Abstract
A backlight module and a driving circuit are provided. The driving circuit includes a plurality of current sources and a current switching unit. The current sources provide a plurality of driving currents. The current switching unit is coupled between a plurality of light emitting element strings and the current sources for transmitting the driving currents to the light emitting element strings, and switching the driving currents received by the light emitting element strings by timing. Therefore, the brightness of the light emitting element strings can be equalized.
