The utility model provides an electronic paper module, a display device and a reading device. The electronic paper module comprises a temperature sensor, a heater, a controller, an upper substrate, a common electrode layer, a bonding layer, a microcapsule layer and a lower substrate, the temperature sensor is used for detecting the temperature of the electronic paper module and transmitting the temperature to the controller; the controller is used for receiving the temperature and comparing the temperature with a preset temperature threshold value, and if it is judged that the temperature is smaller than the preset temperature threshold value, the heater is controlled to be started so as to heat the electronic paper module. According to the embodiment of the invention, through the heater and the temperature sensor, the temperature of the electronic paper module can be adjusted in real time, the ghosting phenomenon at low temperature is effectively solved, and meanwhile, the picture can be quickly refreshed, s
