An OSD implementing device for a display system using multiple image processors and a method thereof are provided to generate OSD(On Screen Display) by one of a plurality of image processors and employ the OSD to image signals processed by another one, thereby realizing unified OSD and removing redundant hardware structures. An OSD implementing device for a display system using multiple image processors includes first and second processor parts(110,120) for carrying out predetermined image processing according to input image signal formats. An input part inputs image signals input from the outside to any one of the first and second processor parts. The first processor part has an OSD generating part(113) generates OSD data, a first image processor(111) for carrying out image processing for the input image signals, and a first mixer(117) for mixing the OSD data with the processed image signals. A first OSD control part(140) outputs the OSD data to the first mixer or the second processor part. The second processor part has a second image processor(121) for the image processing for the input image signals, and a second mixer(127) for mixing the OSD data input from the first OSD control part with the image signals processed by the second image processor.
