Liquid Crystal Display Barrier Ribs View Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal displays face challenges in achieving a narrow view angle without the use of a view angle limitation film or pixels, which are either difficult to manufacture, expensive, or result in reduced light transmittance.
Innovation Solution
The implementation of barrier ribs formed on the upper substrate within sub-pixels to limit the view angle, eliminating the need for a separate view angle limitation film or pixels, and allowing for the formation of a liquid crystal layer between the substrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a view angle limitation film is arranged separately in front of the liquid crystal panel, then the view angle can be limited, but the manufacturing complexity increases and light transmittance is reduced
Solution Approach 1:
The patent merges the view angle limitation function with the liquid crystal panel structure by forming barrier ribs directly on the upper substrate within sub-pixels. This integration eliminates the need for a separate view angle limitation film, thereby reducing manufacturing complexity while maintaining effective view angle control.
Solution Approach 2:
The patent extracts the view angle limitation function from a separate film component and incorporates it into the panel structure itself through barrier ribs. This extraction eliminates the additional film layer, reducing manufacturing steps and improving light transmittance by removing the extra interface.
2Object-affected harmful factors
If view angle limitation pixels are formed within the liquid crystal panel, then the view angle can be limited, but light transmittance is reduced
Solution Approach 1:
The barrier ribs are formed locally within sub-pixels rather than as separate pixels, creating a localized view angle control mechanism. This local quality approach allows view angle limitation without the need for additional pixel structures that would block light, thereby maintaining high light transmittance.
3Object-affected harmful factors
If a separate view angle limitation film is used, then view angle can be controlled, but manufacturing difficulty increases and cost increases
Solution Approach 1:
The view angle limitation function is merged into the panel manufacturing process itself through the formation of barrier ribs on the upper substrate. This eliminates the need for a separate view angle limitation film and its associated manufacturing steps, thereby improving ease of manufacture and reducing cost.
