Patent ID: 8654047

Claim:
An electro-optic device, comprising: an electro-optic panel that includes a pixel region having a plurality of pixels that are arranged at a plurality of intersections where a plurality of scanning lines and a plurality of data lines cross each other; a polarity reverser that reverses, at a first frequency, a polarity, with respect to a common voltage, of video signals that are supplied to the plurality of pixels; a light source that emits light onto the pixel region; a pulse driver that pulse-drives the light source at a second frequency that is not a multiple of the first frequency; and a setter that sets the first frequency and the second frequency so that a difference value between each of a plurality of first frequency components of the first frequency and each of a plurality of second frequency components of the second frequency is greater than a predetermined threshold value, wherein the predetermined threshold value is not less than 14 Hz, and wherein the first frequency is not a multiple of the second frequency.
