Abstract
An organic light emitting diode display includes a substrate, a display pixel unit that displays an image, the display pixel unit being on the substrate, and a dummy pixel unit near the display pixel unit on the substrate. The display pixel unit includes a first electrode on the substrate, an organic emission layer on the first electrode, and a second electrode on the organic emission layer. The dummy pixel unit includes a second electrode formed on the substrate and does not include an organic emission layer.
Claims13
An organic light emitting diode display, comprising:
- a substrate;
- a display pixel unit that displays an image, the display pixel unit being on the substrate;
- and
- a dummy pixel unit near the display pixel unit on the substrate,
- wherein the display pixel unit includes:
- a first electrode on the substrate;
- an organic emission layer on the first electrode;
- and
- a second electrode on the organic emission layer, and
- the dummy pixel unit includes a second electrode formed on the substrate and does not include an organic emission layer.
A method for manufacturing an organic light emitting diode display, the method comprising:
- providing a substrate including a display pixel area that displays an image and a dummy pixel area formed near the display pixel area;
- forming a first electrode on the substrate in the display pixel area;
- forming a pixel definition layer defining a pixel area on the first electrode in the display pixel area;
- dripping an emission material and a solvent dissolved with the emission material onto the display pixel area;
- dripping a solvent without the emission material onto the dummy pixel area on the substrate;
- drying the substrate onto which the emission material and the solvent are dripped;
- and
- forming a second electrode in the display pixel area and the dummy pixel area on the substrate.
