Staggered Pixel-Island 3D Display Layout for Wide Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current super multi-view 3D light field display apparatuses have limited viewing angles, making them unsuitable for large-sized or medium-sized displays, and struggle to provide high-resolution, continuous visual experiences without generating moire patterns or black areas.
Innovation Solution
A display apparatus featuring a staggered arrangement of pixel islands with sub-pixels and a light-splitting assembly of lenses, where each light-splitting repeating unit has two lenses covering light-emitting sub-pixels, ensuring close contact of main lobe viewing angles and eliminating black areas by continuous emission and precise lens positioning, along with a light shielding layer to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional light field display apparatus is used, then the display can provide three-dimensional visual effects, but the viewing angle is limited and moire patterns appear
Solution Approach 1:
The display panel is divided into multiple pixel islands with staggered arrangements, and the light field lens array is segmented into repeating units with multiple lenses. This segmentation allows each lens to control light from specific pixel columns, enabling precise viewing angle control and eliminating moire patterns through the staggered configuration.
Solution Approach 2:
The patent introduces a vertical dimension to the pixel arrangement by staggering pixel islands in the row direction while maintaining column alignment. This dimensional change allows light from adjacent pixel columns to be directed to different spatial locations, expanding the viewing angle and preventing moire interference patterns.
2Area of stationary object
If the display size is increased for large-sized displays, then the display area is improved, but the viewing angle coverage becomes insufficient
Solution Approach 1:
The light field lens array is divided into repeating units, where each unit contains multiple lenses corresponding to multiple pixel columns. This segmentation allows the system to scale to large display areas while maintaining consistent viewing angle coverage through the repetitive modular structure.
Solution Approach 2:
The light field lens repeating unit serves multiple functions: it controls light from multiple pixel columns, creates multiple viewpoints, and maintains viewing angle consistency across the entire display. This multi-functionality allows large-sized displays to achieve comprehensive viewing angle coverage without sacrificing image quality.
3Measurement precision
If the resolution is increased to provide high-resolution display, then the image quality is improved, but black areas appear in the display
Solution Approach 1:
Each lens in the light field lens repeating unit is positioned to receive light from specific pixel columns with precise local positioning. This local quality control ensures that high-resolution pixel information is directed to appropriate viewpoints without creating black areas, as each region of the display is optimized for its specific function.
Solution Approach 2:
The staggered pixel island arrangement combined with the light field lens repeating units ensures continuous light emission across the entire display area. By overlapping the light emission regions from adjacent pixel columns through the lens system, the patent eliminates black areas while maintaining high resolution.
4Ease of manufacture
If pixel islands are arranged in a regular grid pattern, then the manufacturing is simplified, but the viewing angle and resolution are limited
Solution Approach 1:
The pixel array is segmented into pixel islands with staggered row arrangements, while maintaining regular column alignment. This segmentation approach preserves manufacturing simplicity through standardized pixel island structures while achieving enhanced viewing angle and resolution through the staggered configuration.
Solution Approach 2:
The patent introduces asymmetry in the row direction by staggering odd and even rows of pixel islands relative to each other, while maintaining symmetry in the column direction. This selective asymmetry improves viewing angle and resolution without significantly complicating the manufacturing process, as the column-aligned boundaries remain regular.
