Oled device with a brightness distribution controlling means

Abstract

The invention describes an OLED device () comprising an active layer () between a first electrode () and a second electrode (); a contact means () for connecting the electrodes () to a power supply (); and a brightness distribution controlling means (), which brightness distribution controlling means () comprises a plurality of openings (), wherein an opening () extends through the second electrode () and the active layer () to expose an area () of the first electrode (); and a plurality of selectively addressable current distribution lines (), wherein a current distribution line () is arranged to extend between a contact means () and an exposed area () such that an electrical connection can be established between the power supply () and the first electrode () to (specifically) regulate the brightness of the active layer () in the vicinity of the exposed area () accessed by that current distribution line (), and whereby the current distribution lines () are electrically connected to each other by means of the first electrode (). The invention further describes an OLED lighting arrangement () comprising such an OLED device (), a line regulation means () for regulating the current flow through a selectively addressable current distribution line () between the contact means () and the first electrode () to regulate the brightness of the active layer () in the vicinity of the exposed area () accessed by that current distribution line (); and a brightness distribution controller () for controlling the line activation means () to address a specific current distribution line (). The invention also describes a method of manufacturing an OLED device () with a brightness distribution controlling means (). The invention also describes a method of controlling the brightness of distribution of such an OLED device in such an OLED lighting arrangement.
