Sub-pixel arrangement structure for high resolution display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The resolution of display devices is limited by the size of sub-pixels, and existing manufacturing processes restrict further improvement in resolution due to process limitations.
Innovation Solution
A sub-pixel arrangement structure that shares sub-pixels among virtual pixels, allowing for increased resolution by arranging first, second, third, and fourth sub-pixels in specific patterns on a substrate, with the third and fourth sub-pixels positioned between and among the first and second sub-pixels, respectively, to form more virtual pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sub-pixel size is reduced to increase resolution, then the number of distinguishable pixels increases, but manufacturing precision requirements become excessively high due to process limitations
Solution Approach 1:
The invention divides the display area into multiple types of pixel units (first pixel units with four sub-pixels, second pixel units with three sub-pixels, third pixel units with two sub-pixels). This segmentation allows different pixel configurations to be used in different regions, enabling high resolution without requiring uniformly tiny sub-pixels across the entire display, thus reducing manufacturing precision requirements.
Solution Approach 2:
The invention introduces a new dimension of pixel unit design by combining multiple sub-pixels into composite pixel units with different configurations (4-sub-pixel, 3-sub-pixel, 2-sub-pixel units). This dimensional change in organizational structure allows the display to achieve high resolution through intelligent arrangement rather than simply reducing individual sub-pixel size, thereby avoiding excessive manufacturing precision demands.
2Ease of manufacture
If traditional sub-pixel arrangement is used, then manufacturing process is simple, but resolution is limited by sub-pixel size and process capabilities
Solution Approach 1:
The display is segmented into different pixel unit types distributed across the display area. This segmentation strategy maintains manufacturing simplicity by using standard sub-pixel components while achieving enhanced resolution through the innovative combination and arrangement of pixel units, without requiring complex manufacturing processes.
Solution Approach 2:
The invention creates pixel units that can serve multiple functions - some pixels are designed for high-resolution display, others for coverage and color accuracy. This multi-functionality allows the display to achieve high resolution without complicating the manufacturing process, as the same basic sub-pixel components are used across different pixel unit types.
3Measurement precision
If sub-pixel size is reduced to improve resolution, then more pixels can be displayed, but the manufacturing process cannot support further resolution improvement
Solution Approach 1:
The display is divided into multiple pixel unit types (first, second, and third pixel units with 4, 3, and 2 sub-pixels respectively) arranged in a systematic pattern. This segmentation approach achieves high resolution through intelligent arrangement of different unit types rather than uniformly reducing sub-pixel size, thereby avoiding excessive device complexity while maintaining manufacturability.
Solution Approach 2:
Different regions of the display use different pixel unit configurations optimized for their specific requirements. This local quality approach allows high resolution in critical areas while maintaining simpler structures elsewhere, balancing resolution improvement with controlled device complexity and ease of manufacturing.
