We fabricated a color electronic paper display (EPD) by using the charged particles. The display has 160 (×RGBW) × 480 array of pixels and four inch diagonal viewing area. Color filter technology was applied for coloration of the EPD. The fabrication process was as follows.
First, ITO electrodes were patterned on top and bottom substrates. Ribs were formed to define pixels on the bottom substrate, and color filters were deposited on the ITO of top substrate. The charged particles were put into the pixel arrays defined by the ribs. Finally, the top substrate having
the color filters was assembled on the bottom substrate. The resolution was 160 (×RGBW) × 480 with 4×4 inch area. The color gamut was about 2.49%, and the response time was 0.25 msec at 90 V. The contrast ratio was 2.36. The color EPD successfully demonstrated to display
Journal for Nanoscience and Nanotechnology (JNN) is an international and multidisciplinary peer-reviewed journal with a wide-ranging coverage, consolidating research activities in all areas of nanoscience and nanotechnology into a single and unique reference source. JNN is the first cross-disciplinary journal to publish original full research articles, rapid communications of important new scientific and technological findings, timely state-of-the-art reviews with author's photo and short biography, and current research news encompassing the fundamental and applied research in all disciplines of science, engineering and medicine.
