OLED FLEXIBLE OLED PANEL FOR LIGHTING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

According to the present invention, a flexible OLED panel for a lighting device comprises: a substrate made of a polymer material having a first light extraction pattern on a lower surface thereof; an auxiliary wiring pattern arranged on the substrate; a first electrode arranged on the substrate on which the auxiliary wiring pattern is arranged; a passivation layer arranged on the first electrode, wherein the passivation layer is disposed on at least a region where the auxiliary wiring pattern is arranged; an OLED light emitting structure arranged on the first electrode on which the passivation layer is arranged; a second electrode arranged on the OLED light emitting structure; and an encapsulation layer arranged on the second electrode. According to the present invention, the flexible OLED panel for a lighting device can have flexibility by using a substrate made of a polymer material, can improve light extraction efficiency through a light extraction pattern, and can easily detach an auxiliary substrate by using the techniques of bonding and detaching between the substrate and the auxiliary substrate using an adhesive.
