Why use an e paper screen to make an e book instead of a black and white screen?

E-paper books are a kind of paper-like readers. Based on the latest display technology of e-ink, reading e-books is like reading paper books, which is comfortable and environmentally friendly, and does not hurt the eyes. At the same time, it also has the characteristics of large capacity and portability.

E-paper book is also the abbreviation of e-reader. It is generally believed that e-paper books refer to e-reading products that use eInk display technology to provide a similar reading experience to paper.

It is a new digital reader that uses e-paper as the display screen, and can read most of the e-books on the Internet in most formats such as pdf, chm, txt, etc. Compared with traditional mobile phones, MIDs, UMPCs and other devices, e-paper book readers using e-paper technology have the advantages of low radiation, low power consumption, and no harm to the eyes, and its display effect is realistic, which looks the same as the effect of reading a book.

Energy saving and environmental protection: once charged, the power-on state can be continuously standby for more than 15 days, no need to charge every day.

E-book ultra-low power consumption: unique intelligent power management technology, which can turn pages more than 7,000 times in a row.

Can store 1,000 books: 1GB memory card can store 500 million words, which is equivalent to nearly 1,000 sets of Romance of the Three Kingdoms.

There is only one thing that makes "e-paper book" manufacturers headaches: content. "It's like a TV producer, who doesn't have the energy to build a few new TV stations. ”

The overall ** of the "e-paper" reader is on the high side. ** Not only includes the cost of hardware, but also the investment in reading resources in the later stage is also a problem that businesses must considerFeng Xiaogang's new work "Do Not Disturb" to test the waters of "all** publishing", that is, traditional books, the Internet, mobile phones, "e-paper books" 4 forms. However, traditional publishing houses are too cautious and only give the copyright to the first half of the "e-paper book", and the second half has to wait for the paper book to be sold for a period before authorizing it.

In the face of the development of new technologies, traditional publishing houses are helpless, and bookstores are even more so.

The more formats supported, the better,The focus is on pdf, chm, doc and a variety of images、as well as zip、RAR and other compression formats,In this regard, domestic e-paper books are obviously superior,Among them, Hanlin V3 seems to be the most supported format (here is a list of some domestic e-paper books)。 On the contrary, foreign products support fewer formats, such as Amazon Kindle, which almost only supports proprietary formats.

Turning the page and black screen: In the process of using my colleague 505, I found that every time I turn the page, it is the whole screen that goes black first, and then it is displayed again in the way of "black on white", here is a v3, kindle, sony 505 page turning comparison**You can see the specific effect. This kind of page turning black screen effect is unbearable for me, here it is mentioned that Hanlin N516 is currently the only product in the world that does not turn pages black, but I believe that this solution will soon be popularized to various products.

The biggest difference between color screen e-books and black-and-white e-books is that the colors are different, and they are almost the same in terms of experience, after all, they are all e-books. In fact, e-books were launched as early as ten years ago, attracting many consumers who love reading with their advantages such as "low radiation and large screen"; And to the emergence of color screen e-books, so that the original imperfect e-books have successfully gained a foothold, so what is the division between black and white e-books and color screen e-books? The biggest difference is that the experience of color is different.

1. The earliest black-and-white e-books mainly imitate the mode of books, but there will always be overlapping shadows because of insufficient brightness

In the era of e-books, mobile phones have not yet been widely used, and many people will buy an e-book to experience the "reading feeling"; The technical limitations of that era led to the fact that e-books could only be displayed in black and white mode, which was indeed very book-read, but after long-term use, it would be found that the overlapping situation was more serious, which made many people have a kind of resistance to e-books. Even after mobile phones were widely promoted, the market for black and white e-books entered a downhill stage, and everyone would rather buy mobile phones than e-books.

Second, the color screen e-book is actually an evolved version of the black and white e-book, which has better improvements in color and superimposed shadows, but it is also hurtful to the eyes

The biggest difference between color screen e-books and black-and-white e-books is the difference in color and feeling; Compared with the traditional black dot e-book, color e-book can give readers a higher visual sense, and e-book has also developed from simple text to comics, and readers can see some free comics through e-books. Whether it is a black-and-white e-book or a color e-book, the damage to human eyes still exists, coupled with the improvement of the mobile phone system, many consumers prefer to buy tablets rather than e-books.

Color screen e-books and black-and-white e-books, the experience feels almost the same, and it can only be said that the evolved version of the color screen e-book looks more comfortable.

Colored e-paper has made the black, white and grayscale world colorful all at once, and some users are even looking forward to reading comics with color readers.

Black and white e-books will have more book texture, more simple, more attractive color screens, more able to concentrate when turned up, pleasing to the eye, especially when encountering e-books with pictures, the color screen experience is great.

The biggest difference is that it will be different when reading comics. The color ink screen will be more realistic, and the colors will be more vivid, while the black and white ink screen will be relatively inferior.

Color screen e-books are divided into liquid crystal and electronic ink, and now the mainstream domestic sales are light-emitting LCD screens, which are extended products of MP4**, the screen will glow, and there is no imitation of paper effect. In the world, there is a color screen e-book with e-ink, which is an upgraded product of black-and-white e-ink, so it has the same texture as black-and-white e-book, completely imitating paper, but this product is not popular, because it is high, about 2-3 times that of black-and-white e-book.

The above is just a conceptual distinction, and the following is the real one. I guess what you want to say is the mainstream luminous LCD color screen e-book in the domestic market, its screen is the MP4 screen, but because of the selling point of the "e-book", the brightness is deliberately reduced when it is manufactured, so that the user's eyes are not so stinging when staring at it for a long time. You're getting your question reversed.

It should be that the black and white e-book will flash when the page is turned and the color screen e-book will not flash when the page is turned away.

I also thought about choosing these products before, and finally I chose an iPod touch, which perfectly solved various needs.
