Abstract: The invention relates to a sublimation purification apparatus and a method for purifying a material for an organic light-emitting diode (OLED). 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 the purified material for the OLED. Therefore, it is difficult to increase a throughput and productivity. According to the invention, loading the source material and unloading the purified material are performed automatically, thus enabling a continuous process of purifying the source material for the OLED.
