Engineering Contradiction Analysis
1Manufacturing precision
If a traditional liquid crystal alignment and curing approach is used for Multi-Mode Glass manufacturing, then the manufacturing process is simple, but alignment incompatibility occurs for liquid crystal panels of different sizes leading to suboptimal pretilt angles and residual images
Solution Approach 1:
The patent applies local quality by providing different liquid crystal compositions with different reactive monomer concentrations to different regions of the glass substrate according to the specific properties (pixel density, aperture rate) of liquid crystal panels to be manufactured in each region, thereby achieving optimal alignment for each panel type without requiring complex alignment devices
Solution Approach 2:
The patent changes the chemical composition parameters of the liquid crystal material by adjusting the reactive monomer concentration in different liquid crystal compositions to match the specific requirements of different panel types, enabling precise control of pretilt angles and eliminating alignment incompatibility issues
2Productivity
If liquid crystal panels of different sizes are manufactured on a single glass substrate using MMG approach, then glass substrate utilization rate increases, but alignment incompatibility arises due to different pixel density and aperture rate requirements
Solution Approach 1:
The patent segments the glass substrate into multiple regions, with each region designated for manufacturing a specific type of liquid crystal panel. Different liquid crystal compositions are applied to different regions according to the panel type, enabling high-utilization MMG manufacturing while maintaining alignment compatibility for each panel size and specification
Solution Approach 2:
The patent creates a universal liquid crystal composition system that can serve multiple panel types with different specifications. By formulating different liquid crystal compositions with varying reactive monomer concentrations, a single manufacturing process can accommodate multiple panel sizes and requirements, achieving both high substrate utilization and alignment compatibility

AI summary
A liquid crystal dropping device is provided. A machine table is divided into at least two regions and a liquid crystal dropping nozzle is disposed corresponding to each of the regions. Liquid crystal compositions provided by the liquid crystal dropping nozzles corresponding to the regions are different when liquid crystal panels of different properties are placed in respective regions. In such a way, during manufacturing products of different sizes on a same substrate, performance of each product can meet standards.
