Multi-Primary Pixel Dot Matrix for Single-Column Color Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RGB stripe displays require at least 2 columns to form a white color, as each column lacks all necessary colors, limiting the efficiency of multi-color displays.
Innovation Solution
An image device with pixel groups arranged in a predetermined matrix form, including at least one first, second, third, and fourth color dot, allowing for repeated sequences of these dots in both row and column directions, enabling the formation of all multi-primary colors in a single row or column using subpixel rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional RGB stripe display uses one column per color, then each column contains only one color, but at least 2 columns are needed to form white color
Solution Approach 1:
The pixel structure is segmented into multiple subpixels (R1, G1, B1, W1) within each pixel group, allowing different color components to be distributed across subpixels rather than requiring separate columns for each color. This segmentation enables white color formation within a single column by combining multiple subpixels.
Solution Approach 2:
The patent transitions from a one-dimensional column-based color organization to a two-dimensional pixel group structure with multiple subpixels arranged in rows and columns. This dimensional change allows colors to be organized both horizontally (across subpixels in a pixel group) and vertically (across pixel groups), enabling white color formation within a single column through vertical stacking of colored subpixels.
2Adaptability or versatility
If RGB pixel groups are arranged in row direction only, then all colors are available in each pixel group, but column direction lacks color diversity
Solution Approach 1:
Each pixel group is designed to contain all necessary color subpixels (R, G, B, W) that can function independently or in combination. This universal design allows the same pixel group structure to serve multiple purposes: displaying individual colors, combining colors to form white, and maintaining color diversity in both row and column directions simultaneously.
Solution Approach 2:
The patent merges multiple color subpixels (R1, G1, B1, W1) within each pixel group and combines adjacent pixel groups to ensure that both row and column sequences contain complete color sets. This merging approach allows a single column to contain all colors by stacking pixel groups vertically, while maintaining the ability to display individual colors through selective subpixel activation.
