Abstract
A method is disclosed for controlling charging/discharging of a capacitor module. The capacitor module includes a plurality of branches connected in parallel, each of which includes a capacitor and a switch connected in series with the capacitor. The method includes measuring a first charge/discharge time for the capacitor module being charged/discharged from an initial voltage to an intermediate voltage, and To adjusting a second charge/discharge time for the capacitor module being further charged/discharged from the intermediate voltage to a target voltage by controlling on/off of at least one of the switches depending on the first charge/discharge time, the intermediate voltage being between the initial voltage and the target voltage. Also disclosed are an apparatus for controlling charging/discharging of a capacitor module and a display apparatus including the apparatus.
