OLED DEVICE AND MANUFACTURE THEREOF

摘要

The invention describes a method of manufacturing an OLED device (1). This method comprises the steps of providing an electrically conductive carrier substrate (3) with a first carrier surface (3a) and a second carrier surface (3b), assembling at least the first carrier surface (3a) a patterned layer of insulating material (5) over an integral area, the layer of insulating material (5) being patterned by a plurality of holes (7) such that an electric access to the first carrier surface (3a) is possible from an upper surface (10) of the layer of insulating material (5) facing away from the first carrier surface (3a), assembling a patterned conductive coating (8, 9) on the insulating material (5) at its upper surface (10) such that the conductive coating (8, 9) enters the holes (7) and covers the insulating material (5) over an integral area, whereby the conductive coating (9) is patterned such that a number of discrete first electrode areas (11) are formed in the conductive coating (9), applying an organic light-emitting layer (13) above at least one first electrode area (11), applying a second electrode layer (15) above the organic light emitting layer (13). The invention also describes a semi-finished product (21) in such process and an OLED device (1) manufactured in such process.
