  • Patent number: 10629840
    Abstract: The present invention provides an organic optoelectronic device and a method for manufacturing the same, in which laser scanning is used to form the electrical connection between the second electrode layer and the contact electrode layer. The present invention can effectively decrease the frequency of replacement of metal masks, significantly shorten the time required for replacing the metal masks, and reduce the down time due to the replacement of metal masks. In addition, the organic optoelectronic device can have a large active area due to the narrow border of the electrical connection formed by the laser scanning.
