摘要： A method of driving an electro wetting display panel includes applying a first data voltage to a pixel part of the display panel during a first section of a frame and applying a second data voltage different from the first data voltage to the same pixel part during a second section of the frame. The first data voltage is converted from display data based on a first gamma curve. The second data voltage is converted from the display data based on a second gamma curve. Light transmittance through the pixel part is changed based on movement of a fluid within the pixel part.
