Patent attributes
A reflective display device includes a display part including a fluid having dispersed therein particles having charges, an electric field applying unit including an electrode for applying an electric field to the display part, and a controller for controlling a color of light emitted from the display part, by adjusting at least one of an intensity, polarity, application time, number of applications, and application cycle of a voltage applied to the electric field applying unit, wherein the controller resets an alignment state of the particles by applying a driving voltage for controlling the color of light emitted from the display part, and then applying an alternating-current (AC) voltage having a polarity opposite to that of the driving voltage.
