masking to the application of steam, organic material of an organic light-emitting diode

摘要

The present invention provides a masking to the application of steam, organic material of an organic light-emitting diode, which is a masks - frame, cover plates on opposite end edges of the masks - frame are arranged in such a way that it leads to a vapor deposition - side, and a mask, which is positioned on the cover plates. The masks - frame has a rectangular shape and has a central region, which forms a rectangular receiving opening, the size of the receiving opening by means of a setting, the at positions of the cover plates is carried out, is variable. In the mask, a plurality of openings, which are distributed uniformly over the mask are. The masking has a mask having a uniform mass distribution, in order, while the magnetic attraction of the mass of a temporal inconsistency of the attraction of different zones of the mask and thus a resulting displacement of the position of pixels to avoid.
