是仿真运行还是加载程序到实物运行?液晶屏是哪一类？根据液晶屏的参数、命令和时序调整程序就可以了

看你的代码，估计设置图形模式没有生效的结果。我这里的代码是经过实机测试过的。注意函数setGraphMode

         TransferData(*adder,1);
         adder++;
       }
    }
}

// 图片数据，16*64个字节的数据，对应于128*64个像素点
unsigned char code pic2[]= {
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x0F,0x78,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
......
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x08,0x01,0x2E,
};
实际显示图片时，执行以下代码
setGraphMode();            //调用LCD显示图片(扩展)初始化程序
DisplayGraphic(pic2);  //显示图片2
