你就不能将switch(key)
改成
switch(key / 10)
{
      case 3 :{WriteDataToREG(0x10,0x2b); //显示图形1
                              WriteDataToREG(0x00,0xc5);
                              lcd_photo(tab4);
                              Delay_Nms (3000);break;  }
      case 4 :{  WriteDataToREG(0x10,0x2b); //2b写汉字,3d写英文(粗字),
                              WriteDataToREG(0x00,0xc5); //0xcd写文字,0xc5写图形
                              lcd_photo(tab5);
                              Delay_Nms (3000);break; }
      case 5 :{WriteDataToREG(0x10,0x2b); //2b写汉字,3d写英文(粗字),
                              WriteDataToREG(0x00,0xc5); //0xcd写文字,0xc5写图形
                              lcd_photo(tab6);
                              Delay_Nms (3000);break; }

   case 6 :{WriteDataToREG(0x10,0x2b); //2b写汉字,3d写英文(粗字),
                              WriteDataToREG(0x00,0xc5); //0xcd写文字,0xc5写图形
                              lcd_photo(tab7);
                              Delay_Nms (3000);break; }

   case 7 :{WriteDataToREG(0x10,0x2b); //2b写汉字,3d写英文(粗字),

                              Delay_Nms (3000);break; } // 减键

   default :
            break;
}
