Display Panel Subpixel Arrangement for Image Artifact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices experience image artifacts due to poor symmetry between blue and white sub-pixels, leading to suboptimal performance in pixel units.
Innovation Solution
The display panel is arranged with a matrix of sub-pixels where each pixel unit includes one complete red and one complete green sub-pixel, along with half-sized blue and white sub-pixels shared between adjacent units, ensuring better symmetry and alternating arrangements to minimize artifacts.

Engineering Contradiction Analysis
1Reliability
If conventional display devices use complete blue and white sub-pixels in a 2:2:1:1 ratio, then the device structure is simple and manufacturing is easier, but poor symmetry between blue and white sub-pixels causes image artifacts
Solution Approach 1:
The patent divides the display panel into different types of pixel units (first type with blue sub-pixel, second type with white sub-pixel) and further segments each pixel unit into multiple sub-pixels (red, green, blue/white). This segmentation allows asymmetric sub-pixel types to be arranged in a structured manner that achieves symmetry at the pixel unit level, reducing image artifacts while maintaining manufacturing feasibility.
Solution Approach 2:
The patent intentionally uses asymmetric sub-pixel configurations within pixel units - the first pixel units have blue sub-pixels while the second pixel units have white sub-pixels. This controlled asymmetry at the sub-pixel level creates overall symmetry at the pixel unit level when arranged in alternating patterns, resolving the image artifact problem while maintaining design flexibility.
2Ease of manufacture
If blue and white sub-pixels are arranged without symmetry consideration, then the manufacturing process is simpler, but image artifacts are introduced due to poor symmetry
Solution Approach 1:
The patent creates equipotentiality by ensuring that blue and white sub-pixels are distributed symmetrically across the display panel through alternating pixel units. Each sub-pixel type occupies equivalent positions in its respective pixel unit type, creating a balanced optical field that eliminates the harmful image artifacts while maintaining simple manufacturing processes.
3Device complexity
If complete blue and white sub-pixels are used in conventional ratios, then the device structure is straightforward, but symmetry between adjacent pixel units is poor leading to artifacts
Solution Approach 1:
The patent merges blue and white sub-pixels into a unified pixel unit structure where they alternate in a regular pattern. By combining different sub-pixel types into coordinated pixel units (first type with blue, second type with white) and arranging these units alternately, the patent achieves symmetry between adjacent pixel units while maintaining a straightforward device structure that is easy to manufacture.
