A light-emitting device, especially for lighting and/or signaling for a motor vehicle, includes at least a first electroluminescent module and a second electroluminescent module energized in series. Each electroluminescent module includes, in parallel: a first branch having a light source having a first direct threshold voltage beyond which the light source is gated on, and a second branch having an element such that the voltage on the terminals of the element is less than the first direct threshold voltage of the light source. A third branch has a timing module able to time a predetermined period and modify, at the end of the predetermined period, an overall impedance of the second branch so that a voltage in the second branch is greater than the first direct threshold voltage of the light source. The predetermined period in the first electroluminescent module is less than that of the second electroluminescent module.

A method for controlling an amount of power delivered to an electrical load may include controlling an average magnitude of a load current towards a target load current that ranges from a maximum-rated current to a minimum-rated current in a normal mode, and controlling the average magnitude of the load current below the minimum-rated current in a burst mode. The burst mode may include at least one burst-mode period that comprises a first time period associated with an active state and a second time period associated with an inactive state. During the burst mode, the method may include regulating a peak magnitude of the load current towards the minimum-rated current during the active state, and stopping the generation of at least one drive signal during the inactive state to control the average magnitude of the load current to be less than the minimum-rated current.

The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.
