[Question - ILI9341]: TFT_off vs. TFT_wake

[hasenradball]

Hi,
whats the technical difference between TFT_off() and TFT_sleep()?

 void TFTweather::TFT_sleep() {
    // bring display into sleep
    tft.writecommand(0x10);
    // Delay for shutdown time before another command can be sent
    delay(5);
  }

  void TFTweather::TFT_off() {
    // switch off display
    tft.writecommand(0x28);
    // Delay for power supplies to stabilise
    delay(120);
  }

Is there any technical difference?

It will tell you in the datasheet. ISTR the tft.writecommand(0x10); shuts down the internal power to a minimum. tft.writecommand(0x28); simply blanks the display.

Thanks for the reply.
But the Back LED has to switched off separately right?
