Display Device Data Line Segmentation for Delta Subpixel Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In delta-arranged subpixel configurations, adjacent subpixels of different colors connected to the same data line increase the driving load, leading to potential display failures.
Innovation Solution
The display device incorporates island-shaped subpixels with specific light-emitting layers and subpixel circuits, where subpixels of the same color are connected to the same data line, reducing the driving load and improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If subpixels are delta-arranged with adjacent subpixels of different colors connected to the same data line, then the data line can be shared and device complexity is reduced, but the driving load of the data line increases
Solution Approach 1:
The invention segments the data lines by color, creating separate data lines for red, green, and blue subpixels. This segmentation ensures that each data line drives only subpixels of the same color, thereby reducing the capacitive load on each data line while maintaining the delta-arranged subpixel configuration.
Solution Approach 2:
The invention applies local quality by assigning different data lines to different color groups of subpixels. Each data line is optimized for its specific color group, allowing for reduced driving load on each individual data line while maintaining overall system functionality.
2Device complexity
If subpixels are delta-arranged with adjacent subpixels of different colors connected to the same data line, then device complexity is reduced, but display failures occur due to increased driving load
Solution Approach 1:
The invention segments the data lines by color, creating separate data lines for red, green, and blue subpixels. This segmentation reduces the capacitive load on each data line, preventing charging inadequacies and reducing display failures while maintaining the delta-arranged subpixel configuration.
Solution Approach 2:
The invention uses multiple separate data lines that can be independently managed and replaced if needed, rather than relying on a single high-load data line configuration that is prone to failure.
