A flicker frequency detection method includes defining a plurality of adjacent sensing sections of the same size on a display panel based on an M Hz frequency, an N Hz frequency and the panel resolution, calculating a reference average signal detected by a first sensing section, calculating a first average signal detected by an (n+1)th sensing section, calculating a second average signal detected by an (m+1)th sensing section, calculating a first difference value between the first and reference average signals, calculating a second difference value between the second and reference average signals, determining a relationship between the first and second difference values, and outputting corresponding signals based on the relationship between the first and second difference values. The ratio between the area covered by the first through mth sensing sections and that covered by the first through nth sensing sections is proportional to the ratio between M and N.
