Display Panel Liquid Crystal Blocking for Uniform On-Board Visuals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized on-board display panels experience liquid crystal aggregation due to gravity, acceleration, and high-temperature, leading to non-uniform display quality, especially when the vehicle is in motion.
Innovation Solution
A display panel is divided into multiple sub-regions using liquid crystal blocking components, such as parallel and perpendicular strips, which act as photo spacers to prevent liquid crystals from flowing between regions, improving display uniformity and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display panel uses a large area to meet on-board display requirements, then the display size is increased, but liquid crystals are prone to aggregate at partial regions due to gravity and acceleration
Solution Approach 1:
The display panel is divided into multiple independent display regions through liquid crystal blocking components (such as liquid crystal blocking strips or blocking holes). Each region contains a separate liquid crystal layer that is isolated from adjacent regions, preventing liquid crystal aggregation across the entire panel while maintaining large overall display area.
2Adaptability or versatility
If the display panel is fixed vertically in a vehicle, then the display can be mounted in standard vehicle configurations, but liquid crystals aggregate at partial regions due to gravity and acceleration
Solution Approach 1:
By segmenting the liquid crystal layer into isolated regions using blocking components, the patent enables vertical mounting adaptation while preventing gravity-induced aggregation. Each segmented region maintains uniform liquid crystal distribution independently, allowing the display to function properly in vertically mounted vehicle configurations.
3Quantity of substance
If the display panel uses a large amount of liquid crystals to fill the large area, then the display coverage is improved, but liquid crystals aggregate at partial regions
Solution Approach 1:
The liquid crystal layer is segmented into multiple isolated regions by blocking components. This allows a large total amount of liquid crystals to be used across the entire panel while each individual region maintains uniform distribution, preventing aggregation even with high liquid crystal quantities.
4Stability of the object's composition
If the display panel is divided into multiple regions using liquid crystal blocking components, then liquid crystal aggregation is prevented, but the device complexity increases
Solution Approach 1:
Liquid crystal blocking components serve as intermediary elements between adjacent liquid crystal regions. These components (strips or holes) are simple structural additions that effectively isolate liquid crystal regions and prevent aggregation without requiring complex mechanical or electronic systems.
