First Claim
Patent Images
1. A method of fabricating an organic light emitting device (OLED) panel having an arbitrary shape, the method comprising:
- obtaining a first OLED panel comprising a plurality of layers, the layers including a substrate, an anode, a cathode, and an emissive organic stack;
making a first cut in the first OLED panel on a first shape outline, wherein the first cut does not extend through at least one layer of the first OLED panel; and
making a second cut in the first OLED panel, wherein the second cut extends through each of the plurality of layers of the first OLED panel.

Abstract
OLED panels and techniques for fabricating OLED panels are provided. Multiple cuts may be made in an OLED panel to define a desired shape, as well as the location and shape of external electrical contacts. The panel may be encapsulated before or after being cut to a desired shape, allowing for greater flexibility and efficiency during manufacture.

28. An organic light emitting device (OLED) comprising:
-
a cathode comprising; a central first region; and a second region adjacent to an exterior edge of the OLED, the second region being separated from the first region by an ablated cathode region; an anode electrically connected to the second region; and an organic emissive stack disposed between the cathode and the anode.

29. A method of fabricating an OLED panel, the method comprising:
-
obtaining an OLED blank without defined external electrical connections and having a first shape; and cutting the OLED blank to a second shape different than the first shape to form an OLED panel having the second shape; wherein the step of cutting the OLED blank to the second shape defines a plurality of external electrical connections for the OLED panel. - View Dependent Claims (30)
