Abstract
The present disclosure relates to a manufacturing device and a manufacturing method of OLEDs. The manufacturing device includes a sprayer and a moving unit. The sprayer is arranged above a substrate, and the sprayer includes at least one nozzle configured to ejected ink on a surface of the substrate. The moving unit is configured to control the sprayer to relatively move with respect to the substrate. During an ejecting process of the ink, an ejecting speed of the ink injected by the nozzle includes a first speed weight along a horizontal direction with respect to the surface of the substrate, and a relative moving speed between the sprayer and the substrate comprises a second speed weight along the horizontal direction. The first speed weight is opposite to the second speed weight. As such, the ink may fall within a designated area so as to overcome the ink-jet printing error.
