Driving circuit of light emitting diode and ghost phenomenon elimination circuit thereof

A ghost phenomenon elimination circuit adaptable for a driving circuit of a light emitting diode, wherein a current driving unit of the driving circuit has at least one current driving terminal, and the current driving terminal has an output timing corresponding to a gray scale clock signal, comprising:

• a ghost phenomenon elimination unit coupled to the current driving terminal, for adjusting a voltage level of the current driving terminal according to an enable signal;
• and
• a counter unit coupled to the ghost phenomenon elimination unit, for counting the gray scale clock signal to determine a black insertion period and output the enable signal to the ghost phenomenon elimination unit during the black insertion period;
• wherein the ghost phenomenon elimination unit pulls up the voltage level of the current driving terminal to a high voltage level according to the enable signal.
