TABLE OF CONTENTS Future displays [15] need to distinguish themselves in the area of power consumption, thickness, supporting electronics, size of the image, and viewing image.
Electronic Paper Displays, also called ePaper or electronic ink, is one of the most promising technologies for future display. The image looks like ink and paper and has very low power consumption due to bistability and "power-off" image retention. Electrophoretic displays (EPDs) are a technology enabled by electronic ink that carries a charge enabling it to be updated through electronics. Electronic ink is ideally suited for EPDs as it is a reflective technology which requires no front or backlight, is viewable under a wide range of lighting conditions, including direct sunlight, and requires no power to maintain an image. Some direct view ePaper contenders include iMOD and Electrophoretic.
Electronic ink is another promising technology for screens on mobile devices. It is many times brighter than an LCD screen and draws an order of magnitude less power. The concept of electronic ink follows the logic that displays should look very much like print on paper and behave like print on paper. That means the display should be flexible like paper.
Electronic ink is processed into a film for integration into displays. Electronic ink is a fusion of chemistry, physics, and electronics to create this new material. Electronic ink is made up of millions of tiny capsules, about the diameter of a human hair, containing...
