South Korea’s Kyobo Book Centre and the U.S. Qualcomm introduced the first commercial device with a color “electronic paper”.

Reader Kyobo eReader size 174 × 119 × 12,9 mm and weighing 340 g is equipped with a 5.7-inch color touch screen with Mirasol-1024 by 768 pixels and the density of packing 223 ppi. New works under the modified Android 2.3 and 1 GHz Qualcomm Snapdragon S2, there is a module Wi-Fi, 2GB of flash storage plus microSD-slot card, USB-port. Built-in LED light allows the reader to use in the dark. Touch control is implemented similar to the Barnes & Noble Nook Simple Touch – infrared grid. We claim that is able to work out Kyobo eReader for several weeks on one charge. The Reader retails for $ 310, but so far only in Korea.

Performed by Mirasol display technology, as well as the traditional “electronic paper” screen E Ink, suggest an extremely low power consumption, because power is spent only on updating pictures because of the bistability Mirasol-panels. There is no need and rear lighting, because it uses ambient light reflected from the mirror backing screen. Images visible even in bright sunlight. The main difference between Mirasol-from E Ink-panel concluded in the ability to display first color images and even videos.

Mirasol-display technology is based on interferometric modulation (iMoD), which is based on the idea of ​​forming a color image by interference of reflected light waves in a similar way as it occurs in nature, such as the wings of a butterfly. Each pixel iMoD-matrix consists of two elements: a translucent film (miniature Fabry-Perot interferometers) on a glass substrate and below it the reflecting mirror of the membrane. Depending on the membrane voltage changes its position, and between it and the film a gap, which depends on the size of the color. Office of interferometers by using microelectromechanical systems (MEMS) – tiny, micrometer sized mechanical elements, the so-called micromachines.
