An organic light emitting diode display includes a p-doped layer that can obtain high efficiency at low-voltage driving and low current and prevent leakage current by differentially forming the p-doped layer for each pixel.

Organic light emitting diode display and method for manufacturing the same

An organic light emitting device that obtains stable image qualities through prevention of any significant decrease in brightness at high temperature. The organic light emitting device includes an anode; a cathode facing the anode; an organic emitting layer interposed between the anode and the cathode; an electron transport layer interposed between the organic emitting layer and the cathode and comprising an alkali metal compound or an alkali earth metal compound; and a buffer layer interposed between the organic emitting layer and the electron transport layer.

Organic light emitting device

An organic light emitting diode display including a substrate, a first electrode on the substrate, a light-emitting layer on the first electrode, a second electrode on the light-emitting layer, and a p-doping layer between the first electrode and the light-emitting layer.

Organic light emitting diode display and manufacturing method thereof

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.
