Quick Tutorial | TM1637 With Arduino | 4 Digit Display

[NewAquariumHobby]

Dear Sir, I made temp meter with Arduino & DS18B20 display on LCD working best, as LCD cost high so i brought 7 seg TM1637 but here i face problem. for example if i write this instruction
for(int i=0; i<=500; i++)
{
display.showNumberDec(i);
delay(3000);
}
LCD work best as i think LCD has inside controller which hold last instruction and keep display last digit for 3 sec delay time, but with 7 seg start flickering due to this 3 sec delay or if i do any calculation in code because may be 7 seg can't hold last instruction. Is there any solution for it to keep display digit for this 3 sec delay on 7 seg.
