Pixel Structure Layout for Uniform RGB Light Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD pixel structures with RGB arrangements suffer from poor light mixing effects, leading to abnormal displays, particularly in purple screens, due to non-adjacent red and blue sub-pixels causing reddish and bluish anomalies.
Innovation Solution
A pixel structure where red and blue sub-pixels in adjacent first pixel sets are arranged non-adjacent to each other, while being adjacent within each set, and optionally supplemented with additional sub-pixels to improve light mixing, maintaining the same display area.

Engineering Contradiction Analysis
1Shape
If red and blue sub-pixels are arranged non-adjacent in conventional RGB layout, then each pixel set can be clearly defined, but light mixing effect deteriorates causing reddish and bluish anomalies
Solution Approach 1:
The patent segments the pixel array into multiple scanning zones, with different arrangement patterns applied to different zones. Odd scanning lines use one arrangement pattern while even scanning lines use another, allowing optimized light mixing in each zone while maintaining overall pixel definition
Solution Approach 2:
The patent introduces a new dimension of arrangement by considering both horizontal and vertical positioning across multiple scanning lines. By alternating patterns between odd and even scanning lines, it creates a multi-dimensional arrangement that improves light mixing while preserving pixel set clarity
2Ease of operation
If red and blue sub-pixels are arranged adjacent within each pixel set, then light mixing improves, but adjacent pixel sets may cause color contamination
Solution Approach 1:
The patent divides the display into multiple scanning zones and applies different arrangement patterns to odd and even scanning lines. This segmentation allows adjacent red and blue sub-pixels within each pixel set for improved mixing, while the zone-based differentiation prevents color contamination between adjacent pixel sets
Solution Approach 2:
The patent applies different arrangement patterns to different local zones (odd vs even scanning lines). Each zone has optimized local arrangement for its specific function: some zones prioritize light mixing while others prioritize preventing color contamination, achieving both goals simultaneously across the whole display

AI summary
A pixel structure and a display panel. The pixel structure includes a plurality of first pixel sets arranged in an array along a first direction and a second direction, each first pixel set includes at least three sub-pixels of different colors, and at least three of the sub-pixels are a red sub-pixel, a green sub-pixel and a blue sub-pixel. Between two adjacent first pixel sets, the red sub-pixel in one first pixel set and the blue sub-pixel in another first pixel sets arranged adjacent to this one in the first direction are arranged non-adjacent to each other, and the red sub-pixel and the blue sub-pixel in each first pixel set are arranged adjacent to each other. The display panel includes the above pixel structure.
