    • 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.
    • 同时在同一彩色显示单元上显示RGB格式彩色图像和YUV格式彩色图像的彩色显示驱动装置。 第一存储器存储YUV数据,并且YUV-RGB转换器将从第一存储器读取的YUV数据转换为RGB数据。 第二个存储器存储RGB数据。 屏幕显示(OSD)控制器将YUV数据和RGB数据分别写入第一和第二存储器,将由YUV-RGB转换器存储在第一存储器中的YUV数据转换的RGB数据与RGB 从第二个存储器读取的数据,并在屏幕上显示混合数据。
