A control circuit for controlling an LED device according to an input data signal and a clock signal is disclosed. The control circuit includes at least one first control module. The first control module includes a shift register unit, a latch register unit, an LED driving circuit, and a latch signal generator. The shift register unit includes at least one shift register and is triggered by the clock signal for buffering data transmitted in the input data signal. The latch register unit includes at least one latch register and is triggered by a latch signal for latching data buffered by the shift register. The LED driving circuit is utilized for driving the LED device according to data latched by the latch register. The latch signal generator is used to generate the latch signal according to the input data signal and the clock signal.
