Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a display device and a display system. SOLUTION: The display device includes a RFID tag unit, a display unit, a processing unit and a power supply unit. The RFID tag unit follows a radio communication standard of a RFID system to receive a radio signal and outputs identification information. The processing unit electrically connected with the RFID tag unit and the display unit receives the identification information and outputs to the display unit for displaying. The power supply unit supplies operation power required to the processing unit and the display unit. The required power while the display device refreshes the information is supplied by the power supply unit, so that the information can be refreshed with comparatively longer communication distance and power saving is achieved. The display system including the display device and a reader/writer device is also disclosed. COPYRIGHT: (C)2010,JPO&INPIT
