There is X% chance of a single point failure in a given size of screen.
If you are making 4 small screens, and a failure occurs, it will only occur in one of them, so you lose one screen, and keep three.
If you are making one large screen, and a failure occurs, you lose that screen.
Very simplistically, four times the screen area means four times more likely for a defect to occur on that screen.
