Abstract
An equalizing method for a driving device includes determining whether a polarity of an output voltage changes from a first time period to a second time period according to an inversion method of a display device coupled to the driving device, for generating a polarity inversion signal; and determining whether to perform an equalization operation on the output voltage in a switching period between the first time period and the second time period according to the polarity inversion signal, current line information and previous line information.
