<p>The invention provides an OLED that includes a planar substrate having a first side, a second side, a recess and one or more positioning notches. Further, the OLED also includes a first electrode layer provided on the first side of the planar substrate. The OLED also includes one or more light emitting layers on the first electrode layer and a second electrode layer provided on the one or more light emitting layers. The OLED also includes one or more first electrical contacts and one or more second electrical contacts, such that they are alternately placed around a periphery of the recess and form an annular arrangement proximal to the periphery. Further, according to the invention, the one or more first electrical contacts are in contact with the first electrode layer and the one or more second electrical contacts are in contact with the second electrode layer.</p> |
