The electrophoretic display (EPD) has been popularly applied on electronic readers (E-Readers), but its response time is still a bottleneck such that none of commercial E-Readers can play videos on the EPD smoothly. In this paper, the detailed issues regarding the response time of the EPD are well addressed. An image processing tool based on the measured response speed under different image retention...
In this paper, we propose a real-time hardware engine that performs the image halftoning as well as the photometric calibration for coping with nonlinear optical response of electrophoretic displays (EPDs). The engine quantizes an input image into fewer gray levels on the fly to accommodate the EPD characteristics. Since the number of available gray levels as well as the electro-optical response is...
