The radial direction may refer to a direction along a radius or a direction perpendicular to a rotation central axis of the LED light bar.
In this embodiment, a partition having the shortest distance to the rotation center of the LED light bar may be set as the first partition, a partition having the second shortest distance to the rotation center of the LED light bar (the second shortest distance to the rotation center of the LED light bar is the distance from the first partition to the rotation center of the LED light bar), and so on, and a partition having the farthest distance to the rotation center of the LED light bar may be set as the nth partition.
In the implementation of the application, the farther the partition is from the rotation center of the LED lamp strip, the smaller the standard refreshing angle is, namely the higher the refreshing frequency is (because the LED lamp strip rotates by one standard refreshing angle, the partition corresponding to the standard refreshing angle is refreshed once, the smaller the standard refreshing angle is, the higher the refreshing frequency is), the higher the refreshing frequency is, the display smear phenomenon of the lamp bead farther from the rotation center can be improved.

Step 404, detecting whether the number of the refresh cycles reaches the total number of the refresh cycles.
In the embodiment of the application, if the number of the refresh cycles is detected to reach the total number of the refresh cycles, it is determined that all lamp beads on the LED lamp strip finish one-time refreshing, that is, the refreshing of one scanning step length is finished; and if the number of the refresh cycles is detected to be less than the total number of the refresh cycles, determining that the partitions to be refreshed still exist in the N partitions, and returning to execute the step S403.
