Abstract :
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 time has been proposed. Although the response time of the EPD is still lower than liquid crystal displays, the tool can automatically optimize the video quality under the specified data frame rate.
