Alternating Pixel Blocks for Uniform Color Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional five-primary-color display panels with subpixels arranged in a matrix result in uneven color distribution due to large spacing between subpixels, leading to an uneven image display.
Innovation Solution
A pixel array is arranged with first and second display blocks alternating in a direction, where subpixels of each block are arranged in two adjacent lines, with gaps between subpixels aligned to extend towards adjacent subpixels in the next line, ensuring concentrated distribution and uniform color display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subpixels are arranged in a matrix with five primary colors in each pixel unit, then color gamut is improved, but subpixels are spaced apart at large distances resulting in uneven color distribution
Solution Approach 1:
The pixel array is divided into first and second display blocks that are arranged alternately. Each display block contains subpixels of different colors arranged in specific patterns, creating a segmented structure that improves both color gamut and color distribution uniformity simultaneously
Solution Approach 2:
The first and second display blocks采用 asymmetric arrangements where the first subpixel, second subpixel, and third subpixel are positioned differently from the fourth subpixel and fifth subpixel. This asymmetric design within the segmented structure optimizes color distribution while maintaining expanded color gamut
2Manufacturing precision
If subpixels are arranged in two adjacent lines within each display block, then color distribution is improved, but gap alignment complexity increases
Solution Approach 1:
Subpixels are arranged in two adjacent lines (first line and second line) within each display block, transitioning from a single-line arrangement to a two-dimensional line structure. This dimensional change improves color distribution while the gap alignment rule provides a simple criterion for managing the increased complexity

AI summary
The present disclosure provides a pixel array, a display device and a display method thereof. The pixel array includes first display blocks and second display blocks arranged in an array. The first display blocks and the second display blocks are arranged by turns in a first direction. Each display block includes a first subpixel, a second subpixel, a third subpixel, a fourth subpixel and a fifth subpixel arranged in two adjacent lines, the first subpixel, the second subpixel and the third subpixel are arranged in a line, and the fourth subpixel and the fifth subpixel are arranged in a line. A gap between any two adjacent subpixels in an ith line is aligned in an extension direction of the gap with a subpixel in an (i+1)th line.
