Abstract
A driving method of a multi-channel driving circuit includes: receiving multiple driving signals corresponding to multiple to-be-driven elements, providing multiple randomized time delays, respectively adjusting the driving signals according to the randomized time delays to generate multiple delayed driving signals, and respectively driving the corresponding to-be-driven elements according to the delayed driving signals.

A driving method of a multi-channel driving circuit, the driving method comprising:
- (a) receiving N driving signals corresponding to N to-be-driven elements, wherein the N driving signals are divided into M sets of driving signals, N and M are positive integers, N is larger than or equal to M, and M is larger than 2;
- (b) providing M different randomized time delays;
- (c) respectively adjusting the M sets of driving signals according to the M different randomized time delays to generate N delayed driving signals;
- and
- (d) respectively driving the corresponding N to-be-driven elements according to the N delayed driving signals.
