Claim Text:
1. A driving circuit, adapted to drive a plurality of light emitting element strings, the driving circuit comprising: a plurality of current sources, for respectively providing a plurality of driving currents; and a current switching unit, coupled between the light emitting element strings and the current sources, transmitting the driving currents provided by the current sources to each of the light emitting element strings in order for a plurality of periods equally divided in a time interval, wherein each of the driving currents is correspondingly and rotatably transmitted between the light emitting element strings over the plurality of periods, wherein the same light emitting element string receives different driving currents for two adjacent periods, and a light emitting brightness of each of the light emitting element strings are related to an average of the driving currents, wherein the current switching unit comprises:
