SD card log data to OLED or LCD screen

I was wondering if anyone has a code snippet of displaying a csv log data on the SD card to the display? Right now I can use the example from the SD library:Serial.println(dataString); to view the data on the computer screen but I need some way of breaking up the dataString for the display, then moving down a line and displaying the next log. Right now I can log data, stop logging, verify the log exists by viewing it on a pc, then clearing the log file. I wont post my code since I just need a basic idea of what to do.
