Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pixel structures suffer from low color gamut and high power consumption, failing to meet the requirements of high color gamut, low power consumption, and low cost.
Innovation Solution
A pixel structure comprising sub-pixel groups arranged in an array with 6 sub-pixels of different colors in two rows and three columns, where each row forms a square pixel unit using at most two adjacent sub-pixels, reducing data transmission lines and enhancing color gamut, along with a driving method that determines sampling areas and weights for each sub-pixel based on color arrangement orders.

Engineering Contradiction Analysis
1Ease of manufacture
If normal RGB stripe arrangement is used, then the structure is simple and easy to manufacture, but the color gamut is low and power consumption is high
Solution Approach 1:
The pixel is divided into multiple sub-pixels of different colors (R, G, B, C, M, Y) arranged in a specific pattern, with each sub-pixel controlled independently through separate data transmission lines, enabling enhanced color gamut while maintaining manufacturing simplicity
Solution Approach 2:
The patent transitions from traditional linear RGB stripe arrangement to a two-dimensional array arrangement with 6 sub-pixels per pixel, organizing sub-pixels in rows and columns with specific color patterns, thereby expanding color representation capabilities
2Manufacturing precision
If more data transmission lines are used per square pixel unit, then the color control precision is improved, but the device complexity increases
Solution Approach 1:
Adjacent square pixel units share common data transmission lines, where each line serves multiple sub-pixels across neighboring pixels, reducing the total number of transmission lines required while maintaining precise color control through coordinated driving signals
Solution Approach 2:
Data transmission lines are designed to serve multiple functions by controlling sub-pixels across adjacent pixel units, with each transmission line capable of addressing multiple sub-pixels through selective activation, thereby reducing overall line count while preserving color precision
