    • 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.
    • 提供背光模块和驱动电路。 驱动电路包括多个电流源和电流切换单元。 电流源提供多个驱动电流。 电流开关单元耦合在多个发光元件串和用于将驱动电流传输到发光元件串的电流源之间,并且通过定时切换由发光元件串接收的驱动电流。 因此,可以使发光元件串的亮度相等。
