<P>PROBLEM TO BE SOLVED: To provide an electrophoretic display device or the like that prevents electrophoretic particles at high temperature from adhering and executes a display with high contrast. <P>SOLUTION: An electrophoretic display device includes: displaying means 3; temperature detecting means 41 and 42 for detecting use environmental temperature; and controlling means 60 for controlling a display of the displaying means 3. The controlling means 60 switches among display modes of the displaying means 3, more specifically among a first mode for executing a normal display, a second mode for executing a high temperature alarm display and a third mode for alternately executing mono-color displays of a first color and a second color. In the case where the use environmental temperature detected by the temperature detecting means 41 and 42 during the first mode is not less than a threshold temperature, the controlling means 60 switches from the first mode to the second mode. After a predetermined time period has elapsed since the display mode was switched to the second mode, the controlling means 60 switches from the second mode to the third mode. After the mono-color displays of the first color and the second color have been repeatedly executed by a predetermined number of times during the third mode, the controlling means 60 switches from the third mode to the second mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
