Abstract: PURPOSE: A movable image display unit is to inform a public of a selected region of information about life of the selected region in real time using a radio frequency signal, thereby enhancing the efficiency of the information transmission in the selected region. CONSTITUTION: A movable image display unit comprises: a display panel(1) for displaying an image data; and a broadcasting control unit(10) for transmitting the image data to the display panel. A pager module(2) of the broadcasting unit receives information transmitted through a radio frequency telecommunication network and transmits the received information to a communication module(3). The communication module extracts a necessary information from the received information and stored the necessary information at a memory module(5). A process module(4) reads out a moving picture stored at a hard disk(6) or a CD ROM(7) and outputs the moving picture together with the necessary information to the display panel.
