    • An evaporator for vaporizing an organic material to be deposited on a flexible substrate where the evaporator includes an evaporation tube having a wall encompassing a cavity for vaporizing the organic material, at least one heating device arranged adjacent to the wall and being adapted to heat the evaporation tube, and at least one nozzle assembly protruding from the evaporation tube. The nozzle assembly further comprises a nozzle cover with an opening, and a shutter for selectively opening and closing the opening of the nozzle cover. The shutter is adapted to have in operation of the evaporation tube a temperature within a shutter temperature range of 140° C. such that the temperature of the nozzle cover is within the shutter temperature range.
    • 一种用于蒸发要沉积在柔性基底上的有机材料的蒸发器,其中所述蒸发器包括具有包围用于蒸发所述有机材料的空腔的壁的蒸发管,至少一个邻近所述壁布置的加热装置,并适于加热所述蒸发 管,以及从蒸发管突出的至少一个喷嘴组件。 喷嘴组件还包括具有开口的喷嘴盖和用于选择性地打开和关闭喷嘴盖的开口的挡板。 快门适于使蒸发管的操作温度在140℃的快门温度范围内,使得喷嘴盖的温度在快门温度范围内。
