Abstract
A driving system and a driving method for a planar organic electroluminescent device are provided. The light emitting device has multiple light emitting elements, each having a first electrode and a second electrode. The driving system includes a first circuit, a second circuit, a driving module, and a ground circuit. The first circuit is connected to and provides a constant voltage to the first electrode of each light emitting element. The second circuit is connected to the second electrode of each light emitting element. The driving module is respectively connected to the second electrode of each light emitting element through the second circuit. The ground circuit is connected to the driving module and connects each light emitting element to the ground. The first electrodes of the light emitting elements are connected to one another, and the light emitting elements are driven by a constant current output by the driving module.
