Pixel Array Sub-Pixel Arrangement for Flat Panel Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pixel arrays in flat panel displays, with equal numbers of red, green, and blue sub-pixels, do not align with human eye vision characteristics, resulting in suboptimal visual effects and the need for more sub-pixels.
Innovation Solution
A pixel array is designed with sub-pixel basic units comprising three red and three green sub-pixels and two blue sub-pixels, arranged such that blue sub-pixels are one for every two pixels in rows and columns, ensuring non-adjacency of red and green sub-pixels, allowing each sub-pixel basic unit to render four pixels with reduced overall sub-pixel count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional RGB-stripe pixel arrangement with equal numbers of red, green and blue sub-pixels is used, then complete color representation is achieved, but the number of sub-pixels increases and visual effect does not match human eye perception
Solution Approach 1:
The patent applies local quality by differentiating the treatment of color sub-pixels based on human visual system characteristics. Specifically, it uses more red and green sub-pixels (which human eyes are more sensitive to) and fewer blue sub-pixels (which human eyes are less sensitive to), creating a non-uniform distribution that optimizes visual perception while reducing total sub-pixel count
Solution Approach 2:
The patent changes the parameter of sub-pixel quantity distribution from equal proportions (1:1:1 RGB) to unequal proportions matching human cone cell ratios. By adjusting the quantity parameters of each color sub-pixel according to human visual sensitivity, the system achieves better visual效果 with fewer total sub-pixels
2Quantity of substance
If equal numbers of red, green and blue sub-pixels are used in each pixel, then color accuracy is maintained, but more sub-pixels are required compared to human eye cone cell proportions
Solution Approach 1:
The patent implements local quality by assigning different quantities of sub-pixels to different colors based on human visual sensitivity. Red and green sub-pixels are given higher quantities while blue sub-pixels have lower quantities, creating a localized optimization that reduces total sub-pixel count while maintaining perceptual color accuracy
Solution Approach 2:
The patent modifies the quantity parameters of sub-pixels from equal distribution to a distribution matching human cone cell proportions. This parameter change optimizes the balance between sub-pixel count and color accuracy by aligning with human visual system characteristics
3Area of stationary object
If red and green sub-pixels are arranged adjacently to maximize space utilization, then area efficiency improves, but visual artifacts may occur due to human eye sensitivity to red and green signals
Solution Approach 1:
The patent applies asymmetry by intentionally separating red and green sub-pixels that are visually sensitive, rather than arranging them symmetrically or adjacently for maximum space utilization. This asymmetric arrangement prevents visual artifacts while still achieving efficient space use through optimized sub-pixel distribution patterns
