Abstract

The display system of the present invention includes: a body unit (1) for transmitting image data that has been generated; and a display device (2) for displaying an image in accordance with the image data that has been transmitted from the body unit (1), and said display system is characterized in that the body unit (1) and the display device (2) perform communications via radio communication means, and the body unit (1) and the display device (2) are separately providable. Thus, the radio transmission is used as communication means, and there is no cable, connecting the display device (2) and the body unit (1), that transfers the data signal, so that the device user can operate the system freely while watching the display device (2). As a result, it is possible to improve the workability of the user of the present display system. Further, since there is no wire connection section, using a connection clip, that is provided in a conventional display device, it is possible to simplify a mechanism for securing the strength of the wire connection section.
