Abstract:
1. 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; 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 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; a light emitting area divided into an array of brightness controllable regions and a number of openings assigned to each brightness controllable region; wherein at least one current distribution line extends from the contact means to an exposed area of each brightness controllable region.
