Abstract
The invention relates to light-emitting diodes (O-LED). In particular, it relates to the driver electronics needed for these devices. An organic electroluminescent device is provided, which has a hermetically closed very flat housing. To improve the functionality of an O-LED, considerably reduce the height of an O-LED module and allow a cost-effective mass production, the driver circuit and the electronic driver elements or the printed circuit board (PCH) with the electronic driver elements are incorporated into the cover plate of the device.
