AI Technical Summary

Problems solved by technology

The laser beam removes the impurity, but it can also damage the area around the impurity
Such damage can provide a channel for moisture or oxygen to penetrate into the pixel, thus reducing the lifetime of the OLED

Embodiment Construction

[0030] Certain embodiments will now be described with reference to the figures.

[0031] image 3 is a top view of a unit pixel of an organic light emitting display (OLED) according to an embodiment. see image 3 , setting the data line 10 , the scan line 20 and the common voltage line 30 . The scan lines 20 cross and are insulated from the data lines 10 . The common voltage line 30 crosses and is insulated from the scan lines 20 . The common voltage line 30 extends parallel to the data line 10 . The data lines 10, scan lines 30, and common voltage lines 30 define unit pixels. The lines can be arranged randomly, or they can be arranged in different ways.

[0032] The unit pixel includes a switching thin film transistor 40 , a driving thin film transistor 50 , a capacitor 60 and an organic light emitting diode 80 . The switching thin film transistor 40 is driven by a scan signal applied to the scan line 20 . The switching thin film transistor 40 is used to transmit the ...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2005-0080331 filed Aug. 30, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to an organic light-emitting display (OLED) and a manufacturing method thereof, in particular to an OLED having a pixel electrode structure allowing laser repair and minimizing device damage and a manufacturing method thereof. Background technique [0004] Among flat panel displays (FPDs), an organic light emitting display (OLED) is an emissive device with a wide viewing angle and a response speed of about 1 ms or faster. Also, OLEDs can be manufactured in a small thickness at low cost and have good contrast, so they have attracted much attention as next-generation flat panel displays. [0005] Such OLEDs typically include an anode, a cathode and an emissive layer disposed between these two electrodes. ...
