Abstract: An interleaving driving method of light emitting diode array comprises: receiving image signal; converting the image signal into gray scale signals, the gray scale signals correspond to the plurality of light emitting channels, respectively, to execute multiple steps. The multiple steps include: generating a high gray scale data group and a low gray scale data group; when there is data in the high gray scale data group, drive the light emitting diode channel corresponding to the target gray scale signal during a first turn on time interval; when there is data in the low gray scale data group, drive the light emitting diode channel corresponding to the target gray scale signal during a second turn on time interval which does not overlap the first turn on time interval and a first gray scale signal and a second gray scale signal of the gray scale signals does not overlap each other.
