Claim Text:
1. A method of driving a display device, where the display device comprises a first electrode having a respective first surface disposed in a first area, a second electrode having a respective second surface disposed in a second area, the second electrode being spaced apart from the first electrode, a lyophobic layer provided over the respective first and second surfaces of the first and second electrodes, a first partition wall on the lyophobic layer and a second partition wall on the lyophobic layer, a third electrode spaced apart from above, and facing the lyophobic layer, the method comprising: providing a first body of a first liquid as a first layer having a first thickness on the lyophobic layer, wherein the first layer extends from the first partition wall to the second partition wall; providing a second body of a second liquid as a second layer between the first layer and the third electrode, wherein the second layer extends from the first partition wall to the second partition wall, the second body of the second liquid being immiscible with the first body of the first liquid and the lyophobic layer being lyophobic with respect to the second liquid; and providing a first potential difference between the first electrode and the third electrode, causing the first liquid to coalesce over the second electrode in the second area, wherein the first liquid coalesces to have a second thickness that is greater than the first thickness; while reducing the first potential difference, providing a potential difference waveform between the second electrode and the third electrode, wherein the potential difference waveform includes two or more pulses, causing at least part of the first liquid to start spreading movement towards the first area; and at least partly after reducing the first potential difference, ceasing to provide the potential difference waveform, causing the at least part of the first liquid to slow down in the spreading movement toward the first area or to stop the spreading movement toward the first area.
