Abstract— Interest in the use of electrophoretic displays for smart handheld applications has grown tremendously over the past few years. Since the launch of the Philips and E Ink joint development effort in February 2001, material parameters, TFT backplane, electronic hardware and software and modulization skills have been developed to make this promising display concept into a real product. The first commercial launch of active‐matrix electronic‐ink display modules is planned for mid 2004.

In this paper, we describe the first research prototypes of 5.0" diagonal QVGA active-matrix driven microencapsulated electrophoretic displays that utilize color filter arrays to produce color images.We report on the performance of the electrophoretic ink material and the color filter used in the display, and discuss the method by which the display was integrated to within required tolerances. The color display exhibits "paper-like" optics, in that the brightness and saturation of the optical states are largely independent of viewing or illumination conditions.

Interest in the use of electrophoretic displays for smart handheld applications has grown tremendously over the past few years. Since the launch of the Philips and E Ink joint development effort in February 2001, material parameters, TFT backplane, electronic hard‐ and software and modulisation skills have been developed to make this promising display concept into a real product and to build working commercial prototypes.
