Pixel Arrangement Reduces Color Shift in 3D Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pattern retarder glasses based 3D display systems experience significant color shift issues at large view angles, leading to a deterioration in display quality and market competitiveness due to the regular arrangement of pixels, which causes red/blue color shifts when viewed from different angles.
Innovation Solution
A pixel arrangement method that divides primary pixels into sub-pixels of different colors, arranged in check patterns or vertical configurations, with a color correction algorithm circuit to regulate color homogeneity, ensuring that adjacent sub-pixels in either horizontal or vertical directions are of different colors, thereby eliminating the regular pixel arrangement and color shift problems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pixels are arranged in a regular pattern with pixels of the same color at borders, then the display structure is simple and easy to manufacture, but color shift occurs at large view angles causing deterioration of display quality
Solution Approach 1:
Each primary pixel is segmented into multiple sub-pixels (three or four sub-pixels) with different colors (red, green, blue, and optionally white). This segmentation allows adjacent sub-pixels to have different colors, eliminating the regular same-color pattern that causes color shift at large view angles, while maintaining manufacturing feasibility through standardized sub-pixel structures.
Solution Approach 2:
The patent applies different color configurations to different regions of the display panel. Specifically, pixels at the top and bottom borders use different color arrangements than interior pixels, with border pixels configured to prevent color shift when viewed from upward or downward angles. This local differentiation ensures optimal display quality across all viewing angles while maintaining overall manufacturing simplicity.
2Manufacturing precision
If pixels are arranged to prevent color shift at large view angles using different color patterns, then display quality is improved, but the pixel arrangement complexity increases
Solution Approach 1:
The patent employs asymmetric color arrangements in border pixels compared to interior pixels. Border pixels use specific color configurations (e.g., different combinations of red, green, blue, and white sub-pixels) that are asymmetric relative to the standard interior pixel pattern. This asymmetry effectively prevents color shift at large view angles while the overall structure remains systematic and manageable.
Solution Approach 2:
The sub-pixel structure serves multiple functions: it enables color display in both 2D and 3D modes, prevents color shift at various viewing angles, and maintains compatibility with existing display technologies. The same sub-pixel building blocks are used throughout the panel, providing universality that reduces complexity despite the sophisticated color arrangement requirements.
