Abstract
The invention describes an Organic Light Emitting Device (1) comprising
- an active layer (13) between a first electrode (11) and a second electrode (12);electrical connectors (3, 34);a plurality of current distributors (21) for electrically contacting at least the first electrode (11),a plurality of selectively addressable current distribution lines (24, 25) being arranged to extend between the electrical connectors (3, 34) and the current distributors (21);a power supply (100) being electrically connected to the electrical connectors (3, 34), the powers supply (100) comprising a controller (110), the controller (110) being adapted to control a current flow to the current distributors (21) based on electrical parameters characterizing the brightness of an area (22) of the Organic Light Emitting Device (1) around the current distributors (21), andat least one sensor (200), the sensor (200) being adapted to measure data being relevant for the brightness distribution of the Organic Light Emitting Device (1), and the controller (110) being adapted to adapt the electrical parameters based on the data measured by the sensor (200). The invention further describes a corresponding method of controlling the brightness distribution of an Organic Light Emitting Device (1) and a method of driving the Organic Light Emitting Device (1). The sensor enables a feedback loop for locally controlling the brightness of the Organic Light Emitting Device (1) by means of the current distributors (21).
