Array Substrate Data Line Segmentation for High-Frequency Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-domain liquid crystal displays face challenges in achieving high-frequency drive and reducing power consumption due to the need for different pixel voltages, which often results in reduced charging time and increased power consumption when using the same data line for pixel voltage signals with different polarities.
Innovation Solution
The array substrate design includes multiple display domains per pixel, each connected to a switch device and arranged with specific polarity configurations for data and gate lines, allowing for independent voltage control and opposite polarities between adjacent pixels, enabling a dot-inversion drive mode with reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same data line is used to provide pixel voltage signals with different polarities in time-sharing mode, then the device complexity is reduced, but the charging time period of the pixel is reduced and high-frequency drive cannot be achieved
Solution Approach 1:
The patent divides the data line configuration into multiple independent data lines (first data line and second data line) that can simultaneously provide voltage signals with different polarities to different display domains within the same pixel. This segmentation eliminates the need for time-sharing and allows parallel charging of multiple domains, thereby increasing the charging time period and enabling high-frequency drive.
2Device complexity
If the same data line is used to provide pixel voltage signals with different polarities, then the device complexity is reduced, but power consumption increases
Solution Approach 1:
By segmenting the data line configuration into multiple independent data lines, each line can be optimized to provide voltage signals of a specific polarity only when needed. This eliminates the need to repeatedly switch polarities through a single data line, reducing unnecessary power consumption while maintaining simplified overall device complexity.
3Productivity
If multiple data lines are provided between every two columns of pixels, then high-frequency drive is enabled, but the device complexity increases
Solution Approach 1:
The patent applies local quality by providing multiple data lines specifically between adjacent pixel columns where different polarities are needed, while using a single data line at the edges of pixel columns where only one polarity is required. This localized approach to multi-data-line configuration enables high-frequency drive in critical areas without unnecessarily increasing device complexity across the entire display.
