  • Patent number: 11614660
    Abstract: A transmittance-variable film and a use thereof, where the transmittance-variable film can control pretilt of a liquid crystal interface by applying a liquid crystal alignment film containing splay oriented liquid crystal molecules, and can vertically and horizontally orient a liquid crystal layer or a liquid crystal interface according to an average tilt angle of the liquid crystal alignment film to ensure uniformity of driving and fast response speed. In addition, by applying a liquid crystal alignment film, the transmittance-variable film can be implemented in various modes with a simple coating-drying-curing method excluding the rubbing process by controlling an arrangement of liquid crystal molecules in a liquid crystal alignment film other than the pretilt control method using the conventional rubbing method.

  • Publication number: 20220280086
    Abstract: The disclosure provides a method of generating relative pattern information between imitation drawing data. By generating pattern information obtained by digitally analyzing one or more pieces of drawing data of an imitation data group, the generated pattern information may be used to analyze psychological state values of users in the imitation data group. Also, a connection between the psychological state values of the users in the imitation group may be discriminated by generating relative pattern information between N pieces of drawing data, which are similar in shape and color. In addition, the relative pattern information may be analyzed by using a model trained by machine-training.
