This week, Amazon has updated range of branded electronic books. In this case, the model name is not changed and remained the same as a year ago – Kindle Paperwhite, and from the published press release it was impossible to see what is new. In describing the new items had to say something about improving the contrast and the acceleration of paging through the use of a faster processor. Helped to clarify the essence of the changes later published In models of e-books last year, Amazon has used specially selected displays E Ink Pearl. Native contrast E Ink Pearl display is 10:1. For Kindle Paperwhite selected displays with 12:1 contrast ratio. The display contrast E Ink Carta increased to 15:1. Thus, compared to previous mass-screen generation contrast ratio increased by 50%. Black was black, and white whiter. Read with new products will be even more comfortable. What pleases the reflectance of new displays or White also became larger. According to the developers, this parameter has increased by more than 20%. In fact, the company itself flatter. The reflectivity of the E Ink Pearl equaled 40.7%. In Carta white screens increased to 44%. But even this increase will be noticeable on the white eye, if the old and new screens to compare what is called side-by-side. pixel density is on the screen E Ink Carta increased from “300 dpi” to “a little more than 300 dots per inch.” That said, at least on the resolution of 1024 x 768 pixels for a 6-inch display. But here it must be said that the size of the pixel E Ink depends mainly on the step of transistors on a TF-substrate. However, the film on the new step microcapsules “ink” may be even smaller, but there is no data. Finally, the developer says about a new technology refresh – Regal. Who used the devices with displays of E Ink, he knows that these screens tend to “wink” – a complete blackening of the image before upgrading the image. Thus, the residual artifacts are removed the previous image. As the technology of E Ink is an update needed less and less. The new displays, according to the company, in this respect, improved even more, which will further concentrate on reading without being distracted by irritating factors. In general, the refresh rate is not changed and is equal to 0.12 seconds. This technology is above your head will not jump. Animation on the E Ink screens as it was, and leaves much to be desired.
