Light emitting diode driving circuit, light emitting diode driving device and drive method

Provided are a light emitting diode driving circuit, a light emitting diode driving device and a drive method. The light emitting diode driving circuit is matched with a light emitting diode module, and comprises a reading address generating unit, a memory unit and a drive unit. The reading address generating unit receives a pulse signal and outputs a reading signal. The memory unit is in coupling with the reading address generating unit and generates an output signal according to the reading signal. The drive unit is in coupling with the memory unit, receives the output signal and the pulse signal, and outputs a drive signal to the light emitting diode module. According to the light emitting diode driving circuit, the light emitting diode driving device and the drive method, unnecessary power losses can be reduced, and processing efficiency is improved.
