It all depends on if the delta symbol is supported on you LCD model. What is your model LCD? You would need to go look through the data sheet to find out. If it is not, most LCD's support custom symbols in which the data sheet will tell you how to create them.

the following sketch shows how you can create and display a custom character

#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

byte delta[8] =
{
  B00000,
  B00000,
  B00100,
  B01010,
  B11111,
  B00000,
  B00000,
  B00000
};



void setup() {
  lcd.createChar(0, delta);
  lcd.begin(16, 2);
  lcd.write(0); // display the custom character

}

void loop() {

}

You can modify the bits in the delta array to change the appearance.
1 turns on the pixel, 0 turns it off.
