The invention discloses a refreshing method of an electronic ink screen. A monitor is added to a drawing device of the electronic ink screen for monitoring the frame drawing updating frequency of all the electronic ink screen; when the updating frequency is higher than a threshold, the monitor emits a global notification to enable a refreshing manger to refresh the electronic ink screen by use of a refresh mode; and when the updating frequency is lower than a threshold, the monitor emits the global notification to enable the refreshing manager to refresh the electronic ink screen by use of a second refresh mode. Whether two preset refresh modes need to be converted is flexibly determined according to the frame drawing updating frequency of the electronic ink screen in the application process of a user. When a static image is watched for long time, a system determines that replacement of a refreshing mode is unnecessary and an original refreshing mode is always maintained. In case of animations or other images with quite high local refreshing frequencies, the system automatically converts the original refreshing mode into the first refreshing mode, high-frequency refreshing is automatically started, and the influence exerted by a ghost image on reading of the user is reduced.
