Electronic ink technology is the fundamental difference between Kindle hardware and other terminals-it enables the electronic screen to provide a texture and reading experience similar to traditional books, making the eyes less tired. At the same time, with the support of electronic ink screen, even under strong light, the screen of Kindle Paperwhite will not be reflective and unclear. The principle of this technology is also very interesting-in this screen, there are millions of small balls, and each ball has many white particles and black particles. The white particles are positively charged and the black particles are negatively charged. Then, under different voltages, the arrangement order of these particles is different, so that different chromaticity can be displayed on the screen and images can be presented on the screen.
In addition, I read a book saying that this technology has another advantage: "Once the page is formed, these particles stay in place, and no more power is needed, saving battery life."
In fact, this technology was not invented by Amazon, but developed by Xerox's Palo Alto Research Center. Sony also used it, but Amazon's 126 laboratory revolutionized this technology perfectly.
However, it is not perfect. In fact, this technology has also caused my biggest dissatisfaction with Kindle Paperwhite-because every time the particles are rearranged by changing the voltage, the speed is much slower than the electronic display screen we usually use, so when switching pages on Kindle paper, there will be a splash screen-like effect, which makes people very uncomfortable.
If electronic ink technology enables Kindle to read under strong light, then the backlight is designed to optimize the reading experience in dark conditions.
In most terminals we use today, the backlight is located at the bottom of the screen and emits light from the inside out. This design will be illuminated in two situations: 1. Long-term strong light exposure is easy to make people tired; In the dark, this strong light may disturb people around.
So when Amazon designed the Kindle, it adopted the opposite design idea-they put the light guide layer in front of the screen and lit the screen inward, thus solving the above two problems.
These are two core technologies that I think distinguish Kindle Paper from other terminals, and the experience they bring. In addition, the Kindle can stand by for 8 weeks in the darkest light screen, and the screen resolution is 62% higher than the normal level ... All these help it not only be as convenient to read as a paper book, but also be carried and read for a long time like a paper book. Of course, it also has functions that paper books don't have-changing font size, marking notes, storing and synchronizing in the cloud, sharing content and comments, and looking up dictionaries.
