Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic image display devices suffer from distortion and luminance deviation issues due to the use of lenticular lenses that are slanted at a predetermined angle, leading to visible patterns and reduced image quality.
Innovation Solution
A stereoscopic image display device with a display panel featuring a specific arrangement of pixels and lenses, where pixels of different colors are arranged in intersecting directions and lenses extend in a direction perpendicular to the pixel arrangement, preventing vertical image distortion and color moire phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenticular lenses are disposed slanted at a predetermined angle on the display panel, then stereoscopic images can be separated into multi-views, but vertical image distortion occurs
Solution Approach 1:
The patent applies asymmetry by arranging pixels in units with different color configurations in different spatial positions. Specifically, odd-numbered units have a different color arrangement pattern compared to even-numbered units, creating an asymmetric pixel layout that compensates for the distortion caused by slanted lenticular lenses while maintaining multi-view stereoscopic separation
Solution Approach 2:
The patent implements local quality by applying different color arrangement rules to different regions of the display panel. Odd-numbered pixel units use one color arrangement pattern while even-numbered units use another pattern, allowing each local region to be optimized for its specific position relative to the lenticular lens orientation, thereby reducing overall vertical distortion
2Adaptability or versatility
If lenticular lenses are used to separate stereoscopic images, then multi-view functionality is achieved, but luminance deviation is magnified and visible patterns appear
Solution Approach 1:
The asymmetric arrangement of pixel colors in different units helps distribute luminance variations more evenly across the display. By alternating color patterns between odd and even units, the invention prevents concentrated luminance deviations that would otherwise be magnified by the lenticular lenses, reducing visible patterns while preserving multi-view functionality
Solution Approach 2:
Different color arrangement strategies are applied to different local regions (odd vs. even units) to locally compensate for luminance deviations. This localized optimization ensures that each region's color distribution is tailored to its position, minimizing visible patterns and luminance artifacts when viewed through the lenticular lens system
3Ease of manufacture
If pixels are arranged in a standard grid pattern, then manufacturing is simplified, but color moire phenomena occur with slanted lenticular lenses
Solution Approach 1:
The invention introduces asymmetry into the pixel arrangement by creating different color patterns for odd and even units. This breaks the regular symmetry of standard grid patterns, preventing the formation of moire patterns when viewed through slanted lenticular lenses, while still maintaining a relatively simple manufacturing process based on repeating unit patterns
Solution Approach 2:
The display panel is segmented into multiple pixel units with different color arrangement patterns. By dividing the display into odd-numbered and even-numbered units with distinct patterns, the invention prevents large-scale moire phenomena while maintaining manageable manufacturing complexity through the repetitive nature of the segmented patterns
