Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If liquid crystal droplets are uniformly distributed with same weight, then the manufacturing process is simple, but sealing puncture, edge gap, and bubble issues occur reducing product quality
Solution Approach 1:
The patent applies different liquid crystal amounts to different spatial locations: the rim area receives a first liquid crystal amount while the central area receives a second liquid crystal amount. This local differentiation ensures that droplets in the rim area diffuse to the plastic frame edges without causing sealing puncture, while central droplets maintain proper spacing to avoid edge gap and bubble issues, thereby resolving the contradiction between manufacturing simplicity and distribution uniformity.
2Ease of manufacture
If gap between liquid crystal droplet and plastic frame is too small, then dripping process is simple, but sealing puncture occurs after diffusion
Solution Approach 1:
The patent specifically increases the liquid crystal amount for droplets in the rim area compared to the central area. This local enhancement ensures that rim droplets have sufficient volume to diffuse and fill the gap between the plastic frame and the liquid crystal cell, maintaining sealing integrity without requiring complex adjustment of droplet spacing or positioning.
3Reliability
If gap between liquid crystal droplet and plastic frame is too large, then sealing puncture is avoided, but edge gap and bubble issues occur
Solution Approach 1:
The patent applies a larger liquid crystal amount specifically to rim area droplets, enabling them to diffuse sufficiently to reach and fill the gap with the plastic frame. This localized increase in droplet volume ensures that the diffusion distance can be larger without causing edge gap or bubble issues, thereby maintaining both sealing integrity and distribution uniformity.
4Quantity of substance
If liquid crystal amount of single droplet is increased, then diffusion coverage is improved, but non-uniform distribution occurs
Solution Approach 1:
The patent implements a differentiated droplet volume strategy where rim area droplets receive a first liquid crystal amount and central area droplets receive a second liquid crystal amount. This spatial variation in droplet size ensures that rim droplets achieve sufficient diffusion coverage to fill gaps with the plastic frame, while central droplets maintain appropriate spacing and uniformity, preventing non-uniform distribution across the entire liquid crystal cell.

AI summary
The present disclosure relates to a formation method of liquid crystal layers, a liquid crystal panel, and a liquid crystal dripping device. A first dripping is applied toward a central area of the plastic frame of a first substrate, and a second dripping is applied toward a rim area of the plastic frame of a second substrate, wherein a liquid crystal amount of a single droplet with respect to the first dripping and the second dripping are different. That is, the dripping process applied to one substrate may be adjusted in accordance with the diffused result of the liquid crystals on the other substrate, such that the uniformity of the diffused liquid crystals may be enhanced. In addition, the issues, such as sealing puncture, edge gap, and bubble, may be avoided so as to enhance the product quality.
