Abstract
A method of driving an electro-wetting display panel including a pixel part is provided. In the method, data voltages are applied to the electro-wetting display panel during a first time of a frame. The frame has the first time and a second time. The first time has a plurality of horizontal periods. The data voltages are generated based on reference gamma voltages. At least one of reference gamma voltages of one of the horizontal periods is different from another of the reference gamma voltages of another of the horizontal periods. A reset voltage is applied to the electro-wetting display panel during the second time of the frame.
