Claim:
1. A method for driving light-emitting elements, comprising: providing m current paths coupled in a parallel configuration, wherein each current path includes a light-emitting element and wherein m is an integer; sequentially turning on and off a plurality of light-emitting elements in the m current paths, including turning on and off a first light emitting element of the plurality of light emitting elements in a first current path of the m current paths then turning on and off a second light-emitting element of the plurality of light emitting elements in a second current path of the m current paths, wherein each light-emitting element is illuminated for a first light-emission time and wherein a sum of the first light-emission times of the m light-emitting elements is a first light emission period; and adjusting the first light-emission time to a second light emission time in response to a change in the first light-emission period.
