1, brand
Speaking of electronic paper books, I believe everyone will think of kindle for the first time. It is true that kindle is the first brand in the electronic paper book market, but besides kindle, there are actually many electronic paper book brands at home and abroad, such as Sony and kobo abroad, Hanwang as an old brand at home, and new brands such as Palm Reading, Dangdang, Jingjing and JD.COM.
Different brands of electronic paper books are very different, and their main functions are different. Some of them focus on their own book resources (such as kindle, palm reading), some focus on serving PDF reading (such as Sony, quiet reading), and some promote the opening of Android system (such as quiet reading), each with its own characteristics. What suits your needs best is the best.
Step 2 solve
After all, it is based on "seeing" equipment, and resolution is a very important indicator. At present, the common resolutions of electronic paper books are 167ppi, 2 12ppi and 300ppi. Most models with 6-inch screens have a resolution of 300ppi, models with 9.7 inches or more have a resolution of 167ppi, and the kindle entry version also adopts 167ppi. Theoretically, the higher the screen resolution, the better. A higher screen resolution will make the font display clearer. However, from the actual experience, 167ppi can actually meet the visual requirements under the normal reading distance, and it is not very vague. Perhaps this is one of the reasons why the kindle didn't give up the entry version.
3. Screen size
The importance of screen size for reading experience is self-evident. A larger screen means that more content can be accommodated and more layout requirements can be met. At present, there are three popular sizes: 6-inch, 9.7-inch and 13.3-inch. The 6-inch small screen is mainly used for reading pure text content, and reading books or cartoons in PDF format requires at least 9.7 inches. Of course, the bigger the screen, the worse the portability. 13.3 inch screen, which is quite inconvenient to carry. Comparatively speaking, 9.7 inches is a compromise choice, which can better meet the needs of reading comfort, layout adaptability and portability.
4. Touch and backlight
At present, most electronic paper books support finger capacitive touch, which is also in line with everyone's consistent operating habits on mobile phones. In addition to capacitive touch, some brands have specially added the handwriting function of electromagnetic pens, such as Sony, Hanwang and Jingjing electronic paper books. Add the stylus function, you can easily mark when reading, and you can write and draw. In particular, in-depth reading requires a handwritten annotation function. But also can be used as a daily notebook, which further advocates paperless life and is more environmentally friendly.
As for the backlight function, it is for reading at night. As we all know, the display of E-ink electronic ink screen depends on the ambient light source and does not emit light itself. Adding backlight can read normally in dark environment, but to some extent, it increases the stimulation to the eyes and becomes less eye-friendly. Moreover, if the backlight technology is not handled properly, it will lead to light leakage, yin and yang screens and other problems, which is also quite annoying.
5. System
In the development of electronic paper book 10 years, leap-forward technological innovation is actually rare. Kindle, the industry leader, has already entered the "micro-iteration period", and toothpaste-squeezing innovation can only make a fuss about narrow borders and fuselage modeling. Fortunately, the technical breakthrough of hardware is difficult, but the innovation of electronic paper book system is worth looking forward to.
Electronic paper book system can be divided into closed and open. Most manufacturers such as Kindle adopt a closed system, which euphemistically ensures an excellent reading experience. In fact, it binds users and promotes book consumption on its own platform. Kindle is like this, palm reading iReader is like this.
The other is to adopt an open Android system, such as a static electronic paper book, and deeply optimize the Android 4.4 system according to the characteristics of E-ink screen, so as to maximize the paper-like display effect of E-ink screen and the powerful expansion performance of Android, and bring a brand-new electronic paper book reading experience.
Traditional e-book manufacturers always take the number of books on the platform as their selling point, such as Kindle 300,000 and iReader 500,000. What about static e-books? You can install kindle APP, iReader, read more, read on wechat, etc. The richness of resources is far from a single platform. For personal books, you can also install a series of reading software to achieve better reading results. It is also a good choice to install news consulting apps such as today's headlines. Electronic paper book+Android system, rich reading function can liberate us from mobile phone reading to a certain extent, reading books and articles does not hurt our eyes, and focusing on reading is not interfered by mobile phones and does not waste mobile phone power. Very interesting!
