A method for determining and controlling performance of pre-charge operations of a plurality of source lines in an ESL system includes: obtaining voltage data of a plurality of lines of a frame to be displayed by a display module in the ESL system; determining whether pre-charge of the source lines in a rest period of a first line is required according to an amount of forthcoming voltage transitions to be generated on the source lines and accordingly obtaining a determination result; and controlling performance of pre-charge operations of the source lines in the rest period of the first line according to the determination result. When the amount of forthcoming voltage transitions to be generated on the source lines exceeds a predefined threshold, pre-charge of the source lines in the rest period of the first line is determined as required.
