Abstract
An electrophoretic display (EPD) with thermal control is disclosed for controlling and maintaining an image in extreme temperature environments. Techniques are also disclosed for maintaining the EPD cell threshold voltage for EPD cells comprising an EPD display media at or above a desired level in an environment in which the EPD may be subjected to an extreme temperature. The techniques comprise sensing a sensed temperature associated with the EPD display media, determining whether the sensed temperature satisfies a criterion established to ensure that the display media temperature remains at a level associated with an acceptable EPD cell threshold voltage, and in the event it is determined that the sensed temperature does not satisfy the criterion, controlling the EPD display media temperature as required to bring the sensed temperature to a level that satisfies the criterion.
