Abstract
An electrophoretic display unit is presented that comprises an electrophoretic display panel (1). A medium (5) having embedded therein a plurality of electrophoretic display elements (7) is controlled by a first and a second pixel electrode (22b, 6). In addition a sensor constructed to generate a signal (ST) indicative for a temperature of the display panel and a driver (15) for driving the display panel (1) is provided. The sensor (250) includes a resistance sensor constructed to detect a resistance of the medium (5) between a first (22c) and a second sensor electrode (6), and the driver is controllable according to the resistance detected by the resistance sensor.
