Abstract

The present invention provides an organic optoelectronic device and method for manufacturing the same. The method deposits the organic layer and the second electrode layer in the same range, and laser scans the second electrode layer at a plurality of first predetermined locations to form electrical connections between the second electrode layer and the contact electrodes. The present invention can effectively reduce the number of times for metal mask positioning and replacement to significantly reduce the manufacturing time and decrease the contamination resulted from the replacement of the metal mask. Besides, the electrical connection formed by laser scanning can connect a plurality of organic optoelectronic components in series and arrange them side by side. The present invention can be applied to organic optoelectronic device, such as OLED devices and OPV devices.

First claim

What is claimed is:

depositing an electrode layer on a substrate; forming a plurality of spacers in the electrode layer, wherein the plurality of spacers divide the electrode layer into a plurality of first electrodes and a plurality of contact electrodes; depositing an organic layer on the first electrodes, the spacers, and the contact electrodes through a metal mask; depositing a second electrode layer on the organic layer through the metal mask; laser scanning the second electrode layer at a plurality of first predetermined locations to remove a portion of the second electrode layer, the organic layer, and the contact electrode and at a plurality of second predetermined locations to remove a portion of the second electrode layer, the organic layer, and the spacer simultaneously; and electrically connecting the second electrode layer to the contact electrodes at the plurality of first predetermined locations, respectively.

2 . The method of claim 1 , further comprising depositing at least one connection electrode connecting the first electrode and the contact electrode.

3 . The method of claim 1 , wherein the organic layer has the same deposition range as the second electrode layer.

4 . The method of claim 1 , wherein the laser scanning uses a laser wavelength of 1064 nm and a power of less than 3 W.

5 . An organic optoelectronic device composed of a plurality of organic optoelectronic components connected in series and arranged side by side, comprising:
a substrate; a plurality of first electrodes and a plurality of contact electrodes separated by a plurality of spacers on the substrate; an organic layer provided on the first electrodes, the spacers, and the contact electrodes; and a second electrode layer provided on the organic layer and electrically connected to the contact electrodes.

6 . The organic optoelectronic device of claim 5 , wherein the electrical connection between the second electrode layer and the contact electrode is formed by laser scanning.

7 . The organic optoelectronic device of claim 6 , wherein the electrical connection between the second electrode layer and the contact electrode is transparent.

8 . The organic optoelectronic device of claim 6 , further comprising at least one connection electrode connecting the first electrode and the contact electrode.
