Pixel Sub-pixel Arrangement Minimizing Moire Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels with two-dimensional arrays of pixels often suffer from visual artifacts like Moire patterns due to uniform sub-pixel arrangements, which affect the quality of color displays.
Innovation Solution
The arrangement of pixel groups in a display panel, where each group consists of four pixels with at least two adjacent color sub-pixels in a specific configuration, allowing for repetitive patterns in rows and columns, reduces the likelihood of Moire patterns by varying the sub-pixel adjacency directions.

1Ease of manufacture
If uniform sub-pixel arrangements are used in conventional display panels, then manufacturing and design are simplified, but visual artifacts like Moire patterns appear affecting display quality
Solution Approach 1:
The patent applies asymmetry by arranging sub-pixels in non-uniform patterns within pixel groups. Specifically, adjacent pixels have different orientations of their sub-pixels (e.g., horizontal vs. vertical arrangements), breaking the symmetry that causes Moire patterns while maintaining manufacturability through systematic design rules.
Solution Approach 2:
The display panel is segmented into multiple pixel groups, where each group contains pixels with different sub-pixel arrangements. This segmentation allows different local patterns to be combined, reducing overall Moire effects while maintaining a regular repeating structure for ease of manufacture.
2Object-affected harmful factors
If varied sub-pixel arrangements are used to reduce Moire patterns, then display quality improves, but device complexity increases
Solution Approach 1:
The patent uses periodic action by repeating the same pixel group pattern across the entire display panel. Each pixel group has a specific arrangement of pixels with varied sub-pixel orientations, and this group repeats periodically in both horizontal and vertical directions, creating a predictable, manageable complexity rather than random complexity.
Solution Approach 2:
The pixel group design serves multiple functions: it reduces Moire patterns through varied arrangements, maintains ease of manufacture through repetition, and provides a systematic framework for different display technologies (LCD, OLED, etc.). The same basic pixel group structure can be adapted to different sub-pixel configurations (RGB, WRGB, etc.).

AI summary
Various arrangements of color sub-pixels in a group of pixels for use in a color display are disclosed. The same group of pixels is repetitively arranged in rows and columns in the color display. In particular, each group of pixels has four pixels arranged on the four quadrants of a rectangle or square. A pixel group may have two sub-pixels in R, two sub-pixels in G, two sub-pixels in B and two sub-pixels in W, but each of the pixels has two different color sub-pixels. In each of the four pixels in a pixel group, the two sub-pixels can be adjacent to each other along the column direction or along the row direction, but the two sub-pixels in at least one pixel are adjacent to each other along the column direction. A pixel group may have two pixels with R, G sub-pixels and two pixels in B.
