Not so long ago were created electronic ink, which are gradually beginning to replace the traditional ones.For many, this mysterious phrase unknown to all, some of his heard, but no one knows what it is.
At the end of the last century, scientists at MIT have developed a unique technology at the time of imaging.Also in 1997, he formed the corporation E-Ink.Its task was further improvement of the technology and its commercialization.She was making a profit on the display - devices, which are used in the creation of electronic ink.
principle of this device is extremely easy visual communication.Image formation in this device is as follows: the base of the active layer of the screen has transparent miniature capsules with pigment black and white.They react differently to the electric potential: white particles (positively charged) are attracted to the electrodes with a negative charge and black (negatively charged) for the positively charged terminals.
Electronic ink composed of microcapsules are so small that their diameter is equal to the human hair.In the neutral state, the black and white particles are in an arbitrary position inside the microcapsules.Attaching the back of the electronic-ink layer of the active area of the screen the positive charge, with all the white pigment particles move in front.At this time, the electron field affects the black particles, attracting the pigment to the "rear" side of the microcapsules.From the user's eye movements are hidden.The result of such actions will be the appearance on the electronic display white spots or white point.
electronic ink technology makes it possible by changing the polarity of the electric potential to get in the left side of the capsule black pigment particles, and the right - white.In this case, at this point, the screen will form a black spot.In order to obtain large complex images, you need to form a matrix, the control electrodes.For example, a system of this type is used in LCD displays.Electronic ink will allow to transfer the image on the segment or symbol matrix, which will be located on the active area of the screen.
E-Ink Corporation has partnered with manufacturers of color filters used in flat panel monitors.This allows you to develop a new type of color displays.
The developed technology of electronic ink allowed to start production of displays with high resolution.They are used in PCs, e-books, mobile communication devices, and so forth. It was designed to ensure the full communion with the user through a variety of electronic devices at the level of visual information.This information is read from the screen of the device like a normal paper.Because of the similarity of the technology is also called "electronic paper."It allows you to create a readable, portable image.
This color electronic ink is very stable, and the formed image can remain legible for a few months.When reading is no flicker, do not change the letters, so do not create additional difficulties for the perception of information.In addition, no impact angle of view and lighting conditions, and the technology is characterized by ultra-low power consumption, which is consumed mostly in the screen refresh.Another characteristic is that the image may be 100 times less than that of a mobile phone.Color electronic ink have reflectivity 6 times more and twice more contrast LCD screens.
