LiquidCrystal::display
void LiquidCrystal::display()
This is the counterpart to noDisplay(). It turns the display back on. The display is on by default, so there is no need to call this at start, only after a call to noDisplay().
Usage:
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
lcd.begin(16, 2);
//some stuff that makes us want to turn the display off
lcd.noDisplay();
//do some stuff, wand LCD on again
lcd.display();
