摘要: The electrophoretic display (EPD) has become the main solution to electronic papers, but there are several limitations when it is being driven. First of all, optical response curve EPD nonlinear and temperature sensitive. In addition, number gray levels that can be displayed also quite limited. image quality unsatisfactory if images shown on panel not preprocessed increase visual compensate characteristics EPD. this paper, we present an integrated tool automatically estimate reflectance function curves under different ambient temperatures, perform adaptive halftoning improve quality, calibrate proposed approach been verified practical panels promising results have achieved.
