Position be equipped with 121 (not shown in figure 1) of baffle plate assembly.Baffle plate assembly 121 is used to be opened so that organic material in vapor deposition
It can be deposited to glass substrate, and be closed so that after the completion of vapor deposition the organic material deposition for continuing evaporation after the completion of vapor deposition
To baffle plate assembly 121.Wherein, baffle plate assembly 121 can be controlled by control device 200.Such as: when evaporated device 120 enters
Chamber 111 is deposited and glass substrate is with after the completion of the contraposition of high-precision metal mask plate, control device 200 controls baffle plate assembly 121
It opens, at this moment organic material can be deposited by high-precision metal mask plate to glass substrate.Alternatively, baffle plate assembly 121
It can be controlled by positioning mechanism, control signal be sent to baffle plate assembly 121 after positioning mechanism contraposition is completed, to control baffle group
Part 121 is opened.After the completion of organic material vapor deposition, after evaporated device 120 is moved in cooling chamber 114, control device 200 is controlled
Baffle plate assembly 121 processed is closed, and at this moment since the temperature of heating source is still higher, is had a small amount of organic material and is continued to evaporate, but
It is the presence due to baffle plate assembly 121, so that the organic material evaporated later will deposit on baffle plate assembly 121, to subtract
The organic material for depositing to interior lining is lacked, it is possible to reduce the number of more changeable liner.
Specifically, baffle plate assembly 121 can be realized using the mechanical component that tradition can be automatically opened or closed, example
