complexity and processing time increase significantly
Solution Approach 1:
The patent divides the image generation process into multiple stages: first generating a pixel light field information database, then processing slice images at different depth positions, and finally superimposing recorded images to create the microcell array image. This segmentation reduces computational complexity at each stage while maintaining overall three-dimensional display functionality.
Solution Approach 2:
The patent performs preliminary processing by generating a pixel light field information database before actual image generation. This pre-computed database contains essential light field information that accelerates subsequent image processing steps, reducing the time required for generating cell array images while preserving three-dimensional display capabilities.
2Loss of information
If conventional methods are used to generate cell array images, then complete light field information is captured, but computational burden increases
Solution Approach 1:
The patent extracts only the essential light field information needed for three-dimensional display by generating a pixel light field information database that contains key parameters. This extraction approach maintains sufficient light field information completeness for effective 3D display while significantly reducing computational energy consumption compared to processing complete light field data.
3Manufacturing precision
If detailed processing of slice images at multiple depth positions is performed, then image quality is improved, but processing complexity increases
Solution Approach 1:
The patent segments the complex image processing task into manageable components: slice image processing at different depth positions, recording individual image layers, and superimposing them to form the final microcell array image. This segmentation maintains high image quality through detailed processing while reducing perceived system complexity by organizing operations into distinct, manageable stages.

AI summary
A light field display method includes: generating a pixel light field information database (S1); processing, according to different depth positions of an original three-dimensional image, slice images corresponding to the different depth positions and pixel light field information at the different depth positions, to obtain recorded images of the slice images of the original three-dimensional image at the different depth positions (S2); and superimposing the recorded images of the slice images of the original three-dimensional image at the different depth positions, to obtain a microcell array image of the original three-dimensional image (S3). A light field display system has a database generator (101), a recorded image generator (102), and a superimposer (103) which implement the described functions.
