Patent ID: 8345024

Claim:
A display system comprising: a display device including a display section having a dispersed system containing electrophoretic particles between a first electrode and a second electrode, wherein an electric field is generated between the first electrode and the second electrode according to display data, and the electrophoretic particles are migrated by the electric field so that an image corresponding to the display data is displayed; and a display-data providing device that provides a display control signal containing the display data to the display device, wherein the display system erases display content of the display section by generating an electric field between the first electrode and the second electrode according to display data corresponding to the display content; the display-data providing device stores display data to be provided to the display device and information corresponding to the display data in association with each other; and the display device holds the corresponding information associated with the display data provided from the display-data providing device, wherein: if the display data is not lost from the display device, the display device erases the display content according to a first inverted erase signal by use of the display data in the display device, and the first inverted erase signal is sent from the display-data providing device, and if the display data is lost from the display device, and if the display-data providing device identifies the display content indicated by the corresponding information contained in the display-data identifying signal output by the display device, the display device erases the display content according to a second inverted erase signal sent from the display-data providing device, and the second inverted erase signal includes the display data corresponding to the display content identified by the display-data providing device.
