Ubuntu Server : Turn off Laptop LCD/Monitor

Lately im installing Ubuntu Server 18.04 on laptop and wondering how to turn off the LCD because as a server it need to be turned on for 24 hours but the screen we dont need it as we can ssh from another machine.

To do this we will need vbetool utility. Get it by running sudo apt-get install vbetool from terminal.
