Systems and methods of signal synchronization for driving light emitting diodes

A system for signal synchronization, the system comprising:

• a first signal generator configured to, in response to a first selection signal associated with a first operation mode satisfying one or more first conditions, generate a first clock signal based on at least information associated with a first input signal, the first input signal including an input rising edge and being associated with an input frequency, the first clock signal including a first clock rising edge and being associated with a first clock frequency;
• a second signal generator configured to, in response to the first selection signal satisfying one or more second conditions, generate a second clock signal, the second clock signal including a second clock rising edge and being associated with a second clock frequency;
• and
• a first gate drive component configured to,
• in response to the first selection signal satisfying the one or more first conditions, output a first drive signal to a first switch based on at least information associated with the first clock signal;
• and
• in response to the first selection signal satisfying the one or more second conditions, output a second drive signal to the first switch based on at least information associated with the second clock signal;
• wherein:
• the input frequency and the first clock frequency are the same;
• the input rising edge and the first clock rising edge both correspond to a first time;
• and
• the one or more second conditions are different from the one or more first conditions.
