Patent ID: 8901810

Claim:
A device, comprising: a first substrate layer and a second substrate layer, at least one of said first and said second substrate layers being electrically conductive; and at least a first organic light emitting device (OLED) assembly and a second OLED assembly arranged between said first and said second substrate layers, wherein each of said first and second OLED assemblies comprises a first electrically conductive layer, a second electrically conductive layer and an organic light emitting layer arranged between said first and said second electrically conductive layers, wherein the first electrically conductive layer, the organic light emitting layer, and the second electrically conductive layer are stacked upon each in a stack direction and each of the first and second OLED assemblies extends from the first substrate layer to the second substrate layer in a height direction which is perpendicular to the stack direction, and wherein each of said first and said second OLED assemblies is arranged such that its height direction forms a non-zero angle in relation to at least one of said first and said second substrate layers.
