Abstract: A printing screen method includes: providing at least one printing scraper assembly, wherein the printing scraper assembly has a printing scraper and a pressure sensing feedback system; placing at least one printing screen on a substrate; detecting and supplying a pressure value between the printing scraper and the printing screen during printing by the pressure sensing feedback system; and comparing the supplied pressure value and a predetermined pressure value, and changing the pressure between the printing scraper and the printing screen if a difference between the feedback pressure value and the predetermined pressure value is larger than a predetermined threshold. An imprinting apparatus implementing the printing screen method is also provided.

Abstract: An evaporator and a method for adjusting levelness of an evaporator are provided. The evaporator includes: a first platform; a second platform; a distance measuring assembly configured to measure a plurality of first distances between the first platform and a top of a vacuum chamber accommodating the evaporator, and/or a plurality of second distances between the first platform and the second platform; a driving assembly configured to drive the first platform and/or the second platform; and a data processing assembly electrically connected to the distance measuring assembly and the driving assembly, and configured to control the driving assembly to adjust levelness of the first platform according to the measured plurality of first distances, and/or to control the driving assembly to adjust levelness of the second platform according to the measured plurality of second distances.
