LCD updating data from DHT11

Hi everybody, i’m doing my final school project and I can’t understand how to auto-updating the result on the LCD.
The code is the following:

#include <dht11.h>
dht11 DHT;
#define DHT11_PIN 4
#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C  lcd(0x3F, 2, 1, 0, 4, 5, 6, 7);
void setup()
{
  // activate LCD module
  lcd.begin (20, 4);
  lcd.setBacklightPin(3, POSITIVE);
  // lcd.setBacklight(LOW);
  //delay(1000);
  lcd.setBacklight(HIGH);
  lcd.home();
  lcd.print("UMIDITA'     TEMP");
}

void loop()
{
   lcd.setCursor(2, 2);
    int chk;
    chk = DHT.read(DHT11_PIN);    // READ DATA}
    // DISPLAY DATA
    lcd.print(DHT.humidity, 1);
    lcd.print("%      ");
    lcd.print(DHT.temperature, 1);
    lcd.print(" GRADI ");

  
}

Anyone could help me ? I’d like to use a delay but I don’t know where

I have done sorry.
