Title:
SUBLIMATION PURIFICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/051307
Kind Code:
A1
Abstract:
The invention relates to an apparatus for purifying OLED materials by sublimation. Conventional sublimation purification apparatuses are batch type, where one sublimation purification process is performed by loading one source material into the processor chamber, and then unloading a purified material from the process chamber. These processes are manually performed, and thus it is not possible to continuously produce purified materials for OLED. Therefore, it is difficult to increase throughputs and productivity. According to the invention, loading the source materials and unloading the purified materials is performed automatically, thus enabling a continuous process of purifying source materials for OLED.
