Abstract
Official abstract text for this publication.
A first device that may include a short tolerant structure, and methods for fabricating embodiments of the first device, are provided. A first device may include a substrate and a plurality of OLED circuit elements disposed on the substrate. Each OLED circuit element may include a fuse that is adapted to open an electrical connection in response to an electrical short in the pixel. Each OLED circuit element may comprise a pixel that may include a first electrode, a second electrode, and an organic electroluminescent (EL) material disposed between the first and the second electrodes. Each of the OLED circuit elements may not be electrically connected in series with any other of the OLED circuit elements.
First claim
Opening claim text (preview).
1 . A method for producing a device comprising: providing a substrate having a first conductive layer disposed thereon; defining a plurality of physically segmented first electrodes on the first conductive layer, defining a plurality of fuses on the first conductive layer; fabricating a bus line on the substrate; electrically connecting each of the plurality of physically segmented first electrodes to the bus line through the fuses; after fabricating the bus line, depositing an organic EL material over the first electrodes; and depositing a second electrode over the organic EL material. 2 . The method of claim 1 , wherein the first electrodes are anodes. 3 . The method of claim 1 , wherein the plurality of first electrodes and the plurality of fuses comprise the same material. 4 . The method of claim 1 , wherein the plurality of first electrodes and the plurality of fuses are defined simultaneously. 5 . The method of claim 1 , wherein the first conductive layer comprises a transparent conductive oxide.
