Array Substrate Additional Data Lines for Response Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pixel density in TFT-LCD displays leads to a large number of gate lines, resulting in signal delay and reduced response speed due to progressive scanning of subpixels, which adversely affects display quality.
Innovation Solution
The introduction of secondary data lines that allow simultaneous scanning and signal input to multiple gate lines, reducing signal delay by enabling simultaneous data signal transmission to subpixels across different rows, thereby improving response speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of gate lines is increased to achieve high pixel density, then the display resolution is improved, but the response speed is reduced due to progressive scanning delays
Solution Approach 1:
The patent divides the data signal transmission path into two separate paths: original data lines and additional data lines. By segmenting the transmission system, multiple gate lines can receive data signals simultaneously through different paths, eliminating the progressive scanning delay while maintaining high pixel density display capability
Solution Approach 2:
The patent introduces an additional dimension to the data signal transmission by adding parallel data transmission paths (additional data lines) alongside the original data lines. This dimensional expansion allows simultaneous data delivery to multiple gate lines, resolving the time delay issue caused by sequential scanning
2Device complexity
If progressive scanning of gate lines is used to simplify control, then the device complexity is reduced, but the transmission speed of data signals is reduced
Solution Approach 1:
The control system is segmented into two independent but coordinated control paths: one controlling original data lines and another controlling additional data lines. This segmentation allows parallel data transmission while maintaining relatively simple control logic through the use of control signals that manage the two paths
Solution Approach 2:
The patent merges the functionality of multiple data transmission paths into a unified system where original data lines and additional data lines work together. By combining these paths, the system achieves high-speed parallel transmission while keeping control complexity manageable through integrated signal management
