Abstract
A half-tone display system for a flat matrix type CRT, in which, in displaying video signals such as television signals, half-tone display of n gradations is effected for one field, the one-field scanning signal frequency is made m times as high, and the data signal is made to perform the half-tone display of n/m gradations during a 1/m field period. With such a half-tone display system, the scanning frequency is made different from an AC drive source's frequency, and therefore the displayed picture is free from undesired beat interference or flickering phenomonon. Thus, the displayed picture is steady at all times.
