Abstract
Electronic paper includes a display panel, a temperature sensor, and a controlling section. The display panel contains particles which move when a voltage is applied. The temperature sensor detects a temperature. The controlling section controls a rewriting operation to rewrite an image of the display panel by applying a rewriting voltage to the color particles. If a result of detection by the temperature sensor falls within a predetermined temperature range, the controlling section performs the rewriting operation after performing a preparatory operation to apply a preparatory voltage to the color particles.
