    Abstract: A patterning device performs patterning in manufacture of a display panel in which thin films including an organic film are laminated above a substrate. The patterning device includes a chamber, light transmissive plates, and a laser emitter. The chamber has a light transmissive window including a first light transmissive plate through which a laser beam is transmitted and accommodates a thin film laminated substrate. A second light transmissive plate through which the laser beam is transmitted is in the chamber between the first light transmissive plate and the thin film laminated substrate at a position spaced away from the thin film laminated substrate. The laser emitter is outside the chamber and emits the laser beam towards the thin film laminated substrate, through the first light transmissive plate and the second light transmissive plate, to irradiate and remove a portion of the thin film.

  • Patent number: 11986961
    Abstract: A machine learning model operation management system includes a model building server and an operation server. The model building server builds a trained machine learning model based on received training data. When the trained machine learning model stored in a robot controller operates for determining the operation of a robot, the operation server receives operation information generated by the robot controller. Data of the trained machine learning model built by the model building server is assigned with model identification information that uniquely identifies the trained machine learning model. The robot controller makes an external inquiry as to whether or not it has permission to use the trained machine learning model stored in itself, and if it has the permission to use, it makes the trained machine learning model available for use. The operation server stores the operation information in association with the model identification information.
