Deposition apparatus and method for manufacturing organic light emitting diode display using the same |
摘要 |
A deposition apparatus includes: a deposition source including a spray nozzle linearly arranged in a first direction and discharging a deposition material; and a pair of angle control members disposed at both sides of the deposition source and controlling a discharging direction angle of the deposition material. Each angle control member includes a rotation axis parallel to the first direction, and a plurality of shielding plates installed about the rotation axis and separated from each other by a predetermined interval around the rotation axis. Although the deposition angle is changed according to the increasing of the process time, the deposition angle is compensated to form a uniform thin film. Also, the organic thin film may be uniformly deposited through each pixel of an organic light emitting diode (OLED) display, thereby increasing luminance uniformity for each pixel. |
