Abstract:
1. A method of driving a display device comprising: in a first portion of a first frame, applying a first polarity data voltage to pixels disposed in odd columns and a second polarity data voltage to pixels disposed in even columns; in a second portion of the first frame, alternately applying the first polarity data voltage and the second polarity data voltage to pixels in the same row of pixels; in a first portion of a second frame, applying the second polarity data voltage to the pixels disposed in the odd columns and the first polarity data voltage to the pixels disposed in the even columns; and in a second portion of the second frame, alternately applying the first polarity data voltage and the second polarity data voltage to pixels in the same row of pixels, wherein the polarities of the data voltages applied in the second portion of the first frame are inverted from the polarities of the data voltages applied in the second portion of the second frame, wherein both the first polarity data voltage and the second polarity data voltage are applied to pixels in the same column in the second portion of the first frame, wherein the same polarity data voltage is applied to all pixels in the same column in the first portion of the first frame, and wherein the second frame immediately follows the first frame.
