Organic light emitting display and method of fabricating the same
View Patent ↗An organic light emitting display (OLED) and a method of fabricating the same are provided. The OLED includes: a substrate; a pixel electrode disposed on the substrate and having cells divided into a plurality of cells and cutting patterns connected to the cells; an organic layer having at least an emission layer and disposed on the pixel electrode; and an upper electrode disposed on the organic layer, thereby minimizing the damage of the device and performing laser-repair.
1. An organic light emitting display device (OLED), comprising:
an array of pixels comprising a common electrode common to a plurality of pixels, a plurality of pixel electrodes, and a plurality of organic light-emitting layers, each organic light emitting layer being formed between one of the pixel electrodes and the common electrode;
wherein the plurality of pixels comprises a first pixel including a first pixel electrode, which comprises a conductive layer with a pattern of perforations formed therethrough;
wherein the plurality of pixel electrodes comprises a second pixel electrode, which comprises a conductive layer with a plurality of perforations formed therein, the plurality of perforations generally segmentizing the layer into a plurality of portions, and wherein at least one of the portions is electrically isolated from the rest of the plurality of portions; and
wherein an unwanted conductive particle contacts the at least one portion of the pixel electrode.
2. The device of claim 1 , wherein the unwanted conductive particle further contacts the common electrode.
3. The device of claim 1 , wherein the plurality of pixel electrodes comprises a second pixel electrode, which comprises a conductive layer with a plurality of perforations formed therein, the plurality of perforations generally segmentizing the layer into a plurality of portions, and wherein at least one of the portions is electrically isolated from the rest of the plurality of portions.
4. The device of claim 3 , wherein the at least one electrically isolated portion is substantially shorted to the common electrode.
5. The device of claim 1 , wherein the pattern of perforations forms a plurality of portions in the conductive layer in a square, rectangle, circle, triangle, or polygon shape.
6. The device of claim 1 , wherein the pattern of perforations forms a plurality of portions in the conductive layer that is arranged in a matrix pattern.
7. The device of claim 1 , wherein the plurality of perforations comprises through holes or discontinuous areas formed in the conductive layer.
8. The device of claim 7 , wherein at least part of the through holes or discontinuous areas are elongated.
9. The device of claim 7 , wherein one of the through holes physically separates two neighboring portions formed on both sides thereof, wherein the two neighboring portions are separated by the through hole about 5 μm or less.
10. The device of claim 1 , wherein along an imaginary line formed by linearly arranged perforations, an accumulated distance of the perforations is greater than an accumulated distance of nonperforated areas.
11. The device of claim 1 , wherein the pixel electrode is an anode and the common electrode is a cathode.
12. The device of claim 1 , wherein an organic material is formed into at least part of the plurality of perforations.
13. The device of claim 1 , wherein the perforations are filled with a material different from the conductive layer.
14. The device of claim 1 , wherein each portion in the plurality of portions in the conductive layer is physically connected to another portion in the plurality of portions in the conductive layer on at least one side.
15. The device of claim 1 , wherein each portion in the plurality of portions in the conductive layer is physically connected to another portion in the plurality of portions in the conductive layer on at least two sides.
