A method for providing a gray scale in a field emission display (50) includes the step of providing a first driving pulse (214) having a pulse width equal to a pulse width separation (115) between the graphs (100, 200) of total charge response versus pulse width of a driving pulse for the non-ideal field emission display and the corresponding ideal field emission display. The pulse width separation (115) is the horizontal distance between the two graphs (100, 200) at a region wherein the two graphs (100, 200) are generally parallel. The pulse width, tn, of an nth driving pulse corresponding to an nth gray scale level is given by tn=t1+[n-1]*[(tN-t1)/(N-1)], wherein t1 is the pulse width of the first driving pulse (214), N is the total number of gray scale levels, and tN is the pulse width of the Nth driving pulse.
