A "lite" refers to individually framed glass pieces found within a window or door, while a "mullion" signifies the dividing line in a window or door, which can exist in either a physical or simulated form. In the context of True Divided Lites (TDL), the window glass comprises multiple distinct pieces, separated by mullions that traverse through the glass.
On the contrary, with Simulated Divided Lites (SDL), the glass remains a singular, large piece that has the mullions placed on top of it, that do not permeate the glass itself.
