LCD Array Substrate Electrode Segmentation for Uniform LC Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display devices, the complex distribution of electric fields between strip-shaped and planar electrodes leads to difficulties in deflecting liquid crystal molecules uniformly, resulting in black disclination lines and suboptimal display quality.
Innovation Solution
The array substrate design includes strip-shaped electrodes with first and second parts extending in different directions, where the second parts are disconnected at the second side, optimizing the electric field distribution to reduce harmful components and improve liquid crystal molecule rotation, thereby avoiding black disclination lines and enhancing display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If strip-shaped electrodes are used in liquid crystal display devices, then the display area can be increased, but the electric field distribution becomes complex leading to black disclination lines and suboptimal display quality
Solution Approach 1:
The strip-shaped electrode is segmented into a first section extending in a first direction and a second section extending in a second direction different from the first direction. This segmentation allows the electrode to generate electric field components in multiple directions, enabling uniform deflection of liquid crystal molecules across the display area while avoiding the formation of black disclination lines.
2Object-affected harmful factors
If strip-shaped electrodes with complex geometry are used to improve liquid crystal molecule rotation, then display quality improves, but manufacturing precision requirements increase
Solution Approach 1:
The electrode structure implements local quality by having different sections extend in different directions. The first section extends in a first direction to provide primary electric field component, while the second section extends in a second direction to provide additional electric field component. This local variation in electrode orientation optimizes liquid crystal molecule rotation at different regions without requiring high overall manufacturing precision.
