Abstract
Provided are a method and apparatus for controlling an ECD for reducing power consumption of the ECD. In The the method for of controlling an ECD coloredcoloring and decolored discoloring of an ECD by using a coloring voltage and a discoloring voltage, does not apply the coloring voltage and the discoloring voltage are not applied to the ECD after a lapse of predetermined time is passed from the time when the coloring voltage and the discoloring voltages are applied to the ECD. The apparatus for controlling an ECD blocks the coloring voltage and the discoloring voltage applied to the ECD after a lapse of predetermined time is passed from the start of coloring and discoloring operations to reduce power consumption of the ECD.
