Sub-pixel Arrangement for Display Color Fringing Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in achieving high picture quality due to color fringing, which is not effectively addressed by the conventional arrangement of sub-pixels.
Innovation Solution
The proposed solution involves arranging sub-pixels in specific modes, such as inserting a first or third sub-pixel between every two second sub-pixels, and deploying these modes alternately in different directions, along with compensation and mapping of image data using specific parameters to improve pixel arrangement and reduce color fringing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional sub-pixel arrangement (equal numbers of red, green, blue sub-pixels in each direction) is used, then manufacturing is simple and device structure is standard, but color fringing occurs and picture quality deteriorates
Solution Approach 1:
The patent applies asymmetry by arranging sub-pixels in non-uniform patterns where the number of red, green, and blue sub-pixels are deliberately made unequal in specific regions. This asymmetric arrangement optimizes color distribution to reduce color fringing while maintaining acceptable manufacturing complexity through systematic patterns.
Solution Approach 2:
The patent implements local quality by applying different sub-pixel arrangement strategies to different regions of the display. Specific arrangements are used in certain areas to address local color fringing issues, while other regions use different patterns, allowing optimized picture quality in problem areas without uniformly increasing overall complexity.
2Manufacturing precision
If sub-pixels are arranged to reduce color fringing, then picture quality improves, but the arrangement complexity increases
Solution Approach 1:
The patent segments the display into different regions with specific sub-pixel arrangement patterns. By dividing the display area and applying targeted arrangements in specific segments, the patent reduces color fringing in problem areas while keeping other areas simpler, thereby managing overall complexity.
Solution Approach 2:
The patent changes the arrangement parameters (positions, densities, and distributions of red, green, and blue sub-pixels) to optimize color fringing reduction. By adjusting these parameters systematically rather than using fixed complex patterns, the patent achieves improved picture quality with controlled complexity.
3Ease of manufacture
If equal numbers of primary color sub-pixels are used in each direction, then device structure is simple and manufacturing is easy, but color fringing cannot be effectively reduced
Solution Approach 1:
The patent deliberately introduces asymmetry in sub-pixel arrangements, using unequal numbers of red, green, and blue sub-pixels in specific regions. This asymmetric design effectively reduces color fringing while maintaining systematic patterns that do not overly complicate manufacturing processes.
Solution Approach 2:
The patent applies local quality optimization by using different sub-pixel arrangements in specific regions where color fringing is problematic, rather than uniformly complicating the entire display structure. This allows targeted improvement of color fringing control without unnecessarily increasing overall manufacturing complexity.
