E Ink (electronic ink) is a popular type of electronic paper display technology, characterized by high visibility and contrast, a wide viewing angle and low power requirements. The technology has been commercialized by the E Ink Corporation, which was co-founded in 1997 by MIT undergraduates J.D. Albert & Barrett Comiskey, MIT Media Lab professor Joseph Jacobson, Jerome Rubin and Russ Wilcox.
It is currently available commercially in grayscale and color and is commonly used in mobile devices such as e-readers, and, to a lesser extent, digital signage, mobile phones, smartwatches, electronic shelf labels and architecture panels.
E Ink is processed into a film for integration into electronic displays and has enabled novel applications in phones, watches, magazines, wearables and e-readers, etc. Advantages of E Ink include low power usage, flexibility, durability and ruggedness and better readability under direct sunlight. Given these properties, E Ink displays can be used for a broad range of surfaces and solutions.
