A data displaying device for bidirectionally communicating with a far end service station by wired or wireless way is disclosed. According to the data sets displayed on the screen. the data displaying device selectively emits a request updating signal to a service station to request the service station to transfer part of updating data. Thus, the service station may reduce the transfer data amount greatly, thus the load of bandwidth is decreased. When a request updating signal is emitted to a service station, the data range of requesting a service station to send ordered updating data includes a data range of screen display.
