Display Panel Scan-Line Layout for Lower Data Line Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display panels suffer from poor overall display effects due to high load on data lines and significant light-emitting differences between sub light-emitting pixels, especially when the number of rows of sub light-emitting pixels is large.
Innovation Solution
A display panel design with scanning lines and data lines arranged at an included angle, where each light-emitting component includes three data lines and two light-emitting units, and the number of scanning lines is less than the number of sub light-emitting pixels, allowing for increased data lines and reduced load per line, thereby minimizing light-emitting differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of rows of sub light-emitting pixels is increased, then the display resolution is improved, but the load on data lines increases and light-emitting uniformity deteriorates
Solution Approach 1:
The patent divides the display panel into multiple light-emitting components, each containing multiple light-emitting units. This segmentation allows the data lines to be distributed across multiple components, reducing the number of sub light-emitting pixels connected to each individual data line. Specifically, each light-emitting component includes multiple light-emitting units with shared data lines, creating a hierarchical structure that reduces the load per data line while maintaining high overall resolution.
Solution Approach 2:
The patent introduces a new organizational dimension by arranging light-emitting units and components in a multi-level hierarchy beyond the simple row-column pixel grid. By creating light-emitting components that group multiple light-emitting units, and light-emitting units that group multiple sub light-emitting pixels, the system adds a dimensional layer to the data line distribution, allowing more efficient load management across the display panel.
2Reliability
If the number of data lines is increased, then the light-emitting uniformity is improved, but the device complexity increases
Solution Approach 1:
The patent makes data lines universal by having them serve multiple light-emitting units within a light-emitting component. Each data line is shared across multiple sub light-emitting pixels through the hierarchical structure of light-emitting units and components. This multi-functionality reduces the total number of data lines needed compared to a traditional one-to-one mapping, thereby reducing device complexity while maintaining uniform light-emitting performance.
Solution Approach 2:
The patent merges multiple sub light-emitting pixels into light-emitting units, and multiple light-emitting units into light-emitting components. This merging strategy allows multiple pixels to share common data lines, reducing the overall data line count. The hierarchical merging structure optimizes the balance between data line quantity and light-emitting uniformity by combining pixels in a controlled manner that maintains performance while reducing complexity.
Data Source
AI summary
The embodiments of present the application disclose a display panel. The display panel includes a substrate disposed with a plurality of scanning lines and a plurality of data lines. A light-emitting component includes three scanning lines and two light-emitting units, and a light-emitting unit includes a plurality of sub light-emitting pixels. A number of the data lines is less than a number of the sub light-emitting pixels in the light-emitting unit, and a product of the number of the data lines and the number of the scanning lines is greater than or equal to the number of the sub light-emitting pixels. By electrically connecting the two light-emitting units with the three scanning lines, a load of the data lines is reduced and display effects are improved.
