The organic matter co-evaporation is a mixed evaporation method in which organic matters are respectively ejected from a main evaporation source and a doping evaporation source and uniformly mixed and evaporated in a certain ratio in the same range of a substrate.
However, since the main evaporation source and the doping evaporation source are separately provided, it is very difficult to mix and evaporate organic materials at a certain ratio, and in order to overcome such a difficulty, efforts have been made to shorten the distance separating the main evaporation source and the doping evaporation source.
When the substrate is evaporated, if one evaporation source cannot achieve the desired evaporation thickness, a plurality of evaporation sources are used, but it is difficult to control the organic matters in the plurality of evaporation sources to be uniformly evaporated to the same range of the substrate; in order to overcome such difficulties, efforts are being made to shorten the distance separating each of a plurality of evaporation sources.
In the prior art, the baffle plate for opening and closing the opening part is arranged at the tops of the evaporation sources, and the baffle plate is linearly moved or rotated at the upper part of the evaporation sources, but in the prior art, the baffle plate for opening and closing the opening part of the evaporation sources is arranged at the upper part of the evaporation sources, when the opening parts of the evaporation sources are required to be completely opened in use, the baffle plate is moved to the outermost part of the evaporation sources so that the opening parts of the evaporation sources are all opened, but when one or two of the evaporation sources are required to be opened, because the distance for separating the evaporation sources is shortened, when the baffle plate is moved, no redundant area at the top of the evaporation source positioned at the middle position in the evaporation sources can accommodate the baffle plate, and the position of the baffle plate can block other evaporation sources for evaporation.
When it is necessary to perform a vapor deposition process on an evaporation source at a specific position or simultaneously perform a vapor deposition process using a plurality of evaporation sources, since the respective distances separating the plurality of evaporation sources are shortened, when the evaporation sources are freely used, the shutter plate cannot completely avoid the opening portions of the evaporation sources when moving, which may affect the vapor deposition of the substrate by the evaporation sources.
