The present invention relates to an outdoor prefabricated LED signboard system, which is installed on an external wall of a building or an inside a building and displays a text, an image, etc., thereby outputting various types of information. The outdoor prefabricated LED signboard system comprises: a pixel panel on which LED elements are mounted; a pixel panel drive unit; LED modules which include finishing covers forming appearances; a connection fastening unit which couples one LED module and another LED module in contact with the one LED module, and connects input/output ports; a control module which provides output data; and a power module which supplies DC power required to drive the pixel panel drive unit and the control module. Accordingly, there are an effect in which LED signboards having various specifications can be assembled as desired by a user at a site at which the outdoor LED signboard system is to be installed, an effect in which a thickness of a light emitting part can be relatively reduced by separating the control module and the power module, an effect in which maintenance and repair of the outdoor LED signboard system is easy, and, in particular, an effect in which the outdoor LED signboard system can be installed by using an outside frame of an existing signboard installed on a wall of a building. |
