Zigzag Subpixel Arrangement for Diagonal Color Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subpixel arrangements in displays often compromise color presentation capability, particularly in the diagonal direction, and are inefficient in terms of manufacturing complexity and resource utilization.
Innovation Solution
The implementation of zigzag subpixel groups and subpixel repeating groups, where each zigzag subpixel unit includes a plurality of subpixels of the same color arranged in a zigzag pattern, allowing for full color presentation in any direction without increasing the number of addressable display elements, thus reducing manufacturing complexity and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If each pixel is divided into three strip subpixels or four quadrate subpixels to present full color, then color presentation capability is improved, but the number of addressable display elements increases and manufacturing complexity increases
Solution Approach 1:
The patent extracts the white subpixel from the traditional RGB or RGBW configuration, using only three subpixels (R, G, B) per pixel. The white subpixel is removed because human vision is more sensitive to color than brightness, and the remaining three subpixels can adequately provide color information when combined with subpixel rendering algorithms.
Solution Approach 2:
The patent changes the arrangement parameters of subpixels by introducing a repeating group pattern (e.g., RGGB or GRBG) instead of traditional strip or quadrate arrangements. This parameter change allows for reduced subpixel count while maintaining color presentation through strategic positioning and rendering algorithms.
2Ease of manufacture
If subpixels are arranged in traditional strip or quadrate patterns, then manufacturing is simplified, but color presentation capability in diagonal direction is compromised
Solution Approach 1:
The patent employs asymmetric subpixel arrangements within the repeating groups, where subpixels are positioned in non-uniform patterns (e.g., staggered rows with alternating color sequences). This asymmetry compensates for diagonal viewing angles and improves color presentation in all directions while maintaining manufacturability through regular repeating patterns.
Solution Approach 2:
The patent transitions from one-dimensional strip arrangements to two-dimensional repeating group patterns that extend across both horizontal and vertical dimensions. This dimensional change allows color information to be distributed more effectively in all directions, including diagonals, while maintaining a regular manufacturing pattern.
3Measurement precision
If more subpixels are used to increase apparent resolution, then display resolution is improved, but resource usage and power consumption increase
Solution Approach 1:
The patent uses subpixel rendering algorithms that create virtual copies of subpixel information through interpolation and pattern recognition. Instead of physically increasing the number of subpixels, the system copies and redistributes color information across adjacent subpixels to achieve higher apparent resolution while using fewer physical display elements, thereby reducing power consumption.
4Manufacturing precision
If subpixels with different shapes and sizes are used to achieve specific patterns, then color presentation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the display into repeating groups of subpixels with standardized shapes and sizes. Each group contains a specific pattern of R, G, and B subpixels that can be manufactured using uniform processes. This segmentation into regular, repeatable units simplifies manufacturing while the strategic arrangement within each group maintains color presentation capability.
