Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High concentrations of free impurity ions in liquid crystal display devices lead to flicker, FLK value drift, and image sticking, affecting the display quality due to uncontrollable contamination and movement of these ions during the manufacturing and display processes.
Innovation Solution
A liquid crystal display panel design incorporating a first and second electrode generating an electric field and a conductor between them to create a magnetic field perpendicular to the substrates, which moves and fixes impurity ions onto the film layers, reducing their concentration in the liquid crystal layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional liquid crystal display manufacturing is used, then production efficiency is maintained, but free impurity ions accumulate in the liquid crystal layer causing flicker and image sticking
Solution Approach 1:
The patent applies magnetic field treatment to the liquid crystal layer during manufacturing. The magnetic field causes impurity ions to aggregate and precipitate out of the liquid crystal layer, converting the harmful mobile ions into benign stationary aggregates that can be removed or held harmless, thus improving display stability without compromising production efficiency
Solution Approach 2:
The patent introduces magnetic field parameters (strength, direction, duration) as a new control variable in the liquid crystal manufacturing process. By applying a magnetic field with specific parameters, the physical state of impurity ions is changed from dispersed mobile state to aggregated stationary state, reducing their harmful effects on display performance
2Reliability
If magnetic field treatment is applied to reduce impurity ions, then display quality improves, but device structure becomes more complex
Solution Approach 1:
The patent integrates the magnetic field generation function into existing components of the liquid crystal display panel. The same electrode structure that generates electric fields for liquid crystal switching is also configured to generate magnetic fields during a preliminary treatment stage, making the existing components serve dual functions and avoiding additional complex structures
Solution Approach 2:
The patent applies magnetic field treatment during the manufacturing process before the display is assembled and put into service. This preliminary action removes or aggregates impurity ions before they can cause display defects, so that the final display product has improved quality without requiring complex additional components in the finished device
