ABSTRACT:
A color display driving apparatus that simultaneously on-screen displays an RGB format color image and a YUV format color image on the same color display unit. A first memory stores YUV data, and a YUV-RGB converter converts YUV data read from the first memory to RGB data. A second memory stores RGB data. An on-screen-display (OSD) controller writes the YUV data and the RGB data in the first and second memories, respectively, mixes the RGB data converted from the YUV data stored in the first memory by the YUV-RGB converter with the RGB data read from in the second memory, and on-screen displays the mixed data.
