Partitioned Liquid Crystal Display Panel for Dropping Irregularity Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The liquid crystal material dropping method for manufacturing liquid crystal display panels faces challenges in maintaining consistent dropping quantities, leading to irregularities and reduced manufacturing yield rates, especially in large-sized panels, which increases production costs.
Innovation Solution
The introduction of a partition member that creates small, spatially independent regions within the display panel allows for precise control of liquid crystal material distribution by either creating a vacuum or filling these regions, enabling correction of defects such as gravitational shift and wipe displacement through controlled movement of excess or deficient material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid crystal material dropping method is used for manufacturing large-sized liquid crystal display panels, then the manufacturing process can be simplified compared to vacuum sealing, but irregularities in dropping quantity occur leading to reduced manufacturing yield rate
Solution Approach 1:
The patent divides the liquid crystal display panel into multiple regions using partition members. Each region can be independently filled with liquid crystal material, allowing for localized control and correction of dropping quantity irregularities. This segmentation enables precise adjustment of liquid crystal material distribution in each region without affecting the entire panel.
2Productivity
If the dropping quantity of liquid crystal material is not precisely controlled, then the manufacturing process remains simple, but irregularities among individual products occur causing display characteristics to differ
Solution Approach 1:
The patent implements local quality control by creating distinct regions within the liquid crystal display panel using partition members. Each region can have its liquid crystal material filling independently optimized, allowing local adjustment of material quantity to achieve uniform display characteristics across the entire panel while maintaining overall manufacturing efficiency.
3Area of stationary object
If the area of the liquid crystal display panel is increased for large-sizing, then the display device meets modern requirements, but it becomes more difficult to restrict irregularities in dropping quantity
Solution Approach 1:
The patent applies segmentation by dividing large-sized liquid crystal display panels into multiple smaller regions using partition members. This allows the liquid crystal material filling process to be controlled in smaller, more manageable units, thereby maintaining precise dropping quantity control even in large-sized panels and improving overall manufacturing precision.

AI summary
The present invention restricts the fluctuation of a gap among individual display devices. The display device includes two substrates which are arranged to face each other in an opposed manner with a liquid crystal material therebetween, an annular sealing material which is arranged on peripheries of the substrates, a first region which includes an image display region, and a second region which is separated from the first region by the partition member.
