Abstract
A system and method of driving an electrowetting display device including a plurality of sub-pixels are presented. A target reflectance value for a sub-pixel in the plurality of sub-pixels is determined. A reflectance value of the sub-pixel is set to the target reflectance value by setting the reflectance value of the sub-pixel to a first reflectance value greater than a threshold value, and setting the reflectance value of the sub-pixel to the target reflectance value.
